Preparation process of novel polymer material for coating preparation

Abstract

The invention discloses a preparation process of a novel polymer material for coating preparation. The preparation process comprises the following steps: S11, weighing the following raw materials in parts by weight: 50-70 parts of a polymer mixed base material, 3-4 parts of an antibacterial agent, 4-5 parts of graphene, 1.6-2 parts of a coupling agent, 5-6 parts of a curing agent and 1-1.2 parts of a flatting agent; s12, adding the weighed polymer mixed base material, graphene and coupling agent into stirring equipment together, stirring for the first time under the condition that the temperature is 25-40 DEG C, naturally cooling to 0-5 DEG C, then adding the flatting agent, antibacterial agent and curing agent into the stirring equipment together, and stirring for the second time, thereby obtaining the coating after the second-time stirring is completed; the high polymer material product meets the low-temperature curing condition, the water resistance, weather resistance and mechanical performance of the coating can be improved, it is guaranteed that the coating has good fluidity in the curing process, and the coating has good appearance and mechanical performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation process of a new polymer material for coatings. Background technique [0002] Coatings, traditionally known as paints. 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. It is usually based on resin or oil or emulsion, with or without adding pigments and fillers. Agents, viscous liquids prepared with organic solvents or water, whether they are traditional coating products made of natural substances or modern developments of coating products made of synthetic chemical products, are all organic chemical polymer materials. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a kind of multifunctional engineering materials, which are an important industry in the chemic...

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. It is usually based on resin or oil or emulsion, with or without adding pigments and fillers. Agents, viscous liquids prepared with organic solvents or water, whether they are traditional coating products made of natural substances or modern developments of coating products made of synthetic chemical products, are all organic chemical polymer materials. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a kind of multifunctional engineering materials, which are an important industry in the chemical industry. The base materials of existing coatings often need to add fillers. And the corresponding additives can form the paint for spraying, which requires a lot of time to prepare the finished paint before spraying, so as to ensure the excellent performance of the paint, and when the substrate of the paint is directly sprayed, the performance of the sprayed coating is insufficient To meet the needs of users, and the subsequent need to spray the finished paint
