Problems solved by technology

[0003] The honeycomb structure of EPS foam determines its performance, but also because of its internal pore structure, it has high air circulation and continuously supplies oxygen, resulting in high combustion rate, large heat release, and serious dripping. , large amount of smoke, not easy to self-extinguish and other problems
[0004] In addition, EPS foam will also appear in the modification process. While improving the flame retardancy, its mechanical properties and thermal insulation properties will decrease, which hinders its popularization and use in the construction field.

Abstract

The invention belongs to the field of construction, and discloses a self-extinguishing EPS foam plastic and a house. The house is formed by assembling a plurality of EPS foam plastic modules, and compared with a traditional house prepared from wood or reinforced concrete materials, the house prepared from the self-extinguishing EPS foam plastic has the advantages of being low in construction cost,saving more energy sources, resisting the vibration, insulating heat and sound, not rotting, not rusting, being light and convenient and the like; the labor is reduced by 60%, the construction time is reduced by 50%, the construction cost is reduced by 30%, and the requirements of green construction, environmental protection and high efficiency are met.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a preparation method of self-extinguishing EPS foam plastics and a house made of self-extinguishing EPS foam plastic modules. Background technique [0002] EPS is used in packaging and construction industries because of its excellent properties, such as waterproof, heat insulation, excellent dielectric properties, and good mechanical properties. But it is an organic hydrocarbon with an oxygen index of only 18.0%, which is a flammable material. Even if the fire source is removed, it can still continue to burn. During the burning process, it is accompanied by thick smoke and obvious shrinkage, and there is molten dripping with open flames. [0003] The honeycomb structure of EPS foam determines its performance, but also because of its internal pore structure, it has high air circulation and continuously supplies oxygen, resulting in high combustion rate, large heat release,...
