Preparation method of macromolecular synthesized building mold plate

Abstract

The invention discloses a preparation method of a macromolecular synthesized building mold plate. The preparation method is characterized by comprising the steps: pouring different main materials and additives according to a given ratio into a mixer hopper; pumping the mixture into a high-speed mixing pot at a normal temperature, stirring at a high speed and heating; placing the mixture into a low-speed stirring pot after reaching a set temperature, stirring at a low speed and cooling; pumping the mixture into a host machine hopper through a main machine spiral loading machine; feeding the material into a barrel after each area of the barrel is heated to a set temperature; thermally smelting the material through the barrel, squeezing the material through a screw, and extruding the material through a machine head; introducing the material into a traction machine through a traction rope; shaping the material through a shaping mold; cooling the material through a support frame; determining the width of the mold plate through a longitudinal cutting saw; determining the length of the mold plate through a transverse cutting saw; and packaging and warehousing the mold plate after inspection. The preparation method has advantages that the prepared macromolecular synthesized building mold plate has excellent physical mechanical property, is water-proof, damp-proof, low in water absorption rate, acid/alkali-resisting, corrosion-resisting, high in surface hardness, impact-resisting, good in manufacturability, capable of being nailed, planed, sawed and drilled, has a smooth surface, does not need a stripping agent, is environment-friendly, pollution-free, and has a good demolding effect and the leftovers after the mold plate is used on a construction site.

Description

Technical field [0001] The present invention involves a method of preparation of templates, especially a preparation method for polymer synthetic building templates. Background technique [0002] At present, there is a three -layer co -squeezed PVC plastic wood knot foam template, which is composed of upper hard knot cortex, foaming core layer, and lower hard cortex layer.This product is completed by the two extruders at the same time, and the upper hardcat cortex and the lower hard knot cortex are squeezed out by a PVC resin hot melt with a pvc resin, which is attached to the middle foaming layer at high temperature to improveSurface hardness and strength; the middle bubble layer is squeezed out by another extruder with a PVC resin, filling charging, and auxiliary agent through the hot melt. The middle foam core layer is mainly used to reduce weight and reduce costs.The main disadvantage of this product is: large equipment investment and high labor costs -the product is complete...
