Embodiment 1

[0045] Example 1: Preparation of halogen-free environmentally friendly flame-retardant HIPS material

[0046] Put 65.8 parts by weight of HIPS514P, 26 parts by weight of aluminum hypophosphite, 6 parts by weight of melamine cyanurate, 1 part by weight of coupling agent JH-A110, 1 part by weight of EBS B50 and 0.2 parts by weight of SN80-SA7 into the high-speed Mix at high speed in the mixer for 3 minutes to obtain the mixed material, and then transport the mixed material to the twin-screw extruder through a precisely metered feeding device. The length-to-diameter ratio of the extruder is 30, and the screw speed is 300 rpm. Under the shearing, mixing, and conveying of the screw, the material can be fully melted, mixed, and then extruded, granulated, and dried to obtain halogen-free environmentally friendly flame-retardant HIPS material.

Embodiment 2

[0047] Example 2: Preparation of halogen-free environmentally friendly flame-retardant HIPS material

[0048] The HIPS514P of 63.4 parts by weight, the aluminum hypophosphite of 26 parts by weight, the melamine cyanurate of 6 parts by weight, the dipentaerythritol of 3 parts by weight, the SBS of 2 parts by weight, the JH-A110 of 1 part by weight, the EBS B50 of 1 part by weight and 0.2 parts by weight of SN80-SA7 are put into a high-speed mixer and mixed at high speed for 3 minutes to obtain a mixed material, and then the mixed material is transported to a twin-screw extruder through a precisely metered feeding device, and the temperature of each section of the extruder screw is controlled at Between 170 and 220°C, the length-to-diameter ratio of the twin-screw extruder is 30, and the screw speed is 300 rpm. Under the shearing, mixing, and conveying of the screw, the material is fully melted, mixed, and then extruded. Granulate and dry to obtain halogen-free, environmentally fr...

Abstract

The invention belongs to the technical field of HIPS (High Impact Polystyrene) materials and discloses a halogen-free environment-friendly inflaming retarding HIPS material as well as a preparation method and an application thereof. The material comprises the following components in percentage by mass: 45-65% of HIPS resin, 10-25% of hypophosphite, 2-13% of an auxiliary fire retardant, 1-10% of a toughening agent, 0.1-2% of a silane coupling agent and 1-5% of fillers. According to the halogen-free environment-friendly inflaming retarding HIPS material, the hypophosphite is added into the auxiliary fire retardant; polyol and a nitrogen-containing compound are used as a gas source and an acid source to have the synergic inflaming retarding effect and have small influences on mechanical properties; the silane coupling agent is used for carrying out surface treatment on the hypophosphite so that the hypophosphite and polymer resin have very good compatibility; other resin does not need to be added and the stable inflaming retarding can be realized; V-0-grade inflaming retarding can be realized. The halogen-free environment-friendly inflaming retarding HIPS material has good rigidity and impact resistance, good processability and good appearance, and can be widely applied to a thin-wall part.

Description

technical field [0001] The invention belongs to the technical field of HIPS materials, and in particular relates to a halogen-free environment-friendly flame-retardant HIPS material and a preparation method and application thereof. Background technique [0002] Hypophosphite has a high phosphorus content and good thermal stability. It has a good catalytic charcoal effect on organic polymers, and it can complement each other when used together with synergistic flame retardants to jointly improve the flame retardant performance. It is a valuable halogen-free and environmentally friendly flame retardant. [0003] Inorganic metal flame retardants have a great influence on the mechanical properties of materials. Halogen flame retardants will produce harmful gases during combustion, pollute the environment, and endanger human health. Hypophosphite flame retardants have better flame retardancy , has little effect on the mechanical properties of the material, is environmentally fri...
