Abstract
A polyester die plastic product of which the cross section is a shell-shaped or sheet-shaped body is characterized in that: the shell-shaped or sheet-shaped body is a layer structure; a middle layer is polyester die plastic, and the upper and lower layers are the fiber cloth with adhesive sucked; or the middle layer is the fiber cloth with adhesive sucked, and the upper and lower layers are polyester die plastic. The strength is improved over 30 percent, while the cost is increased less than 10 percent; under the condition of ensuring the strength, the production cost of product can be reduced 20 percent, and the product weight is reduced 20 percent.
Description
Technical field
The utility model relates to mechanical-moulded goods of fiberglass and forming technique.
Background technology
The intensity of polyester molding product depends on fibre length and the content in the film plastics, generally speaking increasing with the intensity of manufactured goods of the lengthening of fibre length and content is directly proportional, yet determined that the length of fiber can not be greater than 70mm owing to make the characteristic of the plant equipment of SMC sheet material or manufacturing BMC group material, simultaneously because the oil absorbency of SMC/BMC sheet material or group's material work in-process fiber is not 0, therefore the recruitment of fiber also is limited, and in real work, consider the cost problem, fiber roll up the increase that also can bring cost apace.
The moulding of traditional laminar film plastics (SMC/BMC) is the compression molding method that adopts the metal pair mould.Its technical process is very simple; as long as the SMC sheet material or the BMC group material that meet the requirements are cut into required shape; determine the adding quantity of raw material with product weight; throw off the diaphragm on SMC two sides; superimposed and be placed on the appropriate location of mould by requirement necessarily, the extrusion forming of can technological parameter in accordance with regulations heating.Its technological process as shown in Figure 5.
Summary of the invention
The purpose of this utility model provides a kind of polyester molding product and forming method thereof, and it has the intensity that is higher than existing polyester molding product, and cost only has a small amount of increase.
The technical solution of the utility model is: a kind of polyester molding product, the cross section of its body is hull shape or sheet body, it is characterized in that: hull shape or sheet body are layer structure, the intermediate layer is a polyester molding compound, two-layer up and down for inhaling the fiber cloth that glue is arranged, or the intermediate layer is for inhaling the fiber cloth that glue is arranged, and two-layer up and down is polyester molding compound.
Aforesaid polyester molding product is characterized in that: two-layer up and down suction has the fiber of glue to be furnished with multilayer, or the fiber in intermediate layer is furnished with multilayer.
The forming method of polyester molding product is, fiber cloth or the fiber cloth and the polyester molding compound that soaked glue are put into moulding to mould, before the extrusion forming of heating, fiber cloth or the fiber cloth and the polyester molding compound that soaked glue are placed by following overlapped way: the intermediate layer is a polyester molding compound, two-layerly up and down be the fiber cloth or the fiber cloth of soaking glue, or the intermediate layer is the fiber cloth or the fiber cloth of soaking glue, and two-layer up and down is polyester molding compound.
Beneficial technical effects
Polyester molding product of the present utility model, its intensity improves more than 30%, and increases cost less than 10%.Expect with structure of the present utility model and new technology manufacturing with same SMC sheet material or BMC group, product surface is surrounded by the longitude and latitude grid, simultaneously because in the compression molding process, under powerful pulling force effect, make the longitude and latitude grid produce stronger prestressing force, product strength is improved greatly, as the effect of reinforcing bar in cement.Because in mold process, a sheet material/material is liquefied in heating process, therefore solidifies back fiber cloth and sheet material/expect one integrated mass already at chemical reaction, thus goods when running into external force, the decentralization of power is splendid, thereby also shows the raising greatly of intensity.Intensity can improve more than 30% after tested.
2, guaranteeing to reduce goods manufacturing cost 20% under the condition of intensity, reducing product weight 20%.As everyone knows, the thickness of the goods of moulding compound and the relation of intensity are proportional relations, therefore reducing thickness is exactly the weight that reduces goods, reduce the use of raw material exactly, basically be exactly to have reduced cost, reduce cost 20% exactly because intensity has improved 30%, only make cost increase by 10% and put into the required input of gaining in strength.

Concrete embodiment
Embodiment 1 of the present utility model as depicted in figs. 1 and 2, the cross section of the body of its polyester molding product is that hull shape or sheet body are a layer structure, the intermediate layer is a polyester molding compound 2, the upper strata is for inhaling the fiber cloth 1 that glue is arranged, lower floor is for inhaling the fiber cloth 3 that glue is arranged.
The forming method of polyester molding product is, fiber cloth or the fiber cloth and the polyester molding compound that soaked glue are put into moulding to mould, before the extrusion forming of heating, fiber cloth or the fiber cloth and the polyester molding compound that soaked glue are placed by following overlapped way: the intermediate layer is a polyester molding compound, two-layerly up and down be the fiber cloth or the fiber cloth of soaking glue, or the intermediate layer is the fiber cloth or the fiber cloth of soaking glue, and two-layer up and down is polyester molding compound.
Concrete mode can be carried out according to the following steps:
Before the extrusion forming of heating, with the lower floor's fiber cloth or the fiber cloth of soaking glue, the full moulding of tiling earlier is to the counterdie of mould, by the conventional moulded moulding process SMC or the BMC material for preparing is placed on the appropriate location of mould again, then again top fiber cloth or the fiber that soaked glue are covered with and are layered on SMC or the BMC material, the extrusion forming of heating of technological parameter routinely.Briefly, be exactly fiber cloth with the SMC/BMC feed collet in the centre, again by traditional process moulding.
Also can before putting, with anchor clamps fiber cloth and polyester molding compound be pressed a layer structure clamping earlier, put into moulding then together, press traditional process moulding behind the removal anchor clamps again mould as mould.
Claims (2)
1. polyester molding product, the cross section of its body is hull shape or sheet body, it is characterized in that: hull shape or sheet body are a layer structure, the intermediate layer is a polyester molding compound, two-layer up and down for inhaling the fiber cloth that glue is arranged, or the intermediate layer is for inhaling the fiber cloth that glue is arranged, and two-layer up and down is polyester molding compound.
2. polyester molding product as claimed in claim 1 is characterized in that: two-layer up and down suction has the fiber of glue to be furnished with multilayer, or the fiber in intermediate layer is furnished with multilayer.
