Easy-to-cure wear-resisting raw lacquer coating for concentrating table and preparation method of easy-to-cure wear-resisting raw lacquer coating

Abstract

The invention discloses an easy-to-cure wear-resisting raw lacquer coating for a concentrating table and a preparation method of the easy-to-cure wear-resisting raw lacquer coating. The wear-resisting raw lacquer coating is prepared from, by mass, 60%-75% of raw lacquer, 10%-18% of nanocrystal cellulose, 8%-15% of modifying agent, 1%-7% of dispersing agent, 5%-8% of diluents, 2%-5% of functional assistant and 0.5%-1.5% of coupling agent. By means of reasonable compounding of nanocrystal cellulose, the raw lacquer and other assistants, the defects that the requirement of the raw lacquer for the construction condition is high, and a specific temperature and humidity environment is needed are overcome, so that the raw lacquer coating is not influenced by temperature or humidity, and can be cured under the conditions of low temperature and low humidity, normal-temperature construction is achieved, the construction period of the raw lacquer can be shortened, and production cost can be reduced. The advantages that the raw lacquer is good in wear resistance and moderate in friction force are kept. It is proved through experiments that the wear-resisting raw lacquer coating has excellent corrosion resisting capacity and is good in acid resistance, water resistance and medium resistance.

Description

technical field [0001] The invention belongs to the technical field of wear-resistant coatings. More specifically, it relates to an easy-curable wear-resistant raw lacquer coating for mineral dressing shakers and a preparation method thereof. Background technique [0002] The beneficiation shaking table is used as a gravity separation equipment, which has been widely used in the separation of placer gold and other minerals, mainly for gold or coal preparation. The beneficiation shaking table can make the ore particles move in different directions according to their density and particle size, and fan out from the ore feeder along the diagonal, and then discharge along the edge of the bed in sequence. The ore discharge line is very long, which can accurately produce A variety of products with different qualities are produced, such as concentrate, sub-concentrate, medium concentrate and tailings. The surface performance of the shaker, especially the wear resistance, is one of...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defects and deficiencies of existing raw lacquers that are greatly affected by temperature and humidity, dry slowly under low temperature and low humidity conditions, and need to be constructed under constant temperature and humidity conditions, and provide a kind of lacquer that is not affected by temperature and humidity. The wear-resistant raw lacquer coating applied under low temperature and low humidity conditions overcomes the defects that raw lacquer construction conditions are high and requires a specific temperature and humidity environment. It can be dried and solidified at room temperature, which can shorten the construction period of raw lacquer and reduce production costs. The advantages of raw lacquer wear resistance and moderate friction
