Description
技术领域：Technical field:
本发明涉及塑料板材技术领域，特指一种由发泡塑料层与硬性塑料层复合而成的复合塑料板。The invention relates to the technical field of plastic plates, in particular to a composite plastic plate composed of a foamed plastic layer and a rigid plastic layer.
背景技术：Background technique:
目前在市面上销售的塑料板都为单层发泡板或单层硬性塑胶板，单层发泡板虽然重量轻，但是表面硬度低，表面物理刚性差，不能抵抗强的冲击力、摩擦力，表面易磨损，并且表面粗糙、光洁度差，即使通过涂覆油漆或其他表面加工技术可达到光亮的效果，但它的色相仍然较差；硬性塑胶板的硬度高，能抵抗强的冲击力、摩擦力，通过表面加工也可作到表面光滑，喷上油漆后色相也好，但它的密度高，往往重量沉，使用起来不方便。The plastic boards currently on the market are single-layer foam boards or single-layer rigid plastic boards. Although single-layer foam boards are light in weight, they have low surface hardness and poor surface physical rigidity, and cannot resist strong impact and friction. , the surface is easy to wear, and the surface is rough and the finish is poor. Even if the bright effect can be achieved by coating paint or other surface processing technology, its hue is still poor; the hardness of the rigid plastic plate is high, and it can resist strong impact. Friction, the surface can also be made smooth through surface processing, and the hue after spraying paint is also good, but its density is high, often heavy, and it is inconvenient to use.
发明内容：Invention content:
本发明的目的就在于克服上述缺点。The object of the present invention is to overcome the above-mentioned disadvantages.
本发明是通过如下技术方案实现的：三层共挤发泡板的制造方法，其特征在于：该三层共挤发泡板的中间发泡层及在发泡层两表面分别覆盖着的硬性塑料层，经过共挤一体成型。The present invention is realized through the following technical scheme: the manufacturing method of the three-layer co-extrusion foam board, which is characterized in that: the middle foam layer of the three-layer co-extrusion foam board and the rigid hard foam layer respectively covered on the two surfaces of the foam layer The plastic layer is integrally formed by co-extrusion.
三层共挤发泡板的发泡层由化学发泡方式制成，以化学发泡剂混合原料，制作出密度为0.5g/cm3～0.8g/cm3的发泡层。The foam layer of the three-layer co-extruded foam board is made by chemical foaming, and the chemical foaming agent is used to mix raw materials to produce a foam layer with a density of 0.5g/cm 3 to 0.8g/cm 3 .
三层共挤发泡板的发泡层由物理发泡方式制成，以二氧化碳或丙烷或丁烷气体作为发泡剂，直接打入挤出机，制作出密度为0.6g/cm3～0.6g/cm3的发泡层。The foam layer of the three-layer co-extruded foam board is made by physical foaming. Carbon dioxide or propane or butane gas is used as the foaming agent, which is directly injected into the extruder to produce a density of 0.6g/cm 3 ~0.6 g/cm 3 foam layer.
本发明所提供方法制成的三层共挤发泡板，其表面色相好，可根据需要做成不同颜色，同时在生产过程当中可以一次成型，大大降低生产成本。The three-layer co-extrusion foam board produced by the method provided by the invention has a good surface hue and can be made into different colors according to needs, and can be molded at one time during the production process, greatly reducing production costs.
该三层共挤发泡板用于制成公文夹、卷宗夹、德国夹、图档袋、旅行箱、相薄、箱盖、置物箱或用作医药用包装材料、避震用外包装材料、汽车用装饰材料、食品用包装材料、建筑用材料或运动器材。The three-layer co-extruded foam board is used to make briefcases, file folders, German folders, picture file bags, suitcases, photobooks, case covers, storage boxes, or as medical packaging materials, shock-absorbing outer packaging materials , automotive decoration materials, food packaging materials, construction materials or sports equipment.
附图说明：Description of drawings:
附图1为三层共挤发泡板的结构示意图Accompanying drawing 1 is the structural representation of three-layer co-extruded foam board
具体实施方式：Detailed ways:
如图1所示，三层共挤发泡板的中间发泡层(1)及在该发泡层两表面分别覆盖着的硬性塑料层(2、3)，其发泡层(1)的厚度比硬性塑料层(2、3)各自的厚度大，该三层共挤发泡板经过共挤一体成型。As shown in Figure 1, the middle foam layer (1) of the three-layer co-extruded foam board and the rigid plastic layers (2, 3) covered respectively on the two surfaces of the foam layer, the foam layer (1) The thickness is larger than that of the rigid plastic layers (2, 3), and the three-layer co-extruded foam board is integrally formed through co-extrusion.
该三层共挤发泡板的发泡层(1)及硬制塑料层(2、3)可以分别选择使用热可塑性塑胶材料制成，其热可塑性材料塑胶材料为聚丙烯、聚乙烯、聚苯乙烯、乙烯醋酸-乙细酯或聚氯乙烯。The foam layer (1) and hard plastic layers (2, 3) of the three-layer co-extruded foam board can be made of thermoplastic plastic materials respectively, and the thermoplastic material plastic materials are polypropylene, polyethylene, polyethylene, etc. Styrene, vinyl acetate or polyvinyl chloride.
该复合板发泡层也由化学发泡方式制成，以化学发泡剂混合原料，制作出密度为0.5g/cm3～0.8g/cm3的发泡层。The foaming layer of the composite board is also made by chemical foaming, and the chemical foaming agent is used to mix raw materials to produce a foaming layer with a density of 0.5g/cm 3 -0.8g/cm 3 .
如果欲降低密度小于0.5g/cm3的瓶颈，本人又研发出可采用物理发泡方式，以二氧化碳或丙烷或丁烷气体作为发泡剂，直接打入挤出机，制作出密度为0.6g/cm3～0.03g/cm3的发泡层，使该三层复合板重量减轻50％～95％，同时表面的刚性仍可大幅增大，且表面设相好，可根据需要做成不同颜色。If you want to reduce the bottleneck with a density of less than 0.5g/ cm3 , I have developed a physical foaming method, using carbon dioxide, propane or butane gas as a foaming agent, and directly injecting it into the extruder to produce a density of 0.6g. /cm 3 ~0.03g/cm 3 of the foam layer can reduce the weight of the three-layer composite board by 50%~95%, and at the same time, the rigidity of the surface can still be greatly increased, and the surface is well designed, and can be made into different colors according to needs .
其发泡层(1)亦可采用回收再生材料制成，不但符合环保要求，同时又减少了成本，是复合板成本大为降低。The foam layer (1) can also be made of recycled materials, which not only meets the requirements of environmental protection, but also reduces the cost, so that the cost of the composite board is greatly reduced.
采用上述方法制成的三层共挤发泡板可用于制成公文夹、卷宗夹、德国夹、图档袋、旅行箱、相薄、箱盖、置物箱或应用作为医药用包装材料、避震用外包装材料、汽车用装饰材料、食品用包装材料、建筑用材料或运动器材。The three-layer co-extruded foam board made by the above method can be used to make briefcases, file folders, German folders, picture file bags, suitcases, photobooks, box covers, storage boxes or used as medical packaging materials, avoidance boxes, etc. Outer packaging materials for earthquakes, decorative materials for automobiles, packaging materials for food, construction materials or sports equipment.
