Problems solved by technology

[0002] Most of the traditional construction glues are liquid, such as 107, 801, 901 glue, etc. Most of these liquid glues contain harmful substances such as formaldehyde, which are not convenient for storage and transportation when used, and will also cause harm to people who produce, construct and use. Harmful, not conducive to health and polluting the environment

Embodiment 1

[0012] The following materials are taken by weight percentage: 30% of pregelatinized starch, 50% of cold water instant polyvinyl alcohol powder, and 20% of hydroxypropyl methylcellulose. During production, the above-mentioned components are directly mixed in proportion, stirred evenly, and packaged. During construction, 70 times of water is added, mixed and stirred evenly, and then used.

Embodiment 2

[0014] The following materials are taken by weight percentage: 50% of pregelatinized starch, 40% of cold water instant polyvinyl alcohol powder, and 10% of hydroxyethyl cellulose. During production, the above-mentioned components are directly mixed in proportion, stirred evenly, and packaged. During construction, 50 times of water is added, mixed and stirred evenly, and then used.

Embodiment 3

[0016] The following materials are taken by weight percentage: 40% of pregelatinized starch, 20% of cold water instant polyvinyl alcohol powder, 15% of hydroxyethyl cellulose, and 25% of redispersible latex powder. During production, the above-mentioned components are directly mixed in proportion, stirred evenly, and packaged. During construction, 40 times of water is added, mixed and stirred evenly, and then used.

Abstract

The invention relates to an adhesive for buildings, in particular to cold water fast dissolving rubber powder for buildings. The cold water fast dissolving rubber powder is characterized by mainly comprising the following substances in percentage by weight: 30-60 percent of pre-gelatinized starch, 15-50 percent of cold water fast dissolving polyvinyl alcohol powder and 10-40 percent of hydroxy ethyl cellulose or hydroxypropyl methyl cellulose. During production, the compositions are directly mixed proportionally, stirred uniformly, and packaged. During construction, 30-100 times of water is added for mixing and stirring uniformly. The cold water fast dissolving rubber powder has the advantages of low cost, environmental friendliness, fast dissolubility in cold water, easiness for constructing, high adhesion, increase in adhesion strength and smoothness, and convenience for storing and transporting, can be mixed with cement, talc powder, nature calcium carbonate, gypsum products, water-proof materials and the like or used separately, and has tackifying property and water retention property.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a water-soluble adhesive. Background technique [0002] Most of the traditional construction glues are liquid, such as 107, 801, 901 glue, etc. Most of these liquid glues contain harmful substances such as formaldehyde, which are not convenient for storage and transportation when used, and will also cause harm to people who produce, construct and use. Harmful, not conducive to health and pollute the environment. Contents of the invention [0003] The problem to be solved by the present invention is to provide an instant rubber powder that does not contain formaldehyde, is healthy and environmentally friendly, and has good workability and firmness. [0004] In order to solve the above problems, the invention provides a kind of cold water instant rubber powder for construction, which is characterized in that it mainly consists of the following substances in weight percentage: 3...
