Abstract
The invention provides a manufacturing method of a polyurethane wear-resisting pipe. The manufacturing method comprises the following steps of manufacturing and heating a die; proportioning big and small polyurethane materials; heating a polyurethane pipe; and vulcanizing the polyurethane pipe. According to the manufacturing method of the polyurethane wear-resisting pipe, provided by the invention, the wear-resisting degree of an obtained polyurethane wear-resisting pipe is 3-4 times higher than that of the traditional common rubber wear-resisting pipe, and the polyurethane wear-resisting pipe can be widely used in wear-resisting, anti-corrosion and anti-scale pipeline conveying systems in the fields such as electric power, metallurgical mine, petrochemical industry, coal and building materials. The manufacturing method provided by the invention has the advantages that the operation is simple, the cost is low, and the applicability is very strong.
Description
Technical field
The invention belongs to wear-resistant pipe technical field, particularly relate to a kind of preparation method of polyurethane wear-resistant pipe.
Background technology
Current China is for carrying the mainly rubber tube of sandstone, breeze, and this rubber tube is hardness steel wire or wire netting in the sulfuration of rubber tube inwall, strengthens pipeline scuff resistance, increases the service life.But because steel wire comparatively thin (too slightly affecting again the elasticity of rubber tube) is difficult to the long-term impact of the transported substances such as opposing sandstone, particularly after the abrasion of rubber tube wall, steel wire or wire netting just peel off rubber tube wall, cause transported substance to block, terminate the service life of rubber tube.
Summary of the invention
The scuff resistance that the present invention is directed to the rubber tube existence used in existing sandstone, breeze conveying is low, and service life is short, once steel wire or wire netting peel off rubber tube wall, will cause the problems such as transported substance blocking, propose a kind of preparation method of polyurethane wear resistant pipe.
The embodiment of the present invention is achieved in that a kind of preparation method of polyurethane wear-resistant pipe, and this preparation method comprises the following steps:
Make mould;
Heating mould;
The large small powder of proportioning polyurethane;
Heating polyurethane tube;
Sulfuration polyurethane tube.
Further, making the implementation method of mould is: choose internal diameter be 63 high carbon steel pipe and purlin mill, choose external diameter be 51 high carbon steel pipe and purlin mill, outer tube intercepts pipe in 2.05 meters and intercepts 2.30 meters.
Further, the implementation method of heating mould is: by mold heated 2---3 is little of temperature 130 degree.
Further, the implementation method of the large small powder of proportioning polyurethane is: aniseed is heated to 85---90 degree, small powder is heated to 110 degree, after the two mixes, and adds in the mould of setting with funnel, has 51 and 63 grooves in mold base.
Further, the implementation method of heating polyurethane tube is: leave standstill mould about ten minutes, the mould that fell enters heating cabinet, constant temperature 130 degree, 45 minutes to 1 hour, then takes out polyurethane pipe.
Further, the implementation method of sulfuration polyurethane tube is: clean pipe two ends use acetone treatment agent with carrene, prepare raw material, by hand two is caught to 20 meters of long pipes after raw material wire drawing after process, after enter vulcanizing tank, sulfuration more than ten hours.
Further, clean pipe arm once afterwards with raw material coating body and rubber cloth with carrene after sulfuration, body is wrapped with one deck rubber cloth, weaves after then wrapping one deck glue.
The preparation method of polyurethane wear resistant pipe provided by the invention, the polyurethane wear resistant pipe obtained is 3 of existing General Purpose Rubber wear-resistant pipe rub proofness---4 times, can be widely used in the pipeline transport system of wear-resisting, corrosion-resistant, the good antiscale property in the fields such as electric power, metallurgical mine, petrochemical industry, coal, building materials.This preparation method is simple to operate, and cost is low, has very strong application.
