摘要:
Water-dispersible aqueous compositions comprise a solvated alkali-metal C 1 -C 4 hydrocarbyl siliconate, a solvated organosilicon component derived from an organosilicon compound, and an aminosilicon component derived from an aminosilane. The organosilicon compound may comprise at least one hydrophobic group such as a phenyl group, an organic group with a carbon chain having more than three carbon atoms, or at least one fluoroalkyl group. The aminosilicon component may comprise at least one amino-terminated hydrocarbon group. Methods for forming the water-dispersible compositions comprise solvating the organosilicon compound and the aminosilane in an aqueous solution containing at least one alkali-metal C 1 -C 4 hydrocarbyl siliconate. Substrates such as brick, masonry, concrete, and wood may be treated with the aqueous compositions to form a hydrophobic sealing layer on the substrate surface, resistant to staining and to permeation by water and optionally oleophobic and resistant to permeation by oil and oil based staining.
摘要:
A process and product for increasing the flame resistance and thermal insulation properties of chemically treated substances, in some cases providing the treated substance with flame resistance at temperatures higher than 1800 DEG C (direct fire), with no limit to the time of exposure. A number of embodiments of flame resistant compositions are discussed herein but all embodiments include a mixture containing water, inorganic acids, ammonium salts, sodium carbonate and pyrophosphate and, in some instances other constituents. The disclosed process treats substances to prevent the generation of any flames. The substances that have successfully been tested with the disclosed process include cloth (natural and synthetic), rugs and carpets, wood, cardboard, and paper. However, it is believed that this process can be applied to an umlimited number of flammable cellulose substances. With respect to the treatment of cloth, another advantage asserted for the disclosed process is that the texture and colors of the treated cloth are minimally affected, if at all. The cloth will not look or feel hard, thick or tough. Furthermore, the chemical treatment of the cloth will last through six months of domestic washing. A further application of the disclosed invention is as a coating on foam, particularly polyurethane foam and laminated foam. Applying the disclosed invention to foam material results in a resistance to all fire, not just an impedance to the flame for a limited period of time as known in the prior art. An even further application of the disclosed invention is as an additive to paint, resulting in an increase in the paint's tolerance to fire. This increase in thermal resistance would necessarily be transferred to any articles coated with said paint.

This invention relates to a treating composition containing 0.3 to 30 % by weight of a fluoroaliphatic radical containing poly(oxyalkylene) compound, 0.3 to 30 % by weight of an anti-soiling agent and 0 to 60 % by weight of an environmentally acceptable water-miscible organic solvent and water for the use for imparting excellent water- and oil repellency, stain resistance and dry soil resistance to textiles, carpets, concrete, paper, leather and wool.
摘要:
Method for impregnating in depth wooden boards, sections or planks with plastic materials, comprising the treatment of the wood, preferably pre-dried and optionally, first under vacuum conditions and then under pressure conditions, with an impregnation solution comprised of the plastic materials in organic solvents during a period of time sufficient to allow the impregnation of the wood with said solution, said impregnation being possibly carried out by osmosis with solutions in organic solvents of said thermoplastic materials and polymerisable thermostable materials, particularly in the case of panels of any type faced with sheets of noble woods by means of urea-formol or phenol-formol.
