Melt strength can be effectively increased by adding the aerogel compound into a resin system, effects of reinforcement, flame retardance, nucleation and the like are achieved, usage amount of a traditional flame retardant is reduced, porosity of the system can be effectively increased, resin foaming is facilitated, traditional flame retardant materials of molybdenum disulfide, diethyl phosphonate aluminum and the like are combined, and the lightweight polypropylene foaming composite material with good flame-retardant effect is finally prepared; the composite material is even in porosity, crush and heat resistant, resistant to wear corrosion, economic and durable and quite promising in application.

The invention discloses high-temperature good-strength quartz-based expendable pattern paint modified by mica powder. The high-temperature good-strength quartz-based expendable pattern paint is prepared from the following raw materials in parts by weight: 100-102 parts of quartz powder, 0.9-1.1 parts of modified starch, 0.9-1.1 parts of carboxymethyl cellulose, 2.4-2.6 parts of sodium bentonite, 0.9-1 part of mica powder, 0.8-0.9 part of tetrapod ZnO whiskers, 0.9-1.1 parts of silicasol, 10-13 parts of ethanol, an appropriate amount of water, 0.5-0.6 part of aluminum sol, 1.1-1.3 parts of nonionic boronates and 0.2-0.3 part of tea tree essential oil. The aluminum sol, the nonionic boronates and the tea tree essential oil are used, so that the bentonite is modified, the lipophilicity of the bentonite is improved, and the cohesiveness and the sagging resistance of the paint to plastic foams are improved; therefore, coatings are uniform and compact, molten steel is prevented from penetrating, the fissility is improved, and the aluminum sol and the nonionic boronates can form heat-resistant oxide after being heated, so that the high temperature strength of the coatings is improved.
