Problems solved by technology

Although the country formulated the relevant industry standards of "Primers for Building Interior and Exterior Walls" (JG / T 210-2007) as early as 2007 to regulate the technical requirements of related products, even products that meet the requirements of this standard still have a large number of defective problems. Existence, mainly manifested in the poor permeability of the product, weak adhesion to the putty, and failure to adhere to the putty layer; the drying time of the primer product is too short or too long, resulting in that when the masking paper used to protect the grid seams is uncovered, the masking paper cannot Partial or complete peeling off of the paint film when uncovered or uncovered, resulting in a large amount of rework required for construction

Abstract

The invention relates to water-based high-adhesion diving joint priming paint, as well as a preparation method and application thereof. The priming paint comprises the following components in percentage by mass: 38.0-43.2% of epoxy-modified sealing emulsion, 0.26-0.3% of hydroxyethyl cellulose, 0.13-0.20% of AMP-95, 8.0-9.0% of an inorganic pigment, 18.7-27.2% of a filler, 0.13-0.20% of a wetting dispersant, 0.1-0.3% of a polyether-modified flatting agent, 0.2-0.4% of an antifoaming agent, 0.1-0.22% of a bactericide, 0.15-0.80% of a thickening agent, 1.5-3.4% of a coalescing agent, 1.5-8.0% of an anti-freezing agent and 15.69-27.28% of water, wherein the pH value of the water-based high-adhesion diving joint priming paint is 8.0-9.5. The water-based high-adhesion diving joint priming paint disclosed by the invention is low in content of VOC (volatile organic compounds), does not contain any substance causing harm to the human body and the environment and has excellent permeability; the priming paint product can be effectively adhered by textured paper, and when the priming paint does not need to be protected after construction completion, the textured paper can be smoothly removed. The water resistance, alkali resistance, alkali burnout resistance and salting-out resistance of the water-based high-adhesion diving joint priming paint products disclosed by the invention can meet standard technical requirements in the industry of priming paint for building external walls.

Description

technical field [0001] The invention relates to the field of decorative materials, in particular to exterior wall decorative coatings, in particular to a water-based high-adhesion grout primer and its preparation method and application. Background technique [0002] With the continuous development of the real estate market, new architectural coatings have also been applied in batches in the decoration materials of construction projects. The quality of the matching primer products is uneven, which brings great difficulty to the selection of the tenderer and the construction party. In the application of large-area exterior wall paint construction, the grid is divided by means of dividing seams, on the one hand, it is convenient for construction, and on the other hand, it improves the effect of large-area decoration. Therefore, it is particularly important to deal with the on-site grid joints. Although the country formulated the relevant industry standards of "Primers for Bui...
