Halogen-free flame-retardant ABS alloy material and preparation method thereof

Abstract

The invention discloses a halogen-free flame-retardant ABS (Acrylonitrile Butadiene Styrene) alloy material and a preparation method thereof, and belongs to the field of high polymer materials. The halogen-free flame-retardant ABS alloy material is prepared from the following components in parts by weight: 75-90 parts of ABS resin, 13-20 parts of a DIDOPO flame retardant, 10-20 parts of a charring agent, 2-5 parts of a flame-retardant synergist, 3-6 parts of a compatilizer, 0.2-0.7 parts of an antioxidant and 0.2-0.4 parts of a lubricant. Meanwhile, the invention discloses a preparation method of the halogen-free flame-retardant ABS alloy material. The halogen-free flame-retardant ABS alloy material has the tensile strength of 43-46 MPa and the cantilever notched impact strength of 15-27 KJ / m < 2 > on the premise of meeting the UL94 V0 2.0 mm flame retardant property, and meanwhile, has good flame retardant property and mechanical property. The halogen-free flame-retardant ABS alloy material disclosed by the invention is excellent in comprehensive performance, simple in preparation process and suitable for being applied to preparation of flame-retardant materials.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a halogen-free flame-retardant ABS alloy material and a preparation method thereof. Background technique [0002] The flame retardant products commonly used in ABS on the market are widely used as bromine antimony flame retardant, the total addition amount is about 15-20%, the flame retardant is stable, and the physical properties also meet the use requirements. However, with the development of time, reducing and preventing the adverse effects of halogen flame retardants on the environment and human health has become an urgent problem to be solved in the polymer material industry. Halogen-free flame-retardant polymers are popular because of their low toxicity and environmental protection, and have broad application scenarios. The existing halogen-free flame-retardant ABS usually achieves the purpose of flame retardancy by adding about 30-50% of inorganic metal compou...

AI Technical Summary

Problems solved by technology

The existing halogen-free flame-retardant ABS usually achieves the purpose of flame retardancy by adding about 30-50% of inorganic metal compounds. There are differences in chemical properties and macroscopic physical forms between inorganic metal compounds and ABS, which cannot be effectively compatible with ABS. , there is a problem of poor compatibility between inorganic compounds and ABS, and a large proportion of powder filling is easy to disperse unevenly in the ABS material and cause powder agglomeration, which becomes a stress concentration point, thereby deteriorating the material performance. As a result, the material is prone to brittle cracks during processing and forming, and it is difficult to meet the use requirements
