Problems solved by technology

EPS, XPS, and PU are all organic thermal insulation materials. The biggest advantage is light weight, heat preservation, and good heat insulation; the biggest defect is fire prevention, poor safety, easy aging, easy to burn, large smoke, high toxicity, and low load-bearing capacity when burning. , service life, and fire resistance are not as good as inorganic insulation materials

Abstract

The invention discloses a high-cold-resistant waterproof composite board material and a preparation method thereof. The high-cold-resistant waterproof composite board material is prepared from the following raw materials in parts by weight: 30-50 parts of polystyrene, 10-15 parts of polycarbonate, 5-10 parts of absolute ethanol, 8-15 parts of bentonite, 12-15 parts of organosilicone-modified epoxyresin, 12-18 parts of silicon dioxide, 15-25 parts of styrene-butadiene latex, 4-9 parts of bamboo powder, 10-20 parts of dimethyl silicon oil, 2-10 parts of carbon fibers, 1-8 parts of glass fibers,11-17 parts of zinc stearate and 2-8 parts of diatomite. The high-cold-resistant waterproof composite board material is simple in preparation process and low in cost, and the prepared high-cold-resistant waterproof composite board material has the advantages of low capacity, waterproofness and good heat insulation effect and is strong in chemical stability, nontoxic and odorless so as to be an ideal heat insulation material.

Description
