Description
Technical field
The present invention is specifically related to a kind of plastic extrusion composite membrane subsidiary engine and manufactures the method for composite plastic woven cloth, belongs to plastic products processing technique field.
Background technology
Composite plastic woven cloth has had the time of decades in the production of China, and the raw material used mainly contain polypropylene, polyethylene and ethylene-vinyl acetate copolymer.Its production technology and technology are very ripe, and its technological process of production is that polypropylene or low-pressure polyethylene are extruded into film on wire drawing machine, becomes flat filament, after adding hot-stretch, heat treatment shaping, be coiled into an ingot with intensive blade cutting.Flat filament as circular weaving machine, water loom or gripper shuttle loom etc. are woven into plastic woven cloth through loom, then are coated with in the one or both sides curtain coating of plastic woven cloth through plastic extrusion compounding machine and are covered with polypropylene or the macromolecular material such as polyethylene from high pressure process or ethylene-vinyl acetate copolymer forms.
Composite plastic woven cloth has the advantages such as waterproof, nontoxic, light weight, resistance to low temperature are good, easy to be recycled, and widely, in the past, it was mainly used in a lot of aspect such as seepage by geo-textile, tent, colour bar cloth, tarpaulin, hot house, aquaculture in application.Along with the enhancing of mankind's environmental consciousness, people are just making great efforts to develop its new purposes, as roofing insulation, PE advertising cloth, electric heat mat lining, vegetable booth thermal insulation quilt etc., make full use of its advantage and substitute original non-environment-friendly products.In the process of exploitation, it is found that the composite plastic woven cloth of conventional production equipment and explained hereafter exists following shortcoming: percent thermal shrinkage is high, surface evening degree is poor.Through Exposure to Sunlight or hot-working, composite plastic woven cloth can be out of shape, and wrinkling or surface does not flatten, or size diminishes because of contraction, is so just difficult to meet the serviceability requirement of new opplication field to product.Cause that composite plastic woven cloth percent thermal shrinkage is high, the main cause of surface evening degree difference is the production procedure of composite plastic woven cloth in (i.e. wire drawing, weave cotton cloth, compound), the deficiency of legacy equipment, technique and the feature of woven cloth own.Such as, the thermal finalization treating apparatus that traditional wire drawing machine is produced in flat filament process is too simple, cause that flat filament heats in thermal finalization processing procedure, inhomogeneous cooling is even, insufficient, flat filament macromolecular chain molecularly oriented, crystallization are inconsistent, internal stress is eliminated insufficient, thus causes flat filament percent thermal shrinkage high and uneven; Loom let off motion of weaving cotton cloth cannot ensure that warp tension is consistent; Above two reasons cause plastic woven cloth percent thermal shrinkage high and uneven.Because plastic woven cloth major part is Longitude-latitude ten font weaving, there is gap between flat filament, after causing compound, cloth cover is uneven, and grammes per square metre is more heavily more obvious, and the problems referred to above that the woven cloth that flat filament folds weave exists are more outstanding.
In sum, for the deficiency that composite plastic woven cloth in prior art exists, and the defect that the production process of composite plastic woven cloth exists, the invention provides a kind of low heat shrinkage, the plastic extrusion composite membrane subsidiary engine of high surface evening degree and the method for manufacture composite plastic woven cloth thereof.
