High-flame-retardant, high-strength and high-temperature-resistant easy-to-form thermoplastic plate and preparation method thereof

Abstract

The invention discloses a high-flame-retardant, high-strength and high-temperature-resistant easy-to-form thermoplastic plate and a preparation method thereof, and belongs to the field of easily-formed thermoplastic plates. The thermoplastic plate is prepared from the following raw materials by weight: 10-30 parts of MBS, 10-30 parts of polyvinyl chloride resin, 30-45 parts of ABS, 8-15 parts of PMMA, 1-2 parts of a heat stabilizer, 0.5-2 parts of an auxiliary stabilizer, 1-2 parts of an o-hydroxybenzophenone derivative, 1-4 parts of an outer lubricant, 1-4 parts of an inner lubricant, 1-2 parts of a processing aid, 2-5 parts of an impact modifier and 0-1 part of a pigment. When the temperature increases to 80 DEG C, the processing aid, the pigment and the impact modifier are added in parts by weight; when the temperature increases to 125 DEG C, the mixture is fed into a cold mixing device to be cooled and stirred, the stirring speed being 80 rpm; and the product is obtained when the temperature decreases to 40 DEG C. The product is reasonable in components and simple to prepare, has remarkable advantages and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of easy-to-form thermoplastic sheets, in particular to an easy-to-form thermoplastic sheet with high flame retardancy, high strength and high temperature resistance and a preparation method thereof. Background technique [0002] At present, there are dozens of varieties of plates for new high-speed rail and aviation, which are generally plastic plates made of glass fiber reinforced plastics and ordinary polymer materials. Conventional thermoplastic sheets have low fire rating and temperature resistance, and low compressive strength. There are certain safety hazards in use, so it is necessary to improve the performance of conventional thermoplastic sheets to effectively improve the strength and environmental safety of the sheets; [0003] The lightweight plate industry has become one of the key research and development topics for the current development of low-carbon economy. All thermoplastics and glass fi...

Problems solved by technology

The thermoplastic composite materials in the prior art, because the reinforcing material contained in it is glass fiber, the longitudinal and transverse tensile strength, bending strength, impact strength and flexural modulus of the finished product still cannot meet the needs of users.
