Problems solved by technology

[0003] When the general waterproof emulsion is used, its own thermal insulation and sound absorption effect may be poor. When it is applied on the board or filled between the boards, it may not be able to improve the thermal insulation effect of the gap between the boards, and the heat loss in the gap may be relatively large.

Abstract

The invention discloses a method for preparing a waterproof emulsion of a thermosetting composite polystyrene foam insulation board. The method comprises: weighing raw materials according to a weightratio, mixing the raw materials, adding the weighed acrylic emulsion, polyvinyl alcohol, a resin coated adhesive PBA, ethyl acetate, an ethylene-vinyl acetate copolymer and light calcium powder into areactor, carrying out mixing, grinding expanded perlite and calcium silicate, adding the expanded perlite and calcium silicate powder into the mixture, and discharging the waterproof emulsion througha reactor. In preparation of the waterproof emulsion, expanded perlite and calcium silicate are used and are uniformly mixed in the waterproof emulsion in a form of powder particles so that the heatinsulation effects of the waterproof emulsion are improved.

Description

technical field [0001] The invention relates to a method for preparing a waterproof emulsion, in particular to a method for preparing a waterproof emulsion for a thermosetting composite polystyrene foam insulation board, and belongs to the technical field of preparation and application of waterproof emulsion. Background technique [0002] Thermosetting composite polystyrene foam insulation board is a kind of insulation board, which is generally used for wall insulation and heat insulation; when installed on the wall, it may be covered with waterproof emulsion to make it stick to the wall, and the waterproof emulsion Gaps between panels can be filled. [0003] When the general waterproof emulsion is used, its own thermal insulation and sound absorption effect may be poor. When it is applied on the board or filled between the boards, it may not be able to improve the thermal insulation effect of the gap between the boards, and the heat loss in the gap may be relatively large. ...
