Problems solved by technology

[0015] Its disadvantage is that the highest fire protection level is B1, and it is easy to generate an open flame when encountering high temperature, releasing a large amount of heat energy and generating dense black smoke
Once a fire breaks out, it can become a booster for the spread and expansion of the fire field, and it is restricted to use in many places with high fire protection requirements.
In summary, the urgent problem to be solved for wood-plastic flooring is to improve the fire protection level.

Embodiment 1

[0048] The preparation of embodiment 1 flame-retardant polyether

[0049] 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.

[0050] The catalyst is a mixture of 0.6 parts by mass of methanol, 0.5 parts by mass of silicone oil, 0.3 parts by mass of sodium silicate, and 0.1 parts by mass of sodium bicarbonate.

[0051] Rare earth fluoride (purchased from Yixing Xinweilicheng Rare Earth Co., Ltd., 2000 mesh) with mass parts of 1, 0.5, 1.5, and 1.5, 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 micr...

Embodiment 2

[0052] Preparation of embodiment 2 flame retardant polyether

[0053] Equipment and pressure control are the same as in Example 1.

[0054] 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.

[0055] Rare earth fluoride (purchased from Yixing Xinweilicheng Rare Earth Co., Ltd., 2000 mesh) with mass parts of 1, 0.5, 2.0, and 1.5, 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

[0056] The preparation of embodiment 3 flame-retardant polyether

[0057] Equipment and pressure control are the same as in Example 1.

[0058] 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.

Description

technical field [0001] The invention relates to the field of interior decoration materials, in particular to a class A polyvinyl chloride flame-retardant, fire-resistant and wear-resistant wood-plastic floor material. Background technique [0002] Wood-plastic flooring is a new type of environmentally friendly wood-plastic composite material product. The wood powder produced during the production of medium and high-density fiberboards is added to recycled plastics to make wood-plastic composite materials through granulation equipment, and then extruded into production groups. Made into wood-plastic flooring. The main material of wood-plastic outdoor flooring is polyvinyl chloride and wood powder or bamboo powder. After adding additives, mixing at high speed, granulating, and then using an extruder to extrude the pellets into molding materials, this type of floor can be used for garden landscape , villas and other outdoor platforms. The national standard for wood-plastic fl...
