Abstract

The invention discloses a preparation method for a heat insulation wall paint. The preparation method comprises the following steps of preparing a modified crylic acid microemulsion; mixing TiO2, shale micro powder and ZnO to obtain a mixture and then adding the mixture into 20-25wt% of water and mixing and ball-milling at room temperature; preparing an assistant mixed liquor, and mixing uniformly at room temperature; and putting the prepared mixed filler into a reaction kettle, and stirring rapidly so as to obtain the needed paint. The heat insulation wall paint has a strong adhesive force to matrixes such as walls, metals, wooden products and the like, can achieve the heat insulation purpose by coating the paint on the surface of matrixes by about 0.3-0.5mm, and is an ideal environment-friendly paint.

Description

technical field [0001] The invention belongs to the technical field of wall paint production, in particular to a method for making heat-insulating wall paint. Background technique [0002] At present, the commonly used thermal insulation technology in China is the external thermal insulation technology of the external wall. The external thermal insulation technology of the external wall is to fix a layer of thermal insulation material on the outside of the main wall structure under the action of the bonding material, and to install it on the outside of the thermal insulation material. Reinforced with fiberglass mesh and painted with bonding mastic. At present, there are mainly several external thermal insulation methods such as polystyrene board thin plaster external wall thermal insulation, polystyrene board cast-in-place concrete external wall thermal insulation, polyphenylene particle slurry external wall thermal insulation, etc. [0003] Exterior wall thermal insulation...
