Embodiment Construction

[0005] The preparation method of the green environment-friendly flame-retardant ABS alloy of the present invention is: the ABS / PVC system has an "island" structure, PVC and SAN form a continuous phase together, and the rubber particles in the ABS are used as a dispersed phase during the blending process, and its particle size is basically no Variety. When the material is impacted by an external force, the rubber particles become stress concentration points, causing the material to induce crazes, and at the same time, the rubber particles can disproportionate, terminate crazes or induce new crazes, thereby improving the impact resistance of the material.

[0006] The fluidity of the ABS / PVC blend system is worse than that of ABS, and the thermal stability of PVC is not good. During the processing, it is prone to degradation due to thermal shear force, so an appropriate amount of heat stabilizer and lubricant should be added to the blend system. agent. Commonly used thermal sta...

Abstract

The invention discloses a composite material of green environment protective flameproof ABS alloy and making method, which is composed of ABS and PVC, wherein fitful quantity of heat stabilizer and lubricant are added into co-blending system, which improves flameproof property with fire retardant within Sb2O3 and halogen fire retardant; the composite material reinforces extending property, bending property and hinging property, which improves mechanic strength and electric property obviously.

Description

Technical field: [0001] The patent of the invention belongs to the field of polymer composite materials, and relates to a green and environmentally friendly flame-retardant ABS alloy composite material and its preparation method. The invention increases the application range of ABS resin and has good economic and social benefits. Combustion ABS alloy composite material and preparation method thereof. Background technique: [0002] ABS resin usually refers to the graft copolymer of polybutadiene rubber and monomer styrene and propylene, which has impact resistance, high rigidity, oil resistance, low temperature resistance, chemical resistance, excellent mechanical strength and electrical properties and other characteristics, but the flame retardant performance of ABS is not good. The way to obtain green and environmentally friendly flame retardant ABS is to add an appropriate amount of flame retardant polymer PVC to ABS, which can not only reduce the amount of inorganic flame...
