Title: Improvements in and relating to compositions for waterproofing cement and allied materials
IPC: C04B41/49
Filed: 1952-02-05
Abstract: A composition for water-proofing cement or concrete comprises (1) an oil-modified alkyd resin and (2) a polysiloxane resin cold-blendable and compatible with the alkyd resin and obtained by hydrolysing a mixture of organohalogeno-silanes having a R/Si ratio from 1:1 to 2:1 with a hydrolysing medium consisting of water and a liquid halogenated hydrocarbon which is a solvent for the silanes and the formed siloxane, has a S.G. above 1.1 and a B.P. below 175 DEG  C., and is inert to the silanes, the formed siloxane and to any formed hydrogen halide, the polysiloxane resin comprising from 5 to 50 per cent by weight of the total weight of (1) and (2).  The alkyds may be made by condensation of one or more polyhydric alcohols, e.g. ethylene, diethylene, propylene, and dipropylene glycols, glycerine, pentaerythritol and sorbitol, with one or more polycarboxylic acids or anhydrides, e.g. oxalic, malonic, succinic, adipic, tricarballylic, phthalic, isophthalic, terephthalic, diphenic and naphthalic acids, and modified with (raw, heated or blown) linseed, rapeseed, cottonseed, chinawood, castor, dehydrated castor, soyabean and oiticica oils, coconut fatty acids and fatty acid glycerides. Additional examples of reactants are given in Specification 635,286. The alkyds may be further modified by monohydric alcohols boiling above 150 DEG  C., e.g. methyl and butyl ethers of diethylene glycol, and by monocarboxylic acids, e.g. benzoic acid.  In making the compositions the alkyd and polysiloxane resins are dissolved in a solvent or solvent mixture, e.g. xylene, toluene, benzene, mineral spirits, petroleum spirits and butanol, to give, for example, a solids content of 1 to 25 per cent by weight.  Curing catalysts such as those given in Specification 597,834, [Group IV], may be added, e.g. in amount of 0.01 to 5 per cent by weight of the total resin solids, the preferred ones being the naphthenates of lead, cobalt and calcium and the octoates of zinc and other metals.  In examples: (1) a spraying solution was made by mixing together a xylene solution of monophenyl-, dimethyl-, diphenyl-siloxane copolymer, a linseed oil fatty acid modified glyceryl phthalate in petroluem spirits, cobalt and calcium naphthenates, mineral spirits, and xylene, and sprayed on to concrete slabs (1, 2, 3) and stucco panels (4).  The siloxane resin of Example (1) was made by mixing a blend of methyltri-, phenyltri-, dimethylmono- and diphenyldi-chlorosilanes with trichloroethylene and slowly adding the resulting solution to water at 35 DEG  C. by means of an inlet tube which dipped below the surface of the water; the mixture was then allowed to separate into layers, the lower non-aqueous layer being removed and stripped of solvent.  Other solvents specified are tetrachloroethane, tetrachloroethylene, carbon tetrachloride, ethyl bromide, dichloropropane-1,3, dichloropropylene, 1,2-dibromo-2-methylpropane, tri-chlorobromomethane, acetylene tetrachloride, chlorobenzene, bromobenzene, meta-dichlorobenzene and bromocyclohexane.
