Embodiment 1

[0019] A. Raw material components and proportions of plastic hollow shapes: (by weight) calculus powder 60

[0020] PVC 30

[0021] Auxiliary 10

[0022] The additives are composed according to the following raw material components and proportions: (parts by weight) chlorinated paraffin 0.6, barium stearate 0.6, lead stearate 0.6, dioctyl phthalate 13, dibutyl phthalate 1.2, chlorinated polyethylene 0.4, tri-salt 2.4, di-salt 0.8, stearic acid 2.

[0023] B. Manufacturing method: mix the raw materials of calculus powder, polyvinyl chloride, and additives according to the ratio and then knead them in a kneader. The kneading temperature is 110-120°C, and the kneading time is 30-35 minutes; The granulator extrudes pellets under high temperature at 170-180°C and high pressure; then put the pellets into the extruder at an extrusion temperature of 175-210°C, and extrude plastic holl...

Abstract

A heat-insulating shaped plate for building is composed of the hollow plastic section with internal reinforcing ribs, and foam polyurethane plastics as filler which is filled in the said hollow plastic section. Its advantages are high strength, high resistance to corrosion, cold and fire, simple structure, low cost and long service life.

Description

technical field [0001] The invention relates to the improvement of building decoration boards, belonging to building decoration materials. Background technique [0002] Existing construction projects widely use a class of boards for thermal insulation walls, most of which are made of iron plates, color steel plates, etc. as panels, with perlite, slag, rock wool, etc. as core materials, which are bonded and compounded. There are different degrees of deficiencies such as low structure density, low strength, poor corrosion resistance, cold resistance and flame retardancy, complicated installation process, and short service life. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned shortcomings, and provide a new type of insulation board, special-shaped material and its manufacturing method with high strength, good corrosion resistance, cold resistance and flame retardant performance, easy installation and ...
