Embodiment Construction

[0019] Prepare the ingredients according to the weight ratio in Table 1.

[0020] The weight proportion of table 1 embodiment 1~embodiment 3

[0021]

[0022]

[0023] The particle size of the above-mentioned closed-cell expanded perlite is 150-200 μm.

[0024] The particle size of the aforementioned titanium dioxide is 100 to 2000 nm.

[0025] The above-mentioned redispersible latex powder is an ethylene-vinyl acetate copolymer polymer.

Abstract

The invention provides a cement-based thermal insulation material, which belongs to the technical fields of building materials. The cement-based thermal insulation material comprises, by weight, 20 to 30 parts of Portland cement, 3 to 7 parts of polystyrene particles, 5 to 15 parts of fly ash, 1 part of polyaluminum chloride, 3 to 5 parts of silica powder, 20 to 30 parts of aluminate refractory cement, 5 to 15 parts of the polyacrylonitrile-based carbon fibers, 5 to 15 parts of carbon fibers, 1 to 2 parts of titanium dioxide, 1 to 2 parts of sodium fluosilicate, 3 to 5 parts of closed-cell expanded perlite, 5 to 10 parts of redispersible latex powder, 1 part of cellulose ether, 1 part of a water reducer, 1 to 5 parts of calcined desulfurization gypsum powder, 1 to 5 parts of quartz powder, 3 to 5 parts of gray calcium, 3 to 5 parts of heavy calcium, 3 to 5 parts of alumina silicate fibers, 1 to 2 parts of oil shale particles and 1 to 2 parts of bentonite. The cement-based thermal insulation material provided by the invention has the advantages of easily available raw materials and a good thermal insulation effect.

Description

technical field [0001] The invention provides a cement-based thermal insulation material, which belongs to the technical field of building materials. Background technique [0002] At present, due to climate change, extreme cold or extreme heat has appeared in many areas. It is necessary to turn on the heating or cooling air-conditioning system in the building to satisfy people's comfortable living temperature, but this is likely to cause high energy consumption, which is very Uneconomical. With the rapid development of my country's economy, coal, electricity and transportation capacity are increasingly in short supply, saving energy and protecting the environment has become one of my country's basic national policies. Among all kinds of energy consumption, building energy consumption has the largest proportion and the fastest growth rate, accounting for 27.8% of the country's total energy consumption. [0003] Building thermal insulation is the largest application field of...
