Problems solved by technology

There is a resin rice milling wheel in the prior art, which is made by mixing phenolic resin and epoxy resin with abrasives as a binder. In the process of preparing the resin rice milling wheel, the raw materials are not easy to mix and the binder is easy to mix. Agglomerates, resulting in uneven hardness of the rice grinding wheel, which is easy to fall off during use, thereby affecting the precision of the processed rice, and the service life is short; and because the abrasives such as silicon carbide used are high energy consumption, high pollution and resources Non-toxic abrasives, so the cost is high, the pollution is heavy, and the consumption of national resources

preparation example Construction

[0036] The specific implementation of the preparation method of the rice milling wheel proposed in the present invention sequentially includes the following steps:

[0037] 1) Weigh the abrasive, new phenol resin, liquid phenol resin, epoxy resin, dibutyl ester and hemihydrate gypsum powder according to the proportion. The proportion of each raw material is as follows:

[0038] 100 parts by weight of abrasive,

[0039] New phenol resin 1~50 parts by weight

[0040] 2-60 parts by weight of liquid phenolic resin,

[0041] 0.5-40 parts by weight of epoxy resin,

[0042] 1-10 parts by weight of dibutyl ester,

[0043] Hemihydrate gypsum powder 0.5 to 80 parts by weight.

[0044] 2) Mix the weighed raw materials to obtain molding materials, specifically:

[0045] Firstly, liquid phenolic resin, epoxy resin and dibutyl ester are mixed to obtain a binder mixture; then the binder mixture is mixed with abrasive; then new phenol resin is added for mixing; finally, hemihydrate gypsum powder is added...

Abstract

The invention discloses a rice milling grinding wheel and a preparation method thereof. The rice milling grinding wheel is prepared by adopting the following raw materials by proportion: 100 parts by weight of grinding materials, 1-50 parts by weight of new phenolic resin, 2-60 parts by weight of liquid phenolic resin, 0.5-40 parts by weight of epoxy resin, 1-10 parts by weight of dibutyl ester and 0.5-80 parts by weight of semi-hydrated gypsum powder. The rice milling grinding wheel is low in cost, the raw materials can be mixed evenly and easily, global hardness uniformity is excellent, and service life is long.

Description

Technical field [0001] The invention belongs to the field of food processing, and particularly relates to a rice milling wheel and a preparation method thereof. Background technique [0002] The rice milling wheel is an important part of the rice mill, which directly determines the precision of the grains milled. There is a resin rice polishing wheel in the prior art, which is made by mixing phenolic resin and epoxy resin as a bonding agent with abrasives. In the process of preparing the resin rice polishing wheel, the raw materials are not easy to mix and the bonding agent is easy. Agglomeration causes uneven hardness of the rice milling wheel, which is easy to fall off during use, which affects the accuracy of the processed rice and has a short service life; and because the abrasives such as silicon carbide used are high energy consumption, high pollution and resources Because of its high cost, heavy pollution and consumption of national resources. Summary of the invention [...
