Embodiment 1

[0031] Embodiment 1: Preparation of flame retardant polyether

[0032] A cylindrical airtight reaction vessel with a height of 2 meters, an arc generator is arranged in the reaction vessel, and a microwave generator is arranged at a height of 1.5m on the wall of the reactor. Before the reaction starts, the container is filled with nitrogen and carbon dioxide (volume ratio 100:1.5) after vacuuming, so that the pressure in the container is 75MPa.

[0033] The catalyst is a mixture of 0.8 parts by mass of methanol, 0.7 parts by mass of silicone oil, 0.5 parts by mass of sodium silicate, and 0.3 parts by mass of sodium bicarbonate.

[0034] Rare earth fluoride (purchased from Yixing Xinweilicheng Rare Earth Co., Ltd., 2000 mesh) with mass parts of 1, 0.8, 2.3, and 3.0, butylene oxide, catalyst, and polytetrafluoroethylene at a temperature of 560 ° C and a pressure It is obtained after 3 hours of reaction under the reaction conditions of 75MPa, voltage of 15,000 volts, and microwa...

[0035] Embodiment 2: Preparation of flame retardant polyether

[0036] Equipment and pressure control are the same as in Example 1.

[0037] The catalyst is a mixture of 0.7 parts by mass of methanol, 0.6 parts by mass of silicone oil, 0.5 parts by mass of sodium silicate, and 0.2 parts by mass of sodium bicarbonate.

[0038] Rare earth fluoride (purchased from Yixing Xinweilicheng Rare Earth Co., Ltd., 2000 mesh) with mass parts of 1, 0.5, 2.0, and 2.0, butylene oxide, catalyst, and polytetrafluoroethylene at a temperature of 550 ° C and a pressure It is obtained after 3 hours of reaction under the reaction conditions of 75MPa, voltage of 15,000 volts, and microwave frequency of 100GHz.

Embodiment 3

[0039] Embodiment 3: Preparation of flame retardant polyether

[0040] Equipment and pressure control are the same as in Example 1.

[0041] Catalyst is with embodiment 2. The mass parts are respectively 1, 0.5, 2.0, 1.5 lanthanum fluoride (purchased from Yixing Xinweilicheng Rare Earth Co., Ltd.), butylene oxide, catalyst, and polytetrafluoroethylene at a temperature of 550 ° C and a pressure of 75 MPa. Under the reaction conditions of a voltage of 15,000 volts and a microwave frequency of 100 GHz, it was obtained after 3 hours of reaction.

Abstract

The invention provides a polystyrene flame-retardant resin which is prepared from the following components in parts by mass: 70-80 parts of polystyrene, 8-15 parts of char forming agent pentaerythritol, 10-15 parts of borax, 0.01-0.5 part of stabilizing agent, 20-30 parts of hexabromocyclododecane, 10.6 parts of French chalk, 18-25 parts of zinc borate, 4-8 parts of cosolvent, 20-40 parts of hydroxide, 0.6-1.8 parts of color master batch, 10-20 parts of flame-retardant polyether, 4-8 parts of antimony trioxide, 15-20 parts of expandable graphite, 0.1-0.5 part of coupling agent, 8-15 parts of wood meal, 8-12 parts of sucrose and 5-10 parts of rutile titanium white. The test result indicates that the polystyrene flame-retardant resin satisfies Grade A in Classification for Burning Behavior of Building Materials and Products GB 8624-2006 and Grade A in Chinese Code for Fire Prevention in Design of Interior Decoration of Building GB5022-95.

Description

technical field [0001] The invention belongs to the field of flame-retardant materials, and in particular relates to a flame-retardant organic polymer material composition and a preparation method thereof. Background technique [0002] Polypropylene (PPE) is a copolymerized rubber with ethylene and propylene as the basic monomers. It is often used in the manufacture of household products, pharmaceutical packaging, building material fillers, or electrical equipment housings. The fire rating of building materials is directly related to the life safety of residents, and providing polymer materials with high fire ratings is a problem that material producers must pay attention to. [0003] The working temperature of polypropylene is usually below 80°C, and its high temperature resistance and fire resistance limit the scope of application. [0004] The utility model patent CN2937735Y proposes a flame-retardant thermal insulation board, which uses polypropylene as a filling materi...
