Abstract

The invention relates to a preparation method of a ceramic composite modified resin coated EPS foam flame-retardant thermal-insulation material. The method comprises steps as follows: (1) a resin material, ceramic forming filler, a fluxing agent and a dispersing agent are evenly mixed under the stirring condition and ground until the fineness is smaller than or equal to 100 mu m, and composite modified resin is obtained; (2) a curing agent is added, the mixture is evenly mixed, and a flame-retardant coating agent is obtained; (3) EPS pre-foam particles are added, the mixture is mixed, and surfaces of the EPS pre-foam particles are evenly coated with the flame-retardant coating agent; (4) the EPS pre-foam particles coated with the flame-retardant coating agent are placed in a mold, water vapor is introduced for secondary foaming, curing is performed, and the material is obtained. The preparation steps are simple and easy to implement, and raw materials are easy to obtain.

Description

technical field [0001] The invention relates to a preparation method of a composite modified resin-coated EPS foam flame-retardant thermal insulation material, in particular to a preparation method of a ceramizable composite modified resin-coated EPS foam flame-retardant thermal insulation material, which belongs to the technical field of chemical building materials. Background technique [0002] Polystyrene (EPS) foam insulation material has the advantages of small thermal conductivity, low water absorption, small bulk density, good thermal insulation performance, good mechanical strength and toughness, excellent dielectric properties, corrosion resistance and easy molding and high productivity. has been widely applied. However, the biggest disadvantage of polystyrene resin is that it has a low oxygen index, is extremely flammable, and has more melt droplets and higher smoke density. With the improvement of people's living standards and fire safety awareness, there are hig...
