Embodiment 1

[0029] The flame-retardant polyether of this embodiment is composed of the following raw materials: 1 part of rare earth fluoride, 0.5 parts of butylene oxide, 1.5 parts of catalyst, and 1.5 parts of polytetrafluoroethylene; wherein, 1.5 parts of catalyst is composed of the following components: 0.6 parts Methanol, 0.5 parts of silicone oil, 0.3 parts of sodium silicate, 0.1 parts of sodium bicarbonate.

[0030] The preparation method of flame retardant polyether in the present embodiment comprises the following steps:

[0031] (1) Put the fluoride, butylene oxide, catalyst, and polytetrafluoroethylene of the proportioning amount into a cylindrical airtight reaction vessel (arc generator is set in the reaction vessel, and microwave is set at the 1.5m height of the reactor wall. Generator), after vacuuming, fill it with non-oxidizing gas, so that the pressure in the container is 75MPa;

[0032] (2) Under the conditions of a temperature of 560°C, a voltage of 15,000 volts, and ...

Embodiment 2

[0034] The difference between this embodiment and embodiment 1 is that the fluoride used in embodiment 2 is sodium fluoride.

Embodiment 3

[0036] The difference between this embodiment and embodiment 1 is that in embodiment 3, 3 parts of polytetrafluoroethylene are selected for use.

Abstract

The invention relates to the field of materials, in particular to a polyvinyl chloride grade-A fireproof material. The polyvinyl chloride grade-A fireproof material is prepared from the following constituents in parts by weight: 70-85 parts of PVC, 15-20 parts of expansible graphite, 10-15 parts of borax, 35-50 parts of hexabromocyclododecane, 15-25 parts of zinc borate, 13-18 parts of magnesium hydroxide, 13-20 parts of fire-retardant polyether, 8-12 parts of a carbon forming agent, 0.01-0.10 part of a stabilizer, 4-10 parts of a plasticizer, 3-8 parts of antimonous oxide, 3-8 parts of a phase solvent, 0.05-0.30 part of a coupling agent, and 13-18 parts of aluminum hydroxide. The polyvinyl chloride fireproof material provided by the invention can be up to grade A, has dampproof and mildewproof functions when being processed and molded to form a plate, a sheet, a tube stock, a sectional material or a foam material, meanwhile has thermal insulation and sound insulation properties, is free of oil paint, non-combustible, not afraid of burning, convenient to process, environment-friendly, and non-pollution, and further has various processing characteristics of the wood.

Description

technical field [0001] The invention relates to the field of materials, in particular to a class A polyvinyl chloride fireproof material and a preparation method thereof. Background technique [0002] Polyvinyl chloride is one of the plastic products with the largest output in the world. It is cheap and is a material with a wide range of uses. It is often used in our lives, such as PVC pipes, PVC floors, PVC wallpapers, PVC furniture, PVC leather, PVC interior decoration boards, sheets, profiles, etc. Adding different additives according to different uses, PVC plastics can exhibit different physical and mechanical properties. Adding an appropriate amount of plasticizer to polyvinyl chloride resin can make a variety of hard, semi-rigid, soft and transparent products. [0003] After searching, it was found that the invention patent application with publication number CN104072904A discloses a polyvinyl chloride plastic, including the following raw materials in parts by weight...
