Problems solved by technology

[0002] The traditional melamine molding compound is made of melamine-formaldehyde resin as the base material, wood pulp cellulose as the filler, and the powder molding compound is made by adding curing agent, lubricant and pigment. It is molded and pressed, and the product has a surface It is flat, non-toxic, tasteless, and drop-resistant, and is widely used in tableware, daily necessities, electrical appliances, etc.; but its specific gravity is small, without the heavy feeling of porcelain, and the temperature resistance is generally around 150 ° C, which limits the use of melamine.

Abstract

The invention relates to a high-temperature resistant porcelain imitation material and a production method thereof. The high-temperature resistant porcelain imitation material comprises the followingcomponents in percentage by weight: 30-35% of melamine formaldehyde resin, 0-10% of glass fiber, 55-65% of filler, 0-2% of coloring agent, 0.5-2% of curing agent and 0.5-3% of auxiliary agent. The production method of the high-temperature resistant porcelain imitation material comprises the steps of resin synthesizing, raw material mixing, wet material drying and dried material grinding and sieving. The porcelain imitation material which has vivid porcelain sensation and can resist the temperature of more than 220 DEG C is obtained by adjusting the formula of the molding material. The porcelain imitation material can be widely used for the industries of tableware, articles for daily use and the like, is especially suitable for products with higher high-temperature resistant requirements, such as electrothermal cookers and the like, makes up the defect of low temperature resistance of the original melamine molding material, and expands the application field of the melamine molding material.

Description

technical field [0001] The invention relates to a high-temperature-resistant porcelain-like material and a production method thereof, in particular to a high-temperature-resistant porcelain-like material of amino molding compound.
