Embodiment 1

[0014] An amino molding compound material powder for processing melamine tableware, which is made of the following raw materials in weight percentage: 15% sodium citrate, 2% titanium dioxide, 48% amino molding compound particles, 20% wood fiber, hard Zinc fatty acid 15%.

[0015] The preparation method is:

[0016] (1) Ingredients: First, add zinc stearate and sodium citrate into the batching tank with water, and the materials in the batching tank are heated to 85°C by steam to fully mix the materials in the tank, and then the mixed liquid is combined with amino Molding compound particles and titanium dioxide are added to the kneader in a certain proportion;

[0017] (2) Kneading of materials: The prepared materials are fully mixed and stirred through the mutual cooperation and reverse rotation of the paddles in the kneader, and at the same time, the interlayer of the kneader is used to input steam to heat the materials with steam, so that the moisture in the materials is qui...

Embodiment 2

[0021] An amino molding compound material powder for processing melamine tableware, which is made of the following raw materials in weight percentage: 16% sodium citrate, 2% titanium dioxide, 50% amino molding compound particles, 18% wood fiber, hard Zinc fatty acid 14%.

[0022] The preparation method is:

[0023] (1) Ingredients: First, add zinc stearate and sodium citrate into the batching tank with water, and the materials in the batching tank are heated to 85°C by steam to fully mix the materials in the tank, and then the mixed liquid is combined with amino Molding compound particles and titanium dioxide are added to the kneader in a certain proportion;

[0024] (2) Material kneading: through the paddles that cooperate with each other and rotate forward and reverse in the kneader, the prepared materials are fully mixed and stirred, and at the same time, the interlayer of the kneader is used to input steam to heat the materials to make the moisture in the materials quickl...

Abstract

The invention belongs to the field of melamine products, and in particular relates to an amino molding compound powder for processing melamine tableware and a preparation method thereof, which is made of the following raw materials in weight percentage: sodium citrate 15%-25%; titanium White powder 2%‑4%; amino molding compound granules 45%‑55%; wood fiber 18%‑28%; zinc stearate 15%‑25%. The preparation method is batching, material kneading, material drying and crushing and ball milling. During the material kneading process, the prepared materials are fully mixed and stirred by the paddles that cooperate with each other and rotate forward and backward in the kneader, and at the same time, use the steam of the kneader to heat The device heats the material with steam, so that the moisture in the material can be quickly and fully volatilized. The material ratio of the invention is scientific and reasonable, and the melamine product produced has good quality and tightness, superior scratch resistance, simple and fast operation, complete water volatilization during the kneading process, shortens production time, improves work efficiency, and enhances product quality.

Description

technical field [0001] The invention belongs to the field of melamine products, and in particular relates to amino molding compound powder for processing melamine tableware and a preparation method thereof. Background technique [0002] Melamine moldings for food are a type of plastic container, usually called melamine. Melamine tableware is more and more commonly used by families, schools, restaurants, fast food restaurants, and snack bars. Especially because of its unbreakable characteristics, many families use it as children's tableware. Due to its wide range of applications and convenience and practicability , Melamine tableware is recognized by more and more people. The production of traditional melamine products has shortcomings such as poor high temperature resistance, poor weather resistance, low strength, and low production efficiency due to deficiencies in ingredients and kneading of materials. Contents of the invention [0003] The technical problem to be solv...
