Problems solved by technology

[0003] At present, most of the jointing agents are used after the decoration is completed to prevent dust from being stuck in the joints. However, the materials used in conventional jointing agents are not environmentally friendly and harmful to the human body. Therefore, an environmentally friendly jointing agent is urgently needed

Abstract

The invention relates to a preparation method of a crack sealer for construction. The preparation method includes the following steps: (1) weighing the following components, by weight: 2-5 parts of silica sand, 5-9 parts of slag powder, 5-9 parts of putty ash, 2-8 parts of polyvinyl acetate emulsion, 4-7 parts of heavy calcium powder, 3-9 parts of a polyurethane associative thickener, 1-4 parts ofhydroxypropyl methyl cellulose and 7-11 parts of cement; (2) placing the weighed silica sand and slag powder into an earth kiln to obtain a sintering material and keeping the sintering material for later use; (3) placing the sintering material into a crusher for crushing to obtain a crushed material; (4) stirring the crushed material and the weighed putty ash, polyvinyl acetate emulsion, heavy calcium powder, polyurethane associative thickener, hydroxypropyl methyl cellulose and cement to obtain a mixed material; and (5) adding the mixed material into a grinder for grinding to obtain the crack sealer for construction. The beneficial effects of the preparation method of the crack sealer for construction are that the crack sealer adsorbs harmful substances, effectively prevents mildew phenomenon, keeps mold seams from being moldy, and has environmental protection effects.

Description

Technical field [0001] The invention relates to the field of building materials, in particular to a method for preparing a jointing agent for building. Background technique [0002] Tile jointing agent is also known as face tile jointing agent. This material is made of cement, quartz sand, pigment filling and a variety of additives which are uniformly mixed mechanically. Tile jointing agent is mainly used as jointing agent between ceramic tiles and face tiles. [0003] At present, most of the jointing agents are jointed after the decoration is completed to prevent dust from getting stuck in the joints. However, the materials used in conventional jointing agents are not environmentally friendly and harmful to the human body. Therefore, an environmentally friendly jointing agent is urgently needed. Summary of the invention [0004] In summary, in order to overcome the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a method for ...
