Abstract

The invention relates to a preventive 650 flexible putty and a preparation method thereof, wherein the flexible putty comprises the following components and contents (wt%): 20-25 of water, 10-15 of styrene-acrylate emulsion, 0.4-0.6 of antifoaming agent, 22-25 of calcium carbonate, 38-42 of talcum powder and 1-2 of thickening agent. Compared with the prior art, the invention has the following advantages that: (1) the invention has good bonding strength when being bonded with various materials, higher compression resistance, bending resistance and pull-off strength as well as anti-permeability and waterproofness; (2) the preventive 650 flexible putty has flexibility after solidification, can correct the microdeformation of buildings and small cracks on wall surfaces, and reduces the influence of base materials on coating to the maximum extent; (3) the preventive 650 flexible putty is innoxious, tasteless and non-combustible, and has strong preventive performance; and (4) the preventive 650 flexible putty facilitates the construction, and has good durability and moderate price.

Description

technical field [0001] The invention relates to putty, in particular to a Fangbao 650 elastic putty and a preparation method thereof. Background technique [0002] On the interior and exterior walls that have been coated with architectural paint, it is often found that the surface of the wall is rough, uneven, cracked, peeled and peeled off. Tortoise cracks cause water seepage on the back surface of the coating, which causes the coating to peel and fall off, and even affect the function and appearance of the building. Contents of the invention [0003] The object of the present invention is to provide a Fangbao 650 elastic putty with excellent performance and convenient construction and a preparation method thereof in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A kind of anti-protection 650 elastic putty is characterized in that, the elast...
