Background
Resin sand casting is a casting method for preparing a sand mold (core) using an organic resin such as a phenol resin or a furan resin as a binder. With phenolic resin as a binder, the sand of the prepared core is called precoated sand, which loosens like dry sand. The precoated sand in the model is heated (250-300 ℃), so that resin on the sand is softened and remelted, a connecting bridge is formed at a contact part between sand grains, the sand grains are adhered together, and a shell with a certain thickness and a plastic state is formed along the template.
The resin sand can be rapidly developed because it brings the following two significant benefits to the foundry industry. The resin sand can improve the quality of the casting. First, a sand mold (core) made of resin sand has high shape and dimensional accuracy. The size precision of the cast made of the resin sand is superior to that of other sand castings. Meanwhile, the strength of the resin sand mold is high, and the resin sand mold is not easy to damage in the production process, so that the stability of high-quality production of castings is further ensured.

The vein defects at the cylinder cover of the engine cylinder body are frequent, the cleaning workload of the casting is increased, the casting is even scrapped in severe cases, and the development of resin sand casting is limited.
Firstly, the anti-vein wear-resistant high-temperature-resistant film material reported in domestic literature has few formulas, the raw materials still use conventional refractory aggregate such as zircon powder, corundum powder, bauxite and the like, and the fact that the refractory powder selected by the anti-vein wear-resistant high-temperature-resistant film material should enable the wear-resistant high-temperature-resistant film material to have high permeability to a core sand sample and moderate sintering property of a coating is not considered. Secondly, the vein-proof wear-resistant high-temperature-resistant film material is still provided by foreign companies, and the blank of domestic market is different from the traditional sand casting wear-resistant high-temperature-resistant film material in consideration of the particularity of the vein-proof wear-resistant high-temperature-resistant film material. For this reason, it is a common desire of suppliers and users to develop a new type of high temperature and abrasion resistant film material.

The carrier liquid is basically used for carrying the powdery refractory material and the binder, suspending agent and the like thereof, and after the carrying work is finished, the carrier liquid loses the function and needs to be removed.

4) and discharging and bagging the prepared powdery or granular material to obtain the alcohol-based anti-vein high-temperature-resistant wear-resistant film material.

4) and discharging and bagging the prepared powdery or granular material to obtain the alcohol-based anti-vein high-temperature-resistant wear-resistant film material.
2. The preparation method of the alcohol-based vein-preventing high-temperature-resistant wear-resistant film material as claimed in claim 1, which is characterized in that: the composite refractory powder is composed of 60-80% of composite aluminum-silicon refractory powder, 8-15% of iron oxide composite mineral powder and 10-20% of high-carbon scalene ink powder in percentage by mass.
3. The preparation method of the alcohol-based vein-preventing high-temperature-resistant wear-resistant film material as claimed in claim 2, which is characterized in that: the composite aluminum-silicon refractory powder is a composite aluminum-silicon refractory powder containing bauxite, mullite, kyanite and pyrophyllite minerals; the iron oxide composite mineral powder has the effects of preventing veining and sintering and contains hematite, magnetite and gas ash concentrate.
4. The preparation method of the alcohol-based vein-preventing high-temperature-resistant wear-resistant film material as claimed in claim 1, which is characterized in that: the suspending agent is an organic modified magnesium aluminum silicate suspending agent which has strong structure forming capability and good suspension property when ethanol is used as a carrier liquid.
5. The preparation method of the alcohol-based vein-preventing high-temperature-resistant wear-resistant film material as claimed in claim 1, which is characterized in that: the binder is a composite binder consisting of phenolic resin and polyvinyl butyral which can be dissolved in ethanol.
6. The preparation method of the alcohol-based vein-preventing high-temperature-resistant wear-resistant film material as claimed in claim 1, which is characterized in that: the penetrating agent is anionic alkyl sulfonate surfactant and nonionic polyoxyethylene ether surfactant.
7. The preparation method of the alcohol-based vein-preventing high-temperature-resistant wear-resistant film material as claimed in claim 1, which is characterized in that: and the rolling time in the step 3 is 35-45 min.
