Problems solved by technology

[0003] At present, there are many wall insulation products in the construction market. One is board, such as cement polystyrene board, gypsum polystyrene board, GRC board, etc., but it takes up a lot of indoor space and is prone to cracks.
Our company introduced NPS composite thermal insulation material in 2001. It is a slurry material made of sepiolite, asbestos, perlite plus reinforcing agent, binder and water. There are disadvantages such as unstable quality, difficult packaging and transportation, difficult storage, expensive raw materials, etc.

example 1

[0023] Take 110 parts of sepiolite powder, 44 parts of perlite, 35 parts of white clay and 12 parts of cellulose by weight.

[0024] Stir the sepiolite, white clay, and cellulose in a mixer for 5 minutes, then add perlite and stir for 2 to 3 minutes. When using, add two parts of water to one part of dry powder by weight, and it will form a mortar after mixing, which can be directly applied to the wall.

example 2

[0026] 105 parts of sepiolite powder, 45 parts of perlite, 33 parts of white clay, 14 parts of cellulose, the processing method is as above example.

example 3

[0028] 115 parts of sepiolite powder, 45 parts of perlite, 32 parts of clay, 15 parts of cellulose, the processing method is as above example.

Abstract

A composite insulating material for wall is prepared from sepiolite powder, pearlite, argil and cellulose through p roportioning, sequential mixing, and stirring. Its advantages are no efforescence, no pollution and low cost.

Description

technical field [0001] The invention relates to a building wall thermal insulation material, which is mainly used for internal thermal insulation of building exterior walls and roof thermal insulation. Background technique [0002] Our country attaches great importance to building energy conservation, and it is mandatory that the building energy conservation rate is not less than 50%. According to relevant data, the energy loss caused by wall heat transfer is about 1 / 3 of the total energy consumption of buildings. Therefore, wall insulation is an important part of building energy conservation. [0003] At present, there are many wall insulation products on the construction market. One is boards, such as cement polystyrene boards, gypsum polystyrene boards, and GRC boards, but they take up a lot of indoor space and are prone to cracks. Our company introduced NPS composite thermal insulation material in 2001. It is a slurry material made of sepiolite, asbestos, perlite plus r...
