Amido functional group polysiloxane and composition based on the same

Abstract

The invention relates to an amino functional polysiloxane with formulas III and IV, a preparation method thereof and the use as a binder, and the composite based on the amino functional polysiloxane, in particular to the stable chloride-free composite of polysiloxane acidic salt and the preparation and use thereof. The R<1> and R<2> are independent and are respectively expressed by R<1> as -(CH2) pAr<1>, -(CH) pAr<1>, -(CH) pAr<1>-(CHCH2) or -(CH2) pAr<1>-(CHCH2) and / or R<2> as -(CH2) qAr<2>, -(CH) pAr<2>, -(CH) pAr<2>-(CHCH2) or -(CH2) pAr<2>-(CHCH2)-, wherein, p is equal to or more than 0 and equal to or less than 8, q is equal to or more than 0 and equal to or less than 8, and Ar<1> and Ar<2> correspond to aryl, aralkyl or aralkenyl, and n is equal to or more than 1 and equal to or less than 8, m is equal to or more than 1 and equal to or less than 8, Y is the same or different and represents alkoxyl or oxhydryl or O1 / 2; A is inorganic or organic acidic residue and actually exists as T-structure unit, and a is equal to or more than 0 and equal to or less than 2, b is equal to or more than 0 and equal to or less than 1, c is equal to or more than 0, c<*> is equal to or more than c, (a+b) is equal to or more than 0 and equal to or less than 3 and x is equal to or more than 2. The amino functional polysiloxane is also used as the binder between inorganic and organic surfaces or used in the process of coating organic polymer to inorganic surfaces, and the thickness of amino functional polysiloxane layer is less than 800nm.

Description

Technical field:

[0001] The present invention consists in aminofunctional polysiloxanes, their preparation and use as binders, and compositions based on aminofunctional polysiloxanes, in particular polysiloxane acid salts with low chloride content Stable composition, method for its preparation and use thereof. Background technique:

[0002] Known, such as 3-(N-vinylbenzyl-2-aminoethyl)aminopropyltrimethoxysilane or 3-(N-benzyl-2-aminoethyl)aminopropyltrimethoxysilane Acid salts of functionalized aminosilanes can be used as binders. The use of polyolefins or epoxy resins as binders in the coating of metals, preferably copper and iron, is reported in US4902556, EP353766 and US4849294. According to EP338128, WO8800527, US4499152, US4382991, US4330444, DE2802242 (be applicable to the binder of various resin systems on the glass fiber), EP-A-0845040 or BE845040 (for the binder of the epoxy resin on the flat glass and The technical solution of improving alkali resistance) can r...
