摘要:
The reaction product obtained by cohydrolysis and condensation of (A) a fluorinated alkyl-bearing alkoxysilane, (B) an amino-bearing alkoxysilane, and (C) an alkoxysilyl-bearing polyorganosiloxane is dissolved in water to provide a water-soluble, water/oil repellent treating composition. This water/oil repellent treating composition has improved water solubility and shelf stability, has no detrimental effects on the environment because of the aqueous system, and imparts fully durable water repellency and satisfactory softness and hand to textiles.

A method for preparing a vehicle interior material comprises the steps of feeding 100 parts by weight of phosphorus and nitrogen-containing non-halogen flame retardant particles and 0.1 to 20 parts by weight of hydrophobic inorganic oxide fine particles having hydrophobic groups and having an average particle size of 0.001 to 5 μm to a mixer equipped with a high-speed agitation means having a revolution capability of about 100 to 5,000 rpm, agitating and mixing the phosphorus and nitrogen-containing non-halogen flame retardant particles and the hydrophobic inorganic oxide fine particles to produce the phosphorus and nitrogen-containing non-halogen flame retardant particles coated with the hydrophobic inorganic oxide fine particles, mixing 100 parts by weight as solids of a synthetic resin emulsion and 1 to 300 parts by weight of the phosphorus and nitrogen-containing non-halogen flame retardant particles coated with the hydrophobic inorganic oxide fine particles to produce a coating composition, coating the coating composition onto the vehicle interior material, and drying the coated vehicle interior material.
摘要:
A flame retardant additive comprises (A) a gassing agent which is a compound containing both phosphorus and nitrogen, typically ammonium polyphosphate, which is surface coated with (B) a silicone-base water repellent treating agent comprising a co-hydrolytic condensate obtained through co-hydrolytic condensation of (i) an organosilicon compound and (ii) an amino group-containing alkoxysilane or a partial hydrolyzate thereof in the presence of an organic or inorganic acid. The additive is improved in moisture absorption resistance and dispersion and suited for use in resins or elastomers.
摘要:
A silicone emulsion composition for wood treatment is prepared by emulsifying and dispersing (A) an organopolysiloxane, (B) the reaction product of an amino-containing organoxysilane and an acid anhydride, (C) an epoxy-containing organoxysilane, (D) colloidal silica and/or polysilsesquioxane, and (E) a curing catalyst in water to form a silicone emulsion, and adding and mixing (F) a boron compound with the silicone emulsion.
摘要:
A wood preservative composition comprising an aqueous preservative and 0.001-1.0 wt % of a polyether-modified silicone having a specific structure is provided. The polyether-modified silicone reduces the surface tension of the composition and helps the preservative penetrate deeply into the wood interior.
摘要:
An aqueous water repellent useful in the treatment of substrates of lignocellulose-origin materials or the like is characterized by comprising the product of co-hydrolytic condensation of (A) 100 parts by weight of an organosilicon compound having the formula: (R1)a(OR2)bSiO(4-a-b)/2 (1) wherein R1 is alkyl, R2 is alkyl, 0.75≦a≦1.5, 0.2≦b≦3 and 0.9
摘要:
Coating compositions comprising (a) an organosilicon compound obtained by the hydrolysis in water of a hydrolyzable mixture of specific hydrolyzable silanes or their partial hydrolyzates, (b) water, and (c) a microparticulate photooxidation catalyst, substantially reduce or eliminate the amount of organic solvent required. In addition, these coating compositions provide applied films having good weather resistance and antifouling properties, and are themselves stable even at an alkaline pH.
摘要:
A silicone emulsion composition for wood treatment is prepared by emulsifying and dispersing (A) an organopolysiloxane having at least two SiH groups, (B) a surfactant, and (C) a curing catalyst in water to form a silicone emulsion, and adding (D) a boron compound to the silicone emulsion.
摘要:
A coating composition comprising 100 pbw as solids of a synthetic resin emulsion and 1-300 pbw of a non-halogen flame retardant in which P and N-containing non-halogen flame retardant particles are surface coated with hydrophobic inorganic oxide fine particles is applicable to vehicle interior materials.
