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.
[0016] To sum up, the problem to be solved urgently for wood-plastic interior decoration materials is to improve the fire protection level.

[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.

Abstract

The invention provides a polyvinyl chloride A-grade fire-retardant interior decoration material. The polyvinyl chloride A-grade fire-retardant interior decoration material is prepared from the following raw materials in parts by weight: 60-80 parts of polyvinyl chloride, 3-5 parts of melamine, 15-25 parts of wood powder, 1.1-2.2 parts of molybdenum trioxide, 8-11 parts of tetrabromo-bisphenol-A, 0.5-1.0 part of dicyclopentadienyl iron, 13-27 parts of hexabromocyclododecane, 2-5 parts of a plasticizer, 10-22 parts of zinc borate, 2-5 parts of a cosolvent, 20-40 parts of hydroxide, 0.6-1.8 parts of colour masterbatch, 10-15 parts of flame-retardant polyether, 30-60 parts of calcium carbonate, 5-10 parts of sodium carbonate, 5-9 parts of ammonium polyphosphate, 5-9 parts of brominated epoxy resin and 10-15 parts of expanded graphite. The polyvinyl chloride A-grade fire-retardant interior decoration material is environment-friendly and energy-saving, does not absorb water and is non-combustible and wear-resistant, the process is simple, the dimensional stability is good, and anti-compression creep property is good; meanwhile, the A-grade fire prevention standard in the national standard, Code for Fire Prevention in Design of Interior Decoration of Buildings, of the People's Republic of China GB 50222-95 can be met.

Description

technical field [0001] The invention relates to the field of interior decoration materials, in particular to a class A polyvinyl chloride fire-resistant and flame-retardant interior decoration material. Background technique [0002] Wood-plastic interior decoration material 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 It is produced and made into wood-plastic interior decoration materials. The main material of wood-plastic outdoor flooring is polyvinyl chloride and wood powder or bamboo powder. After adding additives and mixing at high speed, it is granulated, and then the extruder is used to extrude the pellets into molding materials. Wood-plastic composite interior decoration material is a kind of wood (wood cellulose, plant cellulo...
