Abstract

The invention relates to latex paint finishing coat and a preparation method thereof, and in particular relates to a thinning-free one-time brush-molded latex paint finishing coat and a preparation method thereof, belonging to the field of coatings for architectural decoration. The latex paint finishing coat is prepared from the following raw materials in parts by weight: 20-29 parts of water, 1-2 parts of a glycol anti-freezing agent, 0.1-0.2 part of cellulose, 0.05-0.2 part of bentonite, 0.7-1 part of a dispersing agent, 0.1-0.2 part of a wetting agent, 0.2-0.6 part of a mineral oil anti-foaming agent, 0.1-0.2 part of an alkaline pH regulator, 15-22 parts of titanium dioxide, 8-10 parts of calcined kaolin, 0-5 parts of flash-burned kaolin, 15-25 parts of pigment/filler, 0.2-0.5 part of mildew preventive, 15-20 parts of emulsion, 1-2 parts of a coalescing agent, 0.1-0.5 part of antiseptic, 0.1-0.3 part of a thickening agent 1 and 1-2 parts of a thickening agent 2.

Description

technical field [0001] The invention relates to a latex paint finish paint and a preparation method thereof, in particular to a dilution-free one-time painting latex paint finish paint and a preparation method thereof, which belong to the field of paints for architectural decoration. Background technique [0002] Emulsion paint is currently the most widely used paint in the field of architectural decoration. Its ex-factory viscosity is usually 90-120KU. If the product ex-factory viscosity is low, the sedimentation of pigments and fillers is prone to occur. Paint manufacturers control the viscosity of latex paint to a higher level. On the one hand, it is For the consideration of product storage stability, the sedimentation of pigments and fillers can be prevented; on the other hand, logistics costs can be relatively saved. Before the construction of latex paint, it is diluted with water in a certain proportion and then painted. The painting process usually adopts the process ...
