Embodiment

[0101] According to the method described above, the performance of the polyethersulfone ultrafine powder of the present invention is tested. in:

[0102] (1) In the test of mixing degree with water, add 100g of polyethersulfone micropowder particles to 100g of purified water containing 1wt% wetting agent W22 (Huanqi Chemical (Guangdong) Co., Ltd.). The obtained mixed solution was dispersed at a low speed of 100 rpm for 20 minutes, then left to settle, and the layering was observed. The measured degree of mixing of the polyethersulfone fine powder particles with water is shown in Table 1 below.

[0103] The inventors found through research that the polyethersulfone ultrafine powder particles within the particle size range of the present invention have better affinity for water.

[0104] (2) In the drying and film-forming ability test after the paint is made, polyethersulfone micropowders with different particle sizes are made into paint according to the following formula:

Abstract

The invention relates to the field of materials and coatings. Specifically, the invention discloses polyethersulfone ultrafine powder and its use in preparing coatings, as modifiers for plastics and glass, and coatings containing the polyethersulfone ultrafine powders. The particle diameter of the polyethersulfone ultrafine powder of the present invention is greater than 0.1 μm and less than or equal to 5 μm. Compared with the polyethersulfone micropowder falling outside the particle size range of the present invention, the polyethersulfone ultrafine powder of the present invention not only maintains the advantages of high temperature resistance, high strength, corrosion resistance, etc., but also has the following advantages: easy to mix with other materials Mixing, better fluidity, higher affinity for water, not easy to form agglomerates in solvents, stable performance after dissolution, and can significantly reduce the amount of organic solvents used in the preparation of coatings, which not only reduces production costs , but also conducive to environmental protection. In addition, when the polyethersulfone ultrafine powder of the present invention is used as a modifier for plastics and glass, the surface smoothness of the resulting plastic plate and glass product is significantly improved.

Description

technical field [0001] The invention relates to the field of materials and coatings. In particular, the present invention relates to polyethersulfone materials and their use in the preparation of coatings, as modifiers for plastics and glass, and coatings containing said polyethersulfone materials. Background technique [0002] Polyethersulfone (PES) is a thermoplastic polymer material with excellent comprehensive properties developed by the British ICI company in 1972. Polyethersulfone is one of the special engineering plastics that have been widely used in recent years. It has excellent heat resistance, physical and chemical properties (such as easy coloring, high strength, corrosion resistance, wide pH range and oxidation resistance, etc.) and insulation properties. [0003] Especially because polyethersulfone has good heat resistance, steam resistance, corrosion resistance, easy coloring and non-toxicity, etc., it can be used as an adhesive agent for coatings to prepar...
