High-strength high-temperature-resistant plastic product and preparation method thereof

Abstract

The invention discloses a high-strength high-temperature-resistant plastic product and a preparation method thereof, and belongs to the technical field of plastic products. According to the high-strength high-temperature-resistant plastic product and the preparation method thereof, various materials are successively mixed according to a certain ratio, and the obtained mixed solution is granulatedby an extruder and hot-pressed to obtain the plastic product. Mica powder and short glass fibers can be added in the preparation process of the plastic product to improve the thermal deformation temperature of the plastic product and make the plastic product not easy to soften when bearing higher temperature. Meanwhile, because of the addition of inorganic granules, the flame retardance, the heatresistance and the shrinkage resistance of the plastic product are improved, and the range of application of the plastic product can be expanded. In addition, in the process in which the mixed material is cooled to the room temperature after being heated, cooling grinding balls are added into the mixed material to reduce the heat of the mixed material, so that the time required for cooling the mixed material to the room temperature is shortened, and the preparation period of the plastic product is shortened.

Description

technical field [0001] The invention relates to the technical field of plastic products, in particular to a high-strength high-temperature-resistant plastic product and a preparation method thereof. Background technique [0002] Most plastics are discarded after one-time consumption. So far, the academic circles believe that plastic products may not be decomposed in the natural environment for tens to hundreds of years due to their stable physical and chemical structures. Every year, 40 million tons of waste plastics are accumulated in the environment around the world, and about 2 million tons of waste plastics are thrown into the environment in China every year. Taking agricultural film for farmland as an example, the annual output of agricultural film in my country has reached one million tons and is increasing at a rate of 10% per year. No matter what kind of crops are covered, all film-covered soils have residual film. According to statistics, the annual residual amount...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide a kind of high-intensity high-temperature-resistant plastic product and its preparation method, which can increase the plastic The thermal deformation temperature of the product makes it difficult for plastic products to soften when they are subjected to higher temperatures. At the same time, the addition of inorganic pellets improves the flame retardancy, heat resistance and shrinkage resistance of plastic products, which is conducive to the expansion of plastic products. In addition, when the mixed material is heated and cooled to room temperature, cooling grinding balls are added to the mixed material to reduce the heat of the mixed material, thereby reducing the time required for the mixed material to cool to room temperature and shortening the life of the plastic product.
