Abstract

The invention provides high-hardness modified plastic. The high-hardness modified plastic comprises the following substances in percentage by mass: 60%-80% of PC, 5%-15% of ABS, 10%-30% of PPS, 0.1%-2% of a flame-retardant agent and 0.2%-1% of a toughening agent. The invention also provides a preparation method of the high-hardness modified plastic. The preparation method comprises the following steps: firstly, weighing all substance materials according to mass percentage, baking the weighed materials in a baking oven with the temperature set to be 200 DEG C for 2 hours, then carrying out high-speed stirring on the baked materials in a stirring machine at the temperature of 300 DEG C, injecting the stirred materials into a mold under high pressure, and performing molding, cooling and drying, thereby preparing the high-hardness modified plastic. The high-hardness modified plastic provided by the invention integrates the comprehensive performances such as pressure resistance, smash resistance, drilling resistance, fire resistance and the like simultaneously, and is simple in production process, convenient in processing and lower in cost.

Description

technical field [0001] The invention relates to a modified plastic, in particular to a high-hardness modified plastic. Background technique [0002] Modified plastics are widely used in daily life. Through the processing of ordinary plastics in a certain way, the performance of plastics is enhanced, which makes up for the deficiencies of ordinary plastics in terms of hardness, abrasion, corrosion, and heat resistance. The manufacturing cost of the product is reduced. [0003] Some modified plastics in the prior art are not enough to take into account the comprehensive properties of compressive resistance, smashing resistance, drilling resistance, fire prevention, etc. at the same time. Contents of the invention [0004] (1) Technical problems to be solved [0005] The technical problem to be solved by the present invention is to provide a high-hardness modified plastic with good comprehensive properties such as compression resistance, smash resistance, drilling resistanc...
