Problems solved by technology

Rock wool is thermal insulation but absorbs water, which poses a safety hazard; polyurethane is not strong enough and cannot be used in large areas; foam glass, perlite, composite silicate, sepiolite, and external wall insulation mortar composited with organic silicon have high thermal conductivity, which cannot meet the requirements The thermal insulation effect, for a while, there is really no product in the thermal insulation market that can not only achieve the specified thermal insulation effect but also achieve Class A flame retardant

Abstract

The invention discloses a compound heat-insulating plate which comprises the following raw materials by weight parts: 55 to 65 parts of white cement 42.5R, 0.3 to 1 part of latex powder DA-1420, 5 to 10 parts of hydroxypropyl methyl cellulose 40US, 20 to 30 parts of ash calcium powder, 1.5 to 2.5 parts of wood fibers, 1.5 to 2.5 parts of bentonite, 2 to 2.5 parts of polyphenyl grains and 25 to 40parts of water. The polystyrene foam grains with low coefficient of heat conductivity are wrapped and stuck by non-flammable inorganic materials and then are processed according to a certain process,thereby forming the compound heat-insulating plate. The compound heat-insulating plate is A-level anti-flaming and the implementing technology is simple.

Description

technical field [0001] The invention relates to a thermal insulation board, in particular to a thermal insulation composite board and a preparation method thereof. Background technique [0002] The promotion and application of building energy-saving wall insulation technology and products in my country started in the mid-1980s. At that time, products such as perlite, composite silicate, sepiolite and external wall insulation mortar compounded with organic silicon were mainly promoted. In the early stage of wall insulation and energy saving, these products occupy a large market. In 1996, my country promulgated the second-step energy saving standard of 50%. With the improvement of energy-saving standards, the performance indicators of the above products have been difficult to meet the standard requirements. Around 2000, the above-mentioned products gradually withdrew from the building energy-saving market in the northern region. [0003] After years of development, my countr...
