Binder for installation of thermal insulation decorative plate

Abstract

The invention provides a binder for installation of a thermal insulation decorative plate. The binder comprises, by weight, 25 to 40% of cement, 25 to 45% of silica sand of 20 to 40 meshes, 8 to 15% of silica sand of 40 to 70 meshes, 3 to 8% of silica sand of 70 to 140 meshes, 0 to 5% of talcum powder, 0 to 5% of ground calcium carbonate powder, 2 to 8% of dispersible latex powder, 0 to 1% of cellulose ether, 0 to 0.6% of plant fibers and 0 to 0.5% of a thixotropic agent. The binder for installation of the thermal insulation decorative plate has the characteristics of high adhesion, strong anti-sliding capability, strong initial adhesion, long construction operation time and difficult skinning, effectively solves the problems produced in thermal insulation decorative plate pasting installation, guarantees enough adhesion between a thermal insulation decorative plate and a wall surface, and improves safety of the thermal insulation decorative plate in engineering application.

Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive for installing a thermal insulation decorative board. Background technique [0002] Insulation and decoration composite board is a new type of exterior wall insulation and decoration material that has emerged in recent years. It has been gradually recognized and used by users due to its excellent thermal insulation effect and decorative effect. [0003] The thermal insulation and decorative composite board is generally fixed on the building wall by the installation method of adhesive bonding + anchoring, in which the bonding of the adhesive plays a major role, and the anchoring of the anchor plays an auxiliary role. The bonding force provided by the general adhesive is more than 30 times the anchoring force provided by the anchor. [0004] There are many types of thermal insulation and decorative composite boards, and different types determine the different bonding base surfaces. The g...
