Seam crack-resisting putty

Abstract

The invention discloses a seam crack-resisting putty and aims at solving the problems that the existing similar seam crack-resisting putties have complex process, high cost, poor surface flatness after filling, repairing or finishing, and difficult polishing and finishing, and can not be applicable to wood or metal wall surfaces, table surfaces, furniture and other objects. The seam crack-resisting putty is characterized by being formed by the uniform mixing of a paste-shaped main agent and an auxiliary agent with the weight ratio of 1:0.5 to 2, wherein the main agent contains 63 to 84 percent of epoxy resin and 16 to 37 percent of plant powder with the particle size of less than 1 mm in percentage by weight. The auxiliary agent contains 63 to 84 percent of epoxy resin curing agent and 16 to 37 percent of plant powder with the particle size less than 1 mm in percentage by weight. 0.8 to 17 percent of toner can also be added to the main agent and the auxiliary agent in percentage by weight; and in percentage by weight the toner can be formed by uniform mixing of 1 to 99 percent of pigment powder and 1 to 99 percent of lithopone, titanium dioxide, talc powder, kaolin or bentonite, and the like.

Description
