Embodiment 1

[0035] Example 1 Preparation of flame retardant polyether

[0036] 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.

[0037] 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.

[0038] 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 microwave f...

Embodiment 2

[0039] Example 2 Preparation of flame retardant polyether

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

[0041] 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.

[0042]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

[0043] Example 3 Preparation of flame retardant polyether

[0044] Equipment and pressure control are the same as in Example 1.

[0045] 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 flame-retardant artificial leather material, which is prepared from the following raw materials in parts by weight: 60-80 parts of polyvinyl chloride, 2-4 parts of melamine, 9-15 parts of tetrabromobisphenol A, and molybdenum trioxide 1‑3 parts, 10‑15 parts of hexabromocyclododecane, 0.2‑0.7 parts of ferrocene, 15‑20 parts of zinc borate, 2.5‑6 parts of plasticizer, 6‑10 parts of expandable graphite, 2 parts of cosolvent ‑5 parts, flame retardant polyether 15‑19 parts, color masterbatch 0.6‑1.8 parts, brominated epoxy resin 7‑9 parts, ammonium polyphosphate 1‑3 parts, coupling agent 0.1‑0.3 parts. The material is environmentally friendly and energy-saving, non-absorbent, non-combustible, wear-resistant, simple process, good dimensional stability, good compression creep resistance, and has reached the A level of GB 50222-95 "National Standard of the People's Republic of China for Building Interior Decoration Design Fire Protection Code" Fire standards.

Description

technical field [0001] The invention relates to the field of interior decoration materials, in particular to a polyvinyl chloride flame-retardant imitation leather material. Background technique [0002] Imitation leather is made of PVC, PU and PU with different formulas, such as foaming or filming, on a textile or non-woven fabric base. Gloss, patterns, etc. require processing, and it has the characteristics of a wide variety of colors, good waterproof performance, neat edges, high utilization rate and relatively cheap price compared with genuine leather. It is a kind of material that has been very popular in the early days until now, and is widely used to make various leather products, or some genuine leather materials. The surface is very delicate, can be flawless, and more durable. It is widely used in automobiles, furniture and household. [0003] Because most of the materials are inflammable, the fire scene becomes a source of smoke, toxic gas and heat energy. This...
