Heat-conducting toughened flame-retardant reinforced PS plastic and preparation method thereof

Abstract

The invention discloses a heat-conducting toughened flame-retardant reinforced PS plastic and a preparation method thereof, relates to the technical field of PS plastics, and aims to solve the problems that the existing PS plastic cannot meet other application requirements and the practicability is reduced due to high brittleness and poorer heat-conducting effect. The heat-conducting toughened flame-retardant reinforced PS plastic comprises the following components in parts by mass: 25-70 parts of PS resin, 5-0 parts of nanoscale silicon carbide powder, 5-20 parts of aluminum oxide, 1-8 parts of aluminum nitride, 1-15 parts of an SBS toughening agent, 5-25 parts of composite fibers, 8-15 parts of a flame retardant, 1-8 parts of a compatilizer, 0.1-1 part of a lubricant, and 0.1-0.5 part of an antioxidant. The heat-conducting toughened flame-retardant reinforced PS plastic specifically comprises the following components: 45-60 parts of PS resin, 10-15 parts of nanoscale silicon carbide powder, 7-10 parts of aluminum oxide, 4-6 parts of aluminum nitride, 5-10 parts of an SBS toughening agent, 10-20 parts of composite fibers, 8-10 parts of a flame retardant, 5-7 parts of a compatilizer, 0.3 to 0.7 part of a lubricant, and 0.1-0.3 part of an antioxidant.

Description

technical field [0001] The invention relates to the technical field of PS plastics, in particular to a thermally conductive, toughened and flame-retardant reinforced PS plastic and a preparation method thereof. Background technique [0002] PS plastic (polystyrene plastic) refers to a class of plastics that include styrene groups in their macromolecular chains. PS plastic has very good mechanical properties (high strength, fatigue resistance, dimensional stability, creep resistance), heat aging resistance, solvent resistance, water stability and insulation properties, so it is widely used in the optical industry, Electrical components and instruments and other fields. It is one of the five general-purpose plastics. [0003] However, the existing PS plastic is relatively brittle and has poor thermal conductivity, which makes it unable to meet other application requirements and reduces practicability, so it does not meet the existing needs. For this, we propose a thermally c...
