Embodiment 1

[0016] Add 50 parts of HG-43 epoxy-modified silicone resin, 30 parts of titanium dioxide, 0.5 parts of dispersant BYK-110, and 0.3 parts of defoamer BYK052 produced by Sichuan Chenguang Chemical Co. The particle size is less than 20 μm, adding 33 parts of DBE to adjust the solid content to more than 30% to obtain the white metal thermal spray marking paint of the present invention.

Embodiment 2

[0018] Add 55 parts of HG-43 epoxy-modified silicone resin, 35 parts of titanium dioxide, 0.7 parts of dispersant BYK-110, and 0.3 parts of defoamer BYK052 produced by Sichuan Chenguang Chemical Co. The particle size is less than 20 μm, adding 35 parts of DBE to adjust the solid content to more than 30% to obtain the white metal thermal spray marking paint of the present invention.

Embodiment 3

[0020] Add 60 parts of HG-43 epoxy-modified silicone resin, 40 parts of titanium dioxide, 0.8 parts of dispersant AFCONA4010, and 0.4 parts of defoamer AFCONA2022 produced by Sichuan Chenguang Chemical Co. 20 μm or less, add 40 parts of high-boiling point organic diluent DBE to adjust the solid content to more than 30% to obtain the white metal thermal spray marking paint of the present invention.

Abstract

The invention discloses a white metal hot spraying mark coating and a production method thereof. The invention aims to provide a mark coating adapting to metal hot spraying which can be widely used in coil steel production enterprises and ensure that a cured paint film formed by the coating meets the performance requirements of good heat resistance, friction resistance, excellent attachment and obvious marks. The coating is prepared from the following components in portion by weight: 50 to 60 portions of epoxy modified organic silicon resin, 30 to 40 portions of titanium pigment, 0.5 to 1 portion of dispersant, 0.2 to 0.4 portion of defoaming agent, and 30 to 40 portions of high boiling point organic diluent. The solid content of the coating is over 30 percent. Due to the reasonable proportioning of the components, it is possible, by using the coating, to spray the marks on coil steel materials at a temperature of 400 DEG C and ensure that the cured paint film formed by the coating meets the requirements of good heat resistance, excellent attachment, water resistance and gasoline wiping resistance. The dilutent with high boiling point is adopted, so the coating has no hazard of catching fire and can meet the requirement of safe production.

Description

technical field [0001] The invention relates to a paint, more specifically, to a white metal thermal spray marking paint and a production method thereof. Background technique [0002] In recent years, coiled steel products have developed rapidly. Marking is required during the production of coiled steel. The finished product of coil steel is generally at a high temperature of about 400°C. If ordinary paint is used, it will be quickly destroyed once it is sprayed because it is not resistant to high temperature. Moreover, organic solvents in general coatings have a low boiling point, which can cause a lot of dangers when used, ranging from burns and poisoning to operators, to fires and explosions in production factories, causing serious consequences to society. Therefore, the marking paint for 400°C high-temperature coil steel has high requirements. First, there should be no fire hazard, and secondly, the marking paint should be firmly attached to the hot coil steel. At pre...
