To provide a silicone mist suppressing agent capable of providing a composition and a cured product which are excellent in silicone mist suppressing effect and storage stability. The present inventionprovides the silicone mist suppressing agent comprising at least one kind of powder selected from an organic powder, an inorganic powder, and an inorganic / organic composite powder each having a volume-average particle diameter in the range of 100-4000 nm. The present invention also provides a solventless silicone composition which contains an organopolysiloxane having a viscosity in the range of25-50,000 mPa s at 25 DEG C and further contains the silicone mist suppressing agent in an amount of 0.1-10 pts.mass based on 100 pts.mass of the organopolysiloxane.

The invention relates to a rigid polyurethane foam material, in particular to a high-performance rigid polyurethane foam material containing epoxide group, which is characterized by being prepared by the reaction of the following components: isocyanate with 28-32wt% of NCO, polyalcohol compound with the OH value of 300-800, epoxy resin with the epoxy equivalent weight more than 100, catalyst compound, foam stabilizer and water, wherein the isocyanate component at least contains polyaryl polymethylene isocyanate; the polyalcohol compound at least contains polyalcohol component taking tolylenediamine as initiator; and the catalyst compound at least contains imidazole derivative catalyst, tertiary amine catalyst and organo-metallic catalyst. The rigid polyurethane foam material has high strength and super toughness as well good size stability, maintains excellent mechanical performance at higher temperature, and can be applied to wood-imitation material, filling material, thermal insulation material and the like.

The invention relates to a dry-type transfer-printed textile and a preparation method of the dry-type transfer-printed textile. The method comprises the following steps: uniformly dispersing a water-dispersible hot melt adhesive into water so as to form a suspension; adding a printing thickener so as to regulate the viscosity of the suspension; adding printing auxiliaries such as acid, alkali and a hygroscopic agent according to the used dye, so as to prepare printing paste; coating a paper sheet or s film by use of the printing paste; drying and calendering, so as to obtain a paper sheet or film with the coating surface; performing printing treatment on the paper sheet or the film by use of a dye, so as to prepare transfer paper or a transfer film; hot-pressing and laminating the transfer paper or transfer film and a to-be-printed textile; performing color fixing, then stripping off the transfer paper or transfer film, and washing and sizing the textile after the color fixing, so as to obtain the printed textile. According to the printing method provided by the invention, wetting treatment of the textile is omitted, and transfer printing can be directly performed on the dry textile or a garment, so that the definition of printed patterns and the transfer stability of the dye are ensured; meanwhile, the operation sequence is simplified, emission of waste water of the printing and dyeing industry can be reduced, and the preparation method is beneficial to energy conservation and environment protection.

The present invention provides a water-based ink composition for writing instruments, which includes at least 5 mass % or more of resin particles with a volume basis median diameter D50 of 0.3 μm or more and 0.05 to 10 mass % of butylene glycol·ethylene. Alcohol copolymer, wherein the aqueous ink composition is excellent in drying resistance without reducing the dispersion stability of the resin particles, and the aqueous ink composition is suitable for writing instruments such as water-based ink ballpoint pens and markers.
