Problems solved by technology

The disadvantage of this material is that polyvinyl acetate must be dissolved into a solution with methanol, and because polystyrene particles are easy to stick, it is necessary to spray ethylene glycol stripping agent when stirring to make polystyrene become independent particles; Vinyl ester does not have the property of being curable when heating or adding a curing agent, so the amount of flame retardant added is limited, and the product will deteriorate during molding and cannot be combined or cured; in addition, toxic, Flammable methanol and ethylene glycol are volatile and have adverse effects on the health of workers and the environment

Abstract

The invention discloses a manufacturing method of a heat preservation material with excellent fireproof performance. The heat preservation material is prepared from a mixture of graphene, zirconia, alumina and polystyrene. The manufacturing method of the heat preservation material comprises the following steps of graphene preparation; graphene-zirconia-alumina composite material preparation; anti-flaming heat-preservation mixture preparation; heat preservation material preparation. Compared with the prior art, the heat preservation material has better flame retardancy and low smoke density, is toxity-free and pollution-free, has a higher fireproof grade and accords with an environment protection requirement.

Description

technical field [0001] The invention relates to a building material, in particular to a building insulation material. Background technique [0002] In this field, the widely used thermal insulation material is expandable polystyrene. Polystyrene, molecular formula C 8 h 8 , mainly used for foam molding, as thermal insulation, heat insulation, shockproof and packaging materials. Polystyrene is foamed into spherical particles, which is a foam. The foam is light in weight and has good heat insulation performance. It can be added to cement materials and mixed with cement, and dried in the sun to prepare lightweight building materials. It has heat preservation, fire prevention, waterproof, etc. performance. However, because polystyrene has the characteristics of flammability, large amount of smoke, many drips, and amorphous viscous liquid after burning, the combustion level is not high, and it does not meet the requirements of the current high fire resistance level of wall ma...
