Problems solved by technology

[0004] On the other hand, the existing thermal insulation and decoration integrated boards are all composed of inorganic composite decorative layers plus organic flammable thermal insulation layers.
This kind of structure has low fire resistance, and the bonding part of the inorganic layer and the organic layer has different expansion coefficients due to different materials, so it is easy to separate and fall off in hot and cold environments, and the product life is not long.

Embodiment 1

[0036] Embodiment 1: Preparation of flame retardant polyether

[0037] 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.

[0038] 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.

[0039] Rare earth fluoride (purchased from Yixing Xinweilicheng Rare Earth Co., Ltd., 2000 mesh) with mass parts of 1, 0.5, 1.5, and 1.0, butylene oxide, catalyst, and polytetrafluoroethylene, at a temperature of 570 ° C, Under the reaction conditions of pressure of 75 MPa, voltage of 15,000 volts, and microwave frequency of 100 GHz, it was obtained ...

Embodiment 2

[0040] Embodiment 2: the preparation of insulation board

[0041] Equipment and pressure control are the same as in Example 1.

[0042] Catalyst is with embodiment 2. The mass parts are respectively 1, 0.5, 2.0, 0.5 lanthanum fluoride (purchased from Yixing Xinwei Licheng 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 90 GHz, it was obtained after 3 hours of reaction.

Embodiment 3

[0044] raw material:

[0045] Nucleating agent talcum powder 3 parts

[0046]Stabilizer barium stearate 4 parts

[0047] Flame retardant: 10 parts of hexabromododecane, 5 parts of tetrabromobutane, 4 parts of ammonium polyphosphate, 4 parts of melamine, 12 parts of flame-retardant polyether prepared in Example 1,

[0048] Charging agent 6 parts of quaternol,

[0049] Smoke suppressant molybdenum trioxide 5 parts,

[0050] Compatibilizer Maleic anhydride 3 parts,

[0051] Foaming agent Freon 2 parts.

[0052] Preparation:

[0053] see process figure 1 . (1) Put 100 parts of XPS into a kneader for internal mixing for 25 minutes, and control the melt temperature at 95°C. Add nucleating agent, smoke suppressant, char forming agent, stabilizer, phase solvent and flame retardant for mixing, continue banburying at 96°C for 11 minutes, take it out and use an open mill to form a tablet and crush it into granules for later use.

[0054] (2) Take 99 parts by mass of particles ob...

Abstract

The invention provides a manufacturing method for a polystyrene A-level non-ignitable building outer wall heat-preservation decorative plate. The manufacturing method includes the steps that (1) banburying is carried out on 100 mass parts of XPS for 20-30 minutes, nucleating agents, smoke suppression agents, charring agents, stabilizer, solvents and fire retardants are added and mixed, then banburying continues, and particles are obtained to be used; (2) 95-99 mass parts of particles are put into a foam extruder to manufacture plates; (3) sodium silicate is added into the other particles, banburying is carried out for 25 minutes, then the particles are put into a film applicator, the plates obtained in the second step are put into the film applicator, 15 kilos of pressure heat coating films are added, and film-coated plates are obtained. Organic XPS materials are manufactured through the method, are not ignitable when being fired, non-toxic, odourless, safe, environmentally friendly and high in weather resistance, have heat insulation and heat preservation performance, are as bright and smooth as ceramic tiles, and are free of decoration integration. The manufactured outer wall heat-preservation decorative plate extends the application field of outer wall heat-preservation decorative materials.

Description

technical field [0001] The invention belongs to the field of organic polymer compositions, and in particular relates to a preparation method of a polymer material with polystyrene as a base material and the obtained product. Background technique [0002] The thermal insulation integrated board is composed of adhesive layer, thermal insulation and decorative finished board, anchors, sealing materials and so on. At the same time, it has the functions of heat preservation and decoration. It is not only suitable for external wall heat preservation and decoration of new buildings, but also for energy saving and decoration renovation of old buildings; it is suitable for building heat insulation in cold regions and building heat insulation in hot regions.
