Embodiment 1

[0012] The following materials are taken by weight percentage: 30% of cold water instant polyvinyl alcohol powder, 5% of polyacrylamide, and 65% of hydroxyethyl cellulose. During production, the above-mentioned components are directly mixed in proportion, stirred evenly, and packaged. During construction, 80 times of water is added, mixed and stirred evenly, and then used.

Embodiment 2

[0014] The following materials are taken by weight percentage: 60% of cold water instant polyvinyl alcohol powder, 10% of polyacrylamide, and 30% of hydroxypropyl methylcellulose. During production, the above-mentioned components are directly mixed in proportion, stirred evenly, and packaged. During construction, 200 times of water is added, mixed and stirred evenly, and then used.

Embodiment 3

[0016] The following materials are taken by weight percentage: 44% of cold water instant polyvinyl alcohol powder, 1% of polyacrylamide, 40% of hydroxyethyl cellulose, and 15% of redispersible latex powder. During production, the above-mentioned components are directly mixed in proportion, stirred evenly, and packaged. During construction, 150 times of water is added, mixed and stirred evenly, and then used.

Abstract

The invention relates to binder for construction and discloses a high-polymer instant-dissolving environment-friendly binder power. The high-polymer instant-dissolving environment-friendly binder powder is characterized by including, by weight percentage, 20-75% of cold water instantly-dissolving type polyvinyl alcohol powder, 0.5-15% of polyacrylamide and 15-70% of hydroxyethyl cellulose or hydroxypropyl methyl cellulose. During production, the above raw materials are mixed and stirred uniformly directly according to proportion and packaged to form the high-polymer instantly-dissolving environment-friendly binder powder. The high-polymer instantly-dissolving environment-friendly binder powder has the advantages of low cost, environment protection, quick dissolving by cold water, easiness in construction, high binding performance, capability of preventing cracking and shedding of a plaster layer, improved binding strength and smoothness and convenience in storage and transport, and further, is mainly applicable to being used as binder, filmogen, flatting agent and humectants in construction coating and inner-wall or outer-wall putty, or can be used with cement, talcum powder, putty powder, gray calcium powder, plaster products, waterproof materials and the like or can be used independently and has high improved binding performance and water-retaining property.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a building adhesive. Background technique [0002] At present, most construction glues on the market are liquid and contain harmful substances such as formaldehyde. When used, they are not convenient for storage and transportation, but also cause harm to the human body and pollute the environment, which is not conducive to health or environmental protection. Contents of the invention [0003] The problem to be solved by the present invention is to provide a formaldehyde-free, healthy and environmentally friendly polymer instant rubber powder with good workability and firmness. [0004] In order to solve the above problems, the present invention provides a kind of polymer instant environmental protection rubber powder, which is characterized in that it is mainly composed of the following substances by weight percentage: cold water instant polyvinyl alcohol powder 20% ~ 75%, pol...
