Problems solved by technology

However, in practical applications, the dispersion state of the micronized inorganic powder particles in the polymer is not ideal.
Due to the small particle size, large specific surface area, and high surface energy of the micronized powder, it is easy to agglomerate into aggregates, resulting in difficult processing of polymers and performance degradation

Abstract

The invention discloses inorganic powder plastic, which consists of superfine inorganic powder particle microcapsules wrapped by coatings and a macromolecular polymer. The inorganic powder plastic comprises the following components in part by weight: 75 to 85 parts of inorganic powder microcapsules, and 15 to 25 parts of macromolecular polymer. Wherein, the inorganic powder microcapsules consist of inorganic powder with the particle diameter of 2.5 to 5.0 microns and coatings consisting of an active agent, an initiator, an interface modifier and a dispersant; and the macromolecular polymer isat least one of polystyrene, polyethylene glycol terephthalate, lowed density polyethylene, high density polyethylene, metallocene polyethylene, linear low density polyethylene, acrylonitrile-butadiene-styrene copolymer, polypropylene and the like. The inorganic powder plastic (commonly called as stone plastic) has good flowability and thermal plastic processing property, greatly lowers the cost of a plastic product, and reduces the dependency of the plastic product on petroleum resources.

Description

Technical field [0001] The present invention involves an inorganic powder plastic (commonly known as stone plastic) and its preparation methods. Background technique [0002] Apply the inorganic powder to the production of plastic products for a long time.It can not only reduce costs, but also improve the performance of plastic products.At present, in the production of plastic products, inorganic powder is mainly compatible with resin compatibility with the surface of the powder on the surface of the powder. The amount of inorganic powder is generally only 10%-30%.With the gradual reduction of petroleum resources, the price of plastic raw materials continues to rise, and people want to use more low -cost inorganic powder to replace plastic.However, if the filling of the inorganic powder in plastic products is further improved, it will seriously affect the mechanical properties of the product.Therefore, it is essential to improve the further promotion and application of inorganic ...
