Problems solved by technology

[0002] At present, most of the flame retardant HIPS resins on the market are halogenated resins. This halogenated flame retardant resin contains harmful substances such as polybrominated diphenyl ethers that are harmful to the environment and human body, and does not meet the requirements of the European Union. There are very few resins, and the existing halogen-free flame-retardant HIPS resins still have the defects of high production cost, high product price and low product impact performance. This situation seriously hinders the development and development of halogen-free flame-retardant HIPS resins. application

Abstract

The invention belongs to the technical field of chemical industry and relates to a production formula and a preparation method for a halogen-free flame-retarding HIPS resin. The formula consists of an HIPS resin, a polyurethane resin, a thermoplastic elastomer (SBS) resin, microencapsulated red phosphorus, tritolyl phosphate, zinc borate, ethylene bisstearamide (EBS), calcium stearate, a silane coupling agent, titanium dioxide, an antioxidant 1010, an antioxidant 168, UV-770 and UV-327. The preparation method of the invention comprises the following steps of: adding the HIPS resin, the polyurethane resin, the SBS resin, the silane coupling agent, the tritolyl phosphate and the microencapsulated red phosphorus into a high-speed mixer in turn; starting the high-speed mixer for mixing for 5 to 10 minutes and then stopping the high-speed mixer; adding the zinc borate, the EBS, the calcium stearate, the titanium dioxide, the antioxidant 1010, the antioxidant 168, the UV-770 and the UV-327 into the mixer again in turn and uniformly mixing; and feeding into a twin-screw extruder to obtain the halogen-free flame-retarding HIPS resin. The resin has the characteristics of high flame retarding performance, high impact strength and low production cost, and has high market competitive power.
