Abstract
The invention discloses a polyvinyl chloride foamed internally and externally-crusted foaming pipe. According to the foaming pipe, materials are stirred uniformly, the foaming pipe is formed by extruding the materials by an extruder, and the foaming pipe cooled quickly by cooling liquid to ensure that crusts are formed on internal and external layers, wherein the materials comprise the following components in part by weight: 100 parts of polyvinyl chloride, 45 to 55 parts of fillers, 0.5 to 1 part of foaming agent, 5 to 10 parts of modified agent and 4 to 6 parts of aid. According to the polyvinyl chloride foamed internally and externally-crusted foaming pipe, foaming is uniform by the proportioning of the materials and the control of an extrusion process, so that a sound-insulating effect of the foaming pipe can be improved, the consumption of materials is reduced, and the cost is reduced.

100 parts of SE,
Filler 45-55 part,
Whipping agent 0.5-1 part,
Modification agent 5-10 part,
Auxiliary agent 4-6 part.
In preferred embodiment of the present invention, said material comprises by weight than the following composition of forming:
100 parts of SE,
50 parts of fillers,
0.8 part of whipping agent,
8 parts of modification agents,
5 parts of auxiliary agents.
In preferred embodiment of the present invention, said filler is a lime carbonate.
In preferred embodiment of the present invention, the board number of extruding that adopts during said forcing machine extrusion molding is 1.
In preferred embodiment of the present invention, the quench liquid that said quench liquid cool quickly adopts when forming the ectonexine skinning is a cooling oil, and the oil temperature is 40-50 ℃.
The invention has the beneficial effects as follows: the present invention has disclosed the inside and outside foam pipe of a kind of foam polyvinyl chloride, is applicable to occasions such as covil construction draining feedwater, industrial protection, agricultural drainage and irrigation, through the proportioning of material and the control of extrusion process; Be mainly: ectonexine all adopts polyvinyl-chloride foam material, adopts 1 forcing machine to extrude, and adopts oily temperature cool quickly method to form the ectonexine skinning; Technology is simple, is easy to control, makes foaming pipe uniform in foaming; Can improve sound insulation, the effect of heat insulation of foaming pipe; And can improve intensity, prolongs life reduces material and reduces cost.
