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

Abstract

The invention discloses a modified polyurethane thermal-insulation composite board. The composite board sequentially comprises a gypsum board layer, a thermal-insulation board layer and a cement board layer from inside to outside, wherein the thermal-insulation board layer is prepared from modified polyurethane, acrylate, diisocyanate, an alkyd resin, dipropylene glycol monobutyl ether, an organic silicon resin, a melamine formaldehyde resin, chlorinated paraffin, diisocyanate, nitrocellulose, glass fibers, nano calcium carbonate, perlite, fly ash, magnesium oxide, n-octanol, lauryl alcohol, hexadecanol, polymer dibasic alcohol, fluorine-containing polyether dibasic alcohol, a compatilizer, an emulsifier, a foaming agent, a silane coupling agent, a curing agent and silicone oil. The modified polyurethane thermal-insulation composite board has excellent thermal insulation property and excellent heat resistance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a 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. The weather resistance of the ...
