Embodiment 1

[0039] Combine 35 parts by weight of flame retardant B, 10 parts by weight of smoke suppressant D, 50 parts by weight of chlorinated polyethylene (CPE), 5 parts by weight of polyethylene wax, 2 parts by weight of silane coupling agent and 0.3 parts by weight Parts of non-ionic antistatic agent, etc. According to the weight ratio of the formula, the above raw materials are fully mixed in a high-speed mixer, extruded and granulated, and then mixed with 100 parts by weight of polyvinyl chloride resin, and extruded on a twin-screw extruder , Injection molding samples, test performance. The results are shown in Table 3.

Embodiment 2

[0041] Except that the ethylene-acrylic acid copolymer is substituted for chlorinated polyethylene, the remaining components and process conditions are the same as in Example 1. The obtained samples were tested, and the results are shown in Table 3.

Embodiment 3

[0043] Except that oxidized polyethylene is used instead of polyethylene wax, the other components and process conditions are the same as in Example 1. The obtained samples were tested, and the results are shown in Table 3.

Abstract

The invention discloses a bulking-typed flame-proof smoke-resistant flexible-polychloroethylene composition and preparing method, which comprises the following parts: 100% polychloroethylene, 15-50% fire retardant, 3-25% smoke-resistant agent, 30-80% carrier resin, 0.1-20% dispersant, 0.1-10% coupler and 0.05-10% antistatic agent.

Description

Technical field [0001] The invention relates to a flame-retardant and smoke-inhibiting soft polyvinyl chloride composition and a preparation method thereof, belonging to the technical field of polymers, and in particular to an intumescent flame-retardant and smoke-inhibiting soft polyvinyl chloride composition and a preparation method thereof. Background technique [0002] Soft PVC has been widely used in various industries such as electronics, electrical appliances (wire and cable coating and insulation), construction, transportation, furniture and mining. As we all know, polyvinyl chloride resin itself has high flame retardancy, and its oxygen index (OI) can be higher than 45. However, as a soft PVC, a large amount of plasticizer is added in the processing process to improve the softness of the resin, so that the flame retardancy of the resin is greatly reduced, and it becomes a flammable material, which will spread when it catches fire. Chengda fire. In addition, the smoke ass...
