Heat-proof insect preventing modified polyurethane thermal insulation composite board

Abstract

The invention discloses a heat-proof insect preventing modified polyurethane thermal insulation composite board which comprises a gypsum board layer, a thermal insulation board layer and a cement board layer sequentially arranged from inside to outside, wherein the thermal insulation board layer is prepared from the following raw materials: modified polyurethane, a styrene-acrylic emulsion, acrylate, polyvinylidene fluoride resin, organic silicon resin, microlite, light calcium carbonate, kieselguhr, chlorinated paraffin, talc powder, zeolite, titanium dioxide, talc powder, cellulose powder, magnesium oxide, nano calcium carbonate, mica powder, glass fiber, carbon cellulose, quicklime, quartz sand, active carbon, sodium dichloroisocyanurat, potassium sodium tartrate, fumaric acid, glutamine, inulin, borneol, trioctyl acetylcitrate, petroleum sodium sulfonate, sodium lauroyl glutamate, silicone oil, styrene, methyl triethoxy silane, a thickening agent, a silane coupling agent and a foaming agent. The heat-proof insect preventing modified polyurethane thermal insulation composite board disclosed by the invention has excellent heat resistance and insect preventing property.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a heat-resistant and insect-proof modified polyurethane thermal insulation composite board. Background technique [0002] Building energy consumption has always been the focus of our country's attention. Energy conservation and emission reduction has become a basic national policy that our country pays attention to. As a country with large energy consumption, since the late 1980s, my country has gradually implemented energy conservation measures of 30%, 50% and 65%. Three energy-saving work steps, and began to carry out beneficial attempts to implement higher energy-saving indicators in cities with conditions. With the gradual implementation of the goal of 65% energy saving in domestic buildings, polyurethane has great potential. [0003] However, the polyurethane composite panels currently on the market are generally bonded with polyurethane using an interface agent and mortar....

AI Technical Summary

Problems solved by technology

The weather resistance of the composite board is not good, and after a period of weather resistance, it will fall off or crack, deform, etc., which will bring hidden dangers to the safety of the external wall insulation system

Moreover, the comprehensive performance and production efficiency of ordinary polyurethane are not enough to meet the increasing market demand
