Problems solved by technology

But the construction glue powder (solid glue) of prior art, except that its adhesion ability is different, also generally has the shortcoming of polluting the environment, and some long-term contact can cause damage to the health of construction workers.

Embodiment Construction

[0029] A kind of high temperature resistant glue powder is made up of following components, and the parts by weight of each component are:

[0030] Lightweight nano calcium carbonate 50-70

[0031] Aluminum silicate ceramic fiber 10-15

[0032] Ethylene / vinyl acetate copolymer rubber powder 4-7

[0033] Fly Ash 5-10

[0034] Acrylamide 10-15

[0035] Calcium formate 1-2

[0036] Polycarboxylate high performance water reducer 1 -2

[0037] Lignin 1-2

[0038] Silyl Hydrophobic Agent 4-6

[0039] Attapulgite 3-5

Abstract

The invention discloses a high temperature resistant glue powder comprising the following components in parts by weight: 50-70 parts of light nanometer calcium carbonate, 10-15 parts of alumina-silicate ceramic fibres, 4-7 parts of ethylene/vinyl acetate copolymer adhesive powder, 5-10 parts of pulverized fuel ash, 10-15 parts of polyacrylamide, 1-2 parts of calcium formate, 1-2 parts of polycarboxylates high performance water-reducing admixture, 1-2 parts of lignin, 4-6 parts of silicon alkyl water repellent, 3-5 parts of attapulgite, 1-3 parts of titanium white and 3-5 parts of nanometer silicon dioxide. A preparation method of the high temperature resistant glue powder comprises the following steps of: with the nanometer light calcium carbonate as a carrier, mixing the alumina-silicate ceramic fibres, the ethylene/vinyl acetate copolymer adhesive powder, the calcium formate, the water-reducing admixture, the water repellent, the lignin, the polyacrylamide, the pulverized fuel ash and the like together to prepare a white powder. The glue powder disclosed by the invention has the characteristics of no toxicity, no pollution, odorlessness, zero radioactivity and no alkalinity, and has a wide range of applicable temperatures. Coatings prepared by the high temperature resistant glue powder have the advantages of convenience for construction, good flatting property and quickness in film forming, and neither drip like a urine line nor roll up on surfaces.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a high temperature resistant glue powder. Background technique [0002] The glue used in the construction industry is different from ordinary glue, which requires high adhesion and a long enough sticky time. There are two production methods for construction glue currently used in the market. One is that the manufacturer directly packs the liquid produced by chemical materials such as polyvinyl alcohol and acrylamide and puts it on the market; the other is that the manufacturer puts PVA, EVA, CMC, etc. High molecular polymer rubber powder is processed into construction glue and put on the market after packaging. The packaging required by these two production methods is large and not energy-saving enough; the cost of storage and transportation on the market is high and not economical; the products produced are inconvenient to use; the glue produced by them contains toxic sub...
