Adhesive for building board joint processed from waste stone

Abstract

The invention belongs to the technical field of building processing, and relates to an adhesive for a building board joint processed from waste stone. The adhesive comprises the following raw materials in parts by mass: 10-60 parts of calcium powder; 10-60 parts of silicon powder; 8-40 parts of redispersible latex powder; 15-30 parts of polymer rubber powder; 8-15 parts of hollow ceramic microbeads; 2-10 parts of modified starch; 0.2 to 3 parts of a cross-linking agent; 0.2 to 3 parts of a catalyst; 0.2-3 parts of a curing agent; 0.2 to 1 part of an accelerant; wherein the source of the calcium powder is marble crushed aggregates, and the source of the silicon powder is granite crushed aggregates. According to the adhesive, through combination of multiple component raw materials, industrial crushed aggregates are effectively utilized while the bonding strength and waterproofness are guaranteed, a better vertical face effect is formed by the adhesive and the microcrystal foaming heat preservation plates, and the adhesive is specially used for bonding the microcrystal foaming heat preservation plates.

Description

technical field [0001] The invention belongs to the technical field of building processing, and relates to an adhesive for joints of building boards processed by using waste stones. Background technique [0002] Nowadays, microcrystalline foam insulation boards are often used in house construction due to their advantages such as good thermal insulation performance, fast construction process, and time-saving construction. The existing microcrystalline foam insulation board is often bonded with white cement at the junction of the boards, which has many defects such as low bonding strength, poor bonding strength of the boards, general facade effect, and color difference with the boards, making its application restricted. limit. In addition, in the industry, during the processing of building materials, a large amount of marble, granite and other stone fragments are often produced. If such fragments are directly discarded, a large amount of resources will be wasted. Contents o...
