Problems solved by technology

[0002] With the improvement of people's cultural living standards, the demand for environmentally friendly and non-toxic decorative materials is gradually increasing, and the original materials are becoming less and less suitable for people's needs. The market needs new high-tech materials to replace old materials, and the insulation market is also growing. Similarly, the original wall insulation materials have the following disadvantages: secondary pollution caused by toxic and non-degradable inorganic materials, cumbersome construction, high unit cost, no fire resistance, no high temperature resistance, no acid and alkali resistance, and no corrosion resistance. Its surface is used as solvent-based coating
In the technical field of thermal insulation putty, the applicant has not found any similar or related technical solutions after searching.

preparation example Construction

[0048] The preparation process of the invention is as follows: mixing the base material, the filler and the auxiliary agent according to a certain weight ratio, stirring evenly, and measuring and packaging. The construction method is: the base layer should meet the following requirements before construction: smooth, no oil, no powder, no hollowing, cracks, floating ash, no obvious unevenness, according to the ratio of putty and water as 1:0.4 and stir it into a paste After the paste is formed, scrape in batches, and the thickness is controlled between 2mm-3mm. After the first pass is dried, scrape in batches for the second time. Use as much as you want each time. The prepared putty should be used up within 2-3 hours.

[0049] The performance index of the present invention is as follows: according to (putty for building exterior wall) (JG / T157-2004) national standard putty performance is detected, and the results are shown in Table 4 (putty detection result for building exterior...

Abstract

This invention discloses heat-insulating putty for interior and exterior walls of buildings. The heat-insulating putty is composed of matrix, filler and additive. The matrix is composed of redispersible latex powder and Portland cement at a weight ratio of (4-6) :( 5-7). The filler is composed of hollow microbeads, expanded perlite, ash calcium powder and talcum powder at a weight ratio of (1-2) :( 1-2) :( 0.5-1) :( 0.5-1.5). The additive is composed of hydroxymethyl propyl cellulose, polypropylene fibers and silica micropowder at a weight ratio of (1-3) :( 0.1-1) :( 40-60). The heat-insulating putty is prepared by mixing the matrix, the filler and the additive at a weight ratio of (20-60) :( 40-80) :( 3-10), stirring uniformly, weighing and packaging. The heat-insulating putty is environmentally friendly, and can be used on interior and exterior walls of buildings. The heat-insulating putty has such advantages as high heat-insulating performance, low heat conductivity, high acid, alkali and corrosion resistance, simple and reasonable preparation method, and easy construction.
