Embodiment 1

[0022] Formulation of the real casting paint, prepare 100kg of the real casting paint composition as follows:

[0023] Bauxite 40kg, quartz powder 44kg, flake graphite 10kg, lithium bentonite 1.5kg, phenolic resin 1kg, polyvinyl butyral 3.5kg.

[0024] The process method of solid casting paint, according to the different products to be painted, is diluted with industrial alcohol to the required viscosity, density or Baume degree, and it should be fully stirred before use, and the casting should be painted once or twice. It is ethanol or methanol with content ≥98%.

Embodiment 2

[0026] The difference between the present embodiment and embodiment one is that the composition of this solid casting coating of 100kg is prepared as follows:

[0027] Bauxite 35kg, quartz powder 45kg, flake graphite 14kg, lithium bentonite 1.5kg, phenolic resin 1kg, polyvinyl butyral 3.5kg.

Embodiment 3

[0029] The difference between the present embodiment and embodiment one is that the composition of this solid casting coating of 100kg is prepared as follows:

[0030] 30 kg of bauxite, 50 kg of quartz powder, 15 kg of flake graphite, 1 kg of lithium-based bentonite, 1 kg of phenolic resin, and 3 kg of polyvinyl butyral.

Abstract

The invention discloses a coating formula and particularly discloses a formula and technique of a full-mould casting coating. The formula of the full-mould casting coating contains 30-40% of bauxite, 40-50% of quartz powder, 10-20% of flake graphite, 1-3% of lithium-based bentonite, 0.5-1.5% of phenolic resin and 2-4.5% of polyvinyl butyral. The technique of the full-mould casting coating comprises the following steps of: according to different products to be painted, diluting the full-mould casting coating to the required viscosity, density or baume degree by adopting industrial alcohol, and fully and uniformly stirring before the full-mould casting coating is used, and painting a casting once or twice. The full-mould casting coating is better in suspension stability, low in gas evolution and high in crack resistance.

Description

technical field [0001] The invention relates to a paint formulation, in particular to a full mold casting paint formulation and a process method thereof. Background technique [0002] In the prior art, the suspension stability of the solid casting coating is poor, the gas generation is high, and the crack resistance is poor, resulting in poor thixotropy and leveling, which affects the adhesion performance on the white mold, and the anti-sand sticking performance is poor after use. Not easy to clean up. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a solid casting coating formulation and a process method thereof with good suspension stability, low gas generation and high crack resistance. [0004] Full mold casting paint formula of the present invention, this full mold casting paint composition is as follows: [0005] Bauxite 30-40%, quartz powder 40-50%, flake graphite 10-20%, lithium-based bentonite 1-3...
