Embodiment 1

[0045] Embodiment 1: a kind of unsaturated polyester flow-coating white primer, each component and its corresponding parts by weight are shown in Table 1, and are prepared by the following steps:

[0046] Step 1, prepare unsaturated polyester resin, mix and heat corresponding parts by weight of maleic anhydride, isophthalic anhydride and propylene glycol, condense and reflux, heat up to 80°C in 15min, and rotate at 200rpm; then The temperature is raised to 160°C in 50min, the rotation speed is 400rpm, and finally the temperature is raised to 195°C in 60min, the rotation speed is 300rpm, and the reaction is maintained for 60min to obtain an unsaturated polyester resin;

[0047] Step 2, mix materials, and sequentially add corresponding parts by weight of polyoxyethylene trisiloxane, alkyl glucamide and epoxy phosphate in the unsaturated polyester resin for high-speed stirring, and the rotating speed is 5000 rpm, and the stirring time is 5000 rpm. For 20min, the mixture was obtai...

Embodiment 2-8

[0049] Example 2-8: An unsaturated polyester flow-coating white primer, the difference from Example 1 is that each component and its corresponding parts by weight are shown in Table 1.

Abstract

The invention discloses an unsaturated polyester flow coating white primer and a preparation process thereof, the primer and the process relate to the technical field of paint production, and solve the problem of easy paint stripping in the use process caused by the fact that the overall adhesion of the paint is poor due to poor stability of the paint. The primer comprises the following componentsin parts by weight: 5-9 parts of maleic anhydride; 9-15 parts of isophthalic anhydride; 10-18 parts of propylene glycol; 3-5 parts of adhesion promoters; 2-3 parts of polyoxyethylene trisiloxane; 3-6parts of alkyl glucamide; 5-8 parts of butyl acetate; 6-7 parts of xylene; 4-7 parts of dispersants; 2-3 parts of anti-settling agents. The unsaturated polyester flow coating white primer has good adhesive force and good stability, and is not easy to strip during use.

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to an unsaturated polyester flow-coating white primer and a preparation process thereof. Background technique [0002] Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, signs and other special purposes. [0003] A kind of wear-resistant wood paint and its preparation process are disclosed in the Chinese invention patent with the announcement number CN106916472A, which is composed of the following raw materials by weight: 10-15 parts of wollastonite, Mongolian 5-15 parts of exfoliating clay, 5-10 parts of kaolin, 5-10 parts of talc, 5-10 parts of rosin resin, 1-5 parts of polyurethane, 1-5 parts of acrylic resin, 5-10 parts of auxiliary agent and appropriate amount of water; The auxiliary agent is composed of the following raw materials in parts by weight: 10-15 parts of camellia oil, 5-15 parts of calcium carbonate...
