Putty combination

Abstract

The invention belongs to the field of building materials and relates to a putty combination. The putty combination comprises the following raw materials in parts by weight: 10-15 parts of a copolymer powder, 30-50 parts of light clay brick, 10-15 parts of perlite, 6-9 parts of high-alumina cement, 12-18 parts of mullite, 10-15 parts of bentonite, 2-4 parts of camsellite, 1-3 parts of dextrin, 3-5 parts of methyl cellulose, 5-8 parts of a silica powder, 5-10 parts of bastose or viscose, 8-18 parts of sodium silicate, 1-4 parts of a lignocellulose aerogel liquid, 4-6 parts of a dispersible emulsion powder and 10-15 parts of compound suspension consisting of aluminum oxide sol and silicon dioxide sol by a ratio by mass of 1:1, wherein the copolymer powder is a modified polyethylene and polypropylene mixture; the lignocellulose aerogel liquid is prepared by a method comprising the steps of pulverizing, purifying, freeze-thawing and solidifying regeneration. The putty combination is excellent in adhesiveness and filling ability and can prevent the wall from discoloring and falling.

Description

technical field [0001] The invention belongs to the field of building materials and relates to a putty composition. Background technique [0002] At present, there are many kinds of putty compositions, mainly used for cement wall and concrete wall, with different strengths. When the putty composition is used to renovate some tile walls and mosaic walls, the putty has defects such as weak adhesion and poor water resistance; at the same time, it also has low fire protection rating, great dependence on the external wall structure and limited aesthetics , while achieving fire protection, it is impossible to pay attention to other important indicators such as heat preservation, waterproof, strength, and moisture absorption rate, and it is impossible to take into account the problems of long service life, low resource consumption, light environmental pollution, and light weight.

When the putty composition is used to renovate some tile walls and mosaic walls, the putty has defects such as weak adhesion and poor water resistance; at the same time, it also has low fire protection rating, great dependence on the external wall structure and limited aesthetics , while achieving fire protection, it is impossible to pay attention to other important indicators such as heat preservation, waterproof, strength, and moisture absorption rate, and it is impossible to take into account the problems of long service life, low resource consumption, light environmental pollution, and light weight.

[0003] CN101544856B (2012-9-26) discloses a putty composition, but its adhesion, filling, waterproof, strength, moisture absorption rate, and prevention of wall discoloration and peeling still need to be improved
