Copolymer; terpolymer (SAG) formed by copolymerization of styrene, acrylonitrile and glycidyl methacrylate. One or two or more compatibilizers are used together. The 3D printing composite material prepared by the invention is non-toxic and environment-friendly, has superior comprehensive performance, and has broad market prospects and application value.

The invention discloses an auxiliary heating tube. The auxiliary heating tube comprises a stainless steel main body; the outer surface of the stainless steel main body is provided with a protective layer in a sintering way; and the protective layer is prepared from the following components in parts by weight: 4.3 parts of styrene, 1.2 parts of glycidyl methacrylate, 0.5 part of a titanate, 0.9 part of sodium propionate, 0.2 part of magnesium oxide and 1.3 parts of 3-chloro-2-hydroxypropyl trimethyl ammonium chloride. Because the outer surface of the stainless steel main body is provided with the corrosion, scale, heat and oxidation resistant high-hardness protective layer in a sintering way, the auxiliary heating tube has long service life.

The invention discloses a high-toughness anti-cracking rubber material for a sealing ring. The high-toughness anti-cracking rubber material for the sealing ring is prepared by using the following raw materials in parts by weight: 100 to 120 parts of ethylene propylene diene monomer rubber, 5 to 10 parts of methyl vinyl silicone rubber, 60 to 80 parts of white carbon black, 2 to 4 parts of zinc oxide, 0.15 to 0.25 part of dibenzoyl peroxide, 1.5 to 2.5 parts of sulfur S80, 1.5 to 2.5 parts of anti-aging agent MB, 0.3 to 0.5 part of accelerator TMTD, 1 to 2 parts of ethyl cellulose, 2 to 4 parts of methyltrimethoxysilane, 0.5 to 1 part of tetrabutyl titanate, 0.15 to 0.25 part of titanate coupling agent NDZ-401, 6 to 8 parts of nano-graphite powder, 4 to 6 parts of castor oil and 0.5 to 1 part of glycidyl methacrylate. The rubber material disclosed by the invention has good wear resistance and long-lasting friction-reducing performance, simultaneously has high toughness and good anti-cracking performance, is long in service life, is good in sealing performance and is suitable for being used as a sealing ring material.

The invention relates to anti-corrosion acrylic acid epoxy resin powder paint for ceramic. The paint comprises the following raw materials: glycidyl methacrylate, polyol, azobisisobutyronitrile, monoacid, di-tert-butyl peroxide, dicyclopentadiene, an initiator, maleic anhydride, epoxy resin, zinc oxide, a flatting agent, 1-o-tolylbiguanide, dodecanedioic acid, 2-mercaptobenzothiazole and titanium dioxide. According to the paint, the melting point is 200-220 DEG C, the density is 135-145g/cm<3>, and the paint has no abnormity after being soaked in 5% hydrochloric acid solution for 20-30d; the glossiness is 140%-150%, and after the artificial accelerated aging is implemented for 500h, the gloss retention rate is 94-98%; the shore hardness is 50-70H, the drying time is 20-30min, the paint cannot bubble or crinkle after being soaked in saturated calcium hydroxide for 15-35d, and the scrubbing resistance times are 1800-2200.

The invention discloses an epoxy group containing polysilsesquioxane sulfonate, and a preparation method and applications thereof. The preparation method comprises following steps: a, a mercapto trialkoxysilane monomer is added into an aqueous solution containing an anionic surfactant and an alkali catalyst for reaction; b, after reaction in step a, with stirring, under ultraviolet lamp illumination, p-styrene sulfonate, glycidyl methacrylate, and 1-hydroxycyclohexyl phenyl ketone are added successively; c, after reaction in step b, solid liquid separation is carried out so as to obtain a solid product; and d, the solid product obtained in step c is subjected to washing and drying so as to obtain a finished product. According to the preparation method, grafting of the sulfonate and the epoxy groups onto the polysilsesquioxane chains of the epoxy group containing polysilsesquioxane sulfonate is adopted, so that the compatibility with PC is excellent, dispersion is convenient, migrationresistance is achieved, pollution is less, and an extremely low adding amount is capable of improving PC flame resistance grade to be UL94V-0 grade (1.6mm), and the durability is excellent.
