Abstract

The invention discloses a waterproof coating for a water-based ceramic tile and a preparation method of the waterproof coating, and belongs to the technical field of coatings. The waterproof coating for the water-based ceramic tile is prepared from a component A and a component B, wherien the weight part ratio of the component A to the component B is 1: 2.5; the component A comprises the followingcomponents in parts by weight: 60-80 parts of polyether polyol, 15-30 parts of isocyanate and 1-5 parts of a plasticizer; and the component B comprises the following components in parts by weight: 30-60 parts of petroleum resin, 5-15 parts of compatilizer, 10-15 parts of plasticizer, 1-5 parts of stabilizer, 5-10 parts of water and 20-35 parts of filler. According to the invention, the preservative is added into the waterproof coating, so that the waterproof coating has good corrosion resistance, and is not easy to erode and damage by acid rain in case of acid rain; the waterproof coating canabsorb ultraviolet rays in sunlight by adding the ultraviolet light, so that the aging and discoloring rate of the ceramic tile can be reduced; and by adding a fire retardant, a better flame-retardant effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based waterproof coating for ceramic tiles and a preparation method thereof. Background technique [0002] Paint, traditionally known as paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called a coating film, also known as a pa...
