Abstract

The invention discloses an unsaturated polyester material electrostatically sprayed at the high temperature of 38 DEG C and gelatinized for 80 minutes. The material comprises, by weight, 38-48 parts of unsaturated polyester resin, 1-3 parts of polishing aids, 35-55 parts of inorganic fillers, 3-6 parts of solvents, 1-2 parts of anti-settling agents, 1-2 parts of enhanced anti-settling rheologicalagents, 1-3 parts of hardening agents, 0.1-0.5 part of defoaming agent, 0.2-0.5 part of leveling agent, 0.1-0.2 part of conducting assistants, 0.5-0.7 part of polymerization inhibitor, 3-5 parts of adhesion promoters and 0.5-0.7 part of slow-drying anti-greening dispersing agent. The unsaturated polyester material has the advantages that the material is suitable for rotary-cup-type electrostatic spraying, and the paint utilization rate is increased; the gelatinization time reaches 80 minutes in an environment with the temperature of 38 DEG C, and performance and environmental protection requirements are met at the same time.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an unsaturated polyester material which is electrostatically sprayed at a high temperature of 38°C and has a gelation time of 80 minutes. Background technique [0002] With the continuous advancement of science and technology, people pay more and more attention to environmental protection. The traditional manual spraying operation is gradually replaced by mechanical spraying, and electrostatic spraying has gradually become the mainstream. Because the rotating cup electrostatic spraying adopts cyclic operation to improve the utilization rate of paint, it has a high requirement for the gelation time of unsaturated polyester materials, which needs to reach 80 minutes at 38 ° C. The gelation time of ordinary unsaturated polyester materials Only about 30 minutes. [0003] Therefore, there is an urgent need in this field for a construction tolerance that can broaden the unsaturated...
