Problems solved by technology

[0002] At present, most of the internal and external walls of building envelopes in my country still use ordinary cement mortar that has been used for many years. The thermal conductivity of this ordinary cement mortar layer is very high, and the function of preventing heat transfer is very poor. Areas with large temperature differences often consume a lot of energy due to frequent heat exchange between hot and cold air
In order to solve the above problems, people try to add a certain amount of polystyrene or other plastic material particles to the ordinary cement mortar, hoping to meet the requirements of the wall surface, especially the external wall surface, through the heat resistance characteristics of the polystyrene or plastic particles. thermal insulation requirements, but this improved wall mortar material still has the following defects: First, the density of the mortar sheath is still too high

Example Embodiment

[0009] The wall thermal insulation material provided in Example 1 is composed of 50% of base material, 22% of expanded perlite, 11% of Portland cement, 14% of polyvinyl alcohol glue, and 1.0% of carboxymethyl by weight. Consisting of cellulose, 1.85% sodium bentonite and 0.15% polypropylene fibers.

Example Embodiment

[0010] The wall thermal insulation material provided in Example 2 is composed of 52% of base material, 20% of expanded perlite, 10% of Portland cement, 15% of polyvinyl alcohol glue, 1.0% of carboxymethyl by weight. Consisting of cellulose, 1.85% sodium bentonite and 0.15% polypropylene fibers.

Example Embodiment

[0011] The wall thermal insulation material provided in Example 3 is composed of 55% of base material, 18% of expanded perlite, 12% of Portland cement, 12% of polyvinyl alcohol glue, 1.0% of carboxymethyl by weight. Consisting of cellulose, 1.85% sodium bentonite and 0.15% polypropylene fibers.

[0012] In the above-mentioned embodiments, the base material is the light calcium carbonate loose powder with a layer of stearic acid wrapped on the outside, and it is composed of the light calcium carbonate powder of 94~96% by weight and the stearic acid of 4~6% by weight, After hot mixing for 2 to 3 hours at a temperature of 105 to 150° C., it is formed by natural cooling. Light calcium carbonate powder should meet the requirements of national chemical industry standard HG2226-91, and the purity of stearic acid should not be less than 98%. This base material is the most critical component in the material of the present invention, and its quality will have a fundamental impact on th...

Abstract

An insulating material for wall surface is prepared from the basic material which is light calcium carbonate particles coated by stearic acid, expanded pearlite, silicate cement, polyvinyl alcohol adhesive, carboxymethyl cellulose, Na-base bentone and polypropylene fibres. Its advantages are high mechanical performance, less deformation and high insulating effect.

Description

technical field [0001] The invention relates to an energy-saving building material, in particular to a wall heat insulation material mainly used for the inner and outer sides of building enclosure structures. Background technique [0002] At present, most of the internal and external walls of building envelopes in my country still use ordinary cement mortar that has been used for many years. The thermal conductivity of this ordinary cement mortar layer is very high, and the function of preventing heat transfer is very poor. Areas with large temperature differences often consume a lot of energy due to frequent heat exchange between hot and cold air. In order to solve the above problems, people try to add a certain amount of polystyrene or other plastic material particles to the ordinary cement mortar, hoping to meet the requirements of the wall surface, especially the external wall surface, through the heat resistance characteristics of the polystyrene or pl...
