Embodiment Construction

[0020] 1. Raw material selection and processing:

[0021] 1. For expanded perlite, select expanded perlite particles with a particle size of 0.1-8mm.

[0022] 2. Volcanic tuff: crush the volcanic tuff, sieve it, and select sand grains with a particle size of 0.1-10mm.

[0023] 3. For aluminate early-strength cement, choose No. 325 aluminate early-strength cement.

[0024] 4. Polyvinyl formal, the polyvinyl formal particles are ground into a powder with a mesh size of less than 500.

[0025] 5. The mixture of saponin and sisal short fiber, cut the sisal leaves to about 10mm in length, put them into 40% caustic soda solution, add 10% vegetable or animal oil, cook, then concentrate and dry, Grinding becomes a powder containing saponin and fatty acid salt and sisal fiber.

[0026] 6. Organic silicon waterproofing agent, choose the water-soluble organic silicon waterproofing agent produced by the action of organic silicon and alkali.

[0027] 2. Preparation of thermal insulatio...

Abstract

The invention discloses a saponin-foamed and sisal fiber-enhanced wall body heat preservation mortar. The mortar is prepared by the steps of raw material selection, processing and preparation of heat preservation mortar. A finished product of the heat preservation mortar is prepared by mixing expanded perlite, volcanic tuff, aluminate early strength cement, polyvinyl formal, a mixture of saponin and short sisal fibers and an organic silicon water repellent in a mass ratio, stirring and performing waterproofing packing. Pores are generated by utilizing a foaming effect of the saponin; the strength of a heat preservation layer is improved by sisal toughening; mechanical strength is improved by utilizing the volcanic tuff; therefore, the heat preservation mortar of the invention has the advantages of low thermal conductivity, high strength, high bending resistance and impact resistance, and convenient production and use, and is applicable to the thermal insulation and the heat preservation of a building wall body.

Description

technical field [0001] The invention proposes a saponin foamed and sisal fiber reinforced wall thermal insulation mortar used for wall thermal insulation in the field of building materials. Background technique [0002] At present, wall insulation is inlaid with polystyrene foam boards on the outside of the wall, and then a mosaic type insulation body is formed by smearing a decorative surface layer on it. Due to the poor aging resistance of polystyrene, and it is easy to burn and produce toxic and harmful gases after being subjected to high temperature, it is restricted in general residential construction. [0003] There is also spraying and foaming polyurethane insulation layer on the existing body of wall to carry out thermal insulation. When carrying out construction, it is first necessary to make a base layer, then spray it, and then make a surface layer, so the construction process is complicated, and the cost is high. The wall insulation layer made is single in form,...
