Problems solved by technology

[0005] The wall materials used in the building materials market, such as autoclaved aerated bricks, lime sand bricks, cement bricks, etc., generally have problems such as poor heat insulation, poor waterproof effect, and low strength of wall materials, while shale bricks and red bricks etc. need to be sintered, there are problems of energy saving and environmental protection
Most of the current foam concrete materials also have problems of poor waterproofing and poor strength, which urgently need to be improved.

[0055] The present invention also provides a method for preparing a self-insulating wall material, comprising the following steps:

[0056] a) After mixing and beating the base material, the waterproof enhancer described in any one of the above technical solutions and water, the first prefabricated slurry is obtained;

[0057] Or after mixing one or both of the matrix material, polypropylene fiber and filler, the waterproof enhancer described in any one of the above technical solutions and water for beating, the second prefabricated slurry is obtained;

[0058] b) mixing the first prefabricated slurry or the second prefabricated slurry obtained in the above steps, ceramsite and foaming agent, and then pouring and molding to obtain a green body;

[0059] c) After natural curing of the body obtained in the above steps, a self-insulating wall material is obtained.

[0060] The selection range and optimization principles of the raw materials in the present invention are consisten...

Embodiment 1

[0072] First weighed by mass fraction, 100 parts of cement, 0.1 part of polypropylene fiber, 10 parts of fly ash, 50 parts of tailings sand, 3 parts of waterproof reinforcing agent and 40 parts of water were evenly beaten to obtain prefabricated cement slurry; wherein, The specific formula of the waterproof enhancer is 40 parts by weight of polyvinyl alcohol aqueous solution, 30 parts by weight of methyl cellulose aqueous solution, 2 parts by weight of triethanolamine, 3 parts by weight of sodium methyl silicate, 7 parts by weight of polyacrylamide and 8 parts by weight. The coconut oil fatty acid diethanolamide of weight part.

[0073] At the same time, the ceramsite is subjected to anti-water absorption pretreatment, and the ceramsite is soaked in 801 construction glue, then taken out, and the glue is filtered off.

[0074] Then the obtained prefabricated cement slurry and foaming agent are mixed and stirred at a weight ratio of 1:0.03 to obtain a composite slurry, and then ...

Abstract

The invention provides a self-heat-insulation wall material. The self-heat-insulation wall material comprises, by weight, 30-40 parts of base materials, 0-0.5 part of polypropylene fibers, 0-60 parts of fillers, 2-8 parts of waterproofing and reinforcing agents, 1-8 parts of foaming agents, 10-30 parts of ceramsite and 9-20 parts of water. The self-heat-insulation wall material has the advantages that heat-insulation waterproofing and reinforcing for the self-heat-insulation wall material with the waterproofing and reinforcing agents are designed by means of adding special auxiliaries into the base materials, and the base materials, the special auxiliaries, the foaming agents and the ceramsite are jointly blended to obtain the novel light, heat-insulation and waterproof self-heat-insulation wall material; excellent waterproof structures can be particularly formed by the aid of the specific waterproofing and reinforcing agents and the ceramsite, and accordingly the self-heat-insulation wall material is excellent in waterproof performance and heat-insulation characteristic and high in strength.

Description

technical field [0001] The invention belongs to the technical field of building energy conservation, and in particular relates to a ceramsite composite self-insulating wall material and a preparation method thereof. Background technique [0002] With the continuous improvement of people's quality of life and urbanization, the requirements for building housing are also increasing. In the process of large-scale urbanization, building energy conservation has become an important issue in the implementation of low-carbon economy and sustainable development in cities and towns, and has been recognized. Highly valued from national to local. [0003] Building energy conservation, initially to reduce energy loss in buildings, is generally called "improving energy utilization in buildings". Under the condition of ensuring the comfort of buildings, energy is used rationally and energy utilization efficiency is continuously improved. Building energy conservation specifically refers to ...
