Embodiment 1

[0024] For the formulation of lost foam cast steel paint, the ingredients required to prepare 100kg lost foam cast steel paint are as follows:

[0025] Bauxite 55.8kg, zircon sand powder 40kg, phenolic resin 1.5kg, white latex 3kg, silica sol 3kg, lithium bentonite 3kg, isopropanol 0.1kg, CMC: 1.5kg, JFC: 0.1%kg.

[0026] The process method of the above-mentioned lost foam cast steel coating formula is completed according to the following steps:

[0027] 1. According to the proportion of paint powder and water ratio of 1:0.7, put it into the blender, measure the Baume degree after fully stirring, and control the Baume degree at 65 by diluting with water;

[0028] 2. According to production requirements, it can be dip-coated twice or three times;

[0029] 3. The thickness of the coating is 1-2mm.

[0030] The stirring time of the present embodiment is controlled at 1-1.5 hours.

Embodiment 2

[0032] The difference between this embodiment and embodiment one is: the required ingredients for preparing 100kg lost foam cast steel paint are as follows:

Abstract

The invention discloses a paint formula, particularly discloses a lost foam steel-casting paint formula and a technology method thereof. The lost foam steel-casting paint formula comprises the following components: 40-60% of bauxite, 30-50% of zirconium sand powder, 1-3% of phenolic resin, 1-5% of white emulsion, 1-5% of silica sol, 1-5% of lithium bentonite, 0.1-0.5% of isopropanol, 0.5-2% of CMC and 0.1-0.5% of JFC. The technology method of the lost foam steel-casting paint formula comprises the following steps: 1, in the ratio of paint powder to water of 1:0.7, putting the paint powder and the water into a stirrer for stirring for 1-1.5 hours, then measuring baume degree, and controlling the baume degree between 65 and 70 through dilution with water; 2, according to production requirements, dip-coating for two times or three times; and 3, the thickness of a coating layer being 1-2 mm. White molds of the paint formula have good wettability, good coating and hanging properties, high strength and good air permeability.

Description

technical field [0001] The invention relates to a paint formulation, in particular to a paint formulation for lost foam cast steel and a process method thereof. Background technique [0002] In the prior art, the paint for lost foam cast steel has poor wettability with the white mold, poor coating hangability and low strength. The paint has poor air permeability. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a formulation and a process method of the lost foam cast steel coating with good white mold wettability, good coating and hangability, high strength and good air permeability. [0004] Lost foam cast steel paint formula of the present invention, this lost foam cast steel paint formula composition is as follows: [0005] Bauxite 40-60%, zircon sand powder 30-50%, phenolic resin 1-3%, white latex 1-5%, silica sol 1-5%, lithium bentonite 1-5%, isopropanol 0.1-0.5 %, CMC: 0.5-2%, JFC: 0.1-0.5%.
