Description
Technical field
The preparation method containing epoxy group and vinyl-silane-copolymer that the present invention relates to a kind of belongs to fine chemical technology neck
Domain.
Background technique
Silane coupling agent is a kind of organo-silicon compound containing organic group and inorganic group, and general structure is Y-R-Si
(OX)3, wherein Y is functional activity group, R is the alkyl group of linkage function, X is hydrolyzable methyl, ethyl, acyloxy
Equal groups；During production and application, for Y active group in conjunction with corresponding organic material, Si-OX is then hydrolyzed to Si-OH and nothing
Machine material surface-OH dehydrating condensation is in conjunction with inorganic material, therefore silane coupling agent plays in the material " molecular bridge " work
With good connection organic material and inorganic material.The Y active group of epoxy silane coupling and vinyl silicane coupling agent
Respectively epoxy group and vinyl, epoxy group can be copolymerized with epoxy types well in use with open loop, and ethylene
Base can be with unsaturated ethylene linkage or acetylene bond addition copolymerization, therefore these two types of materials are chiefly used in epoxide resin material and polyacrylic
In column material.
Acrylic resin paint is excellent with weather resistance, the bright hardness of paint film is high, guarantor's light unfading is excellent, chemically-resistant
The good advantage of performance, the development and application in terms of top-grade building coating for wall surface was very fast in recent years.In coating for wall surface in use, due to
Acrylic resin paint resin is inadequate to the adhesive force and permeability of the inorganic material such as cement, stone, to avoid this disadvantage from applying
Work is frequently with epoxy infiltration and as priming paint seal coat, then coating under fluorine carbon of constructing, and finally imposes acrylic acid top-coat work
For upper coating.Its construction method is cumbersome and long construction period, particularly use fluorine-resin coating cost are compared with therefore, these are lacked
Point limits the development of application of the acrylic resin paint in building trade.
To avoid these disadvantages, patent CN109111811A is using epoxy resin modified acrylic resin and combines construction skill
The adhesive force of art raising acrylic resin paint；Patent CN108300053A in acrylic resin is formulated by adding methyl silicon
Oily and other addition agent aids are prepared into Powdery propylene acid resin coating and directly smear in wall.The above method is from different ways
Diameter reduces the defect of acrylic resin paint in the application, but improved effect is not particularly significant.
Summary of the invention
It is an object of the invention to: it provides a kind of easy to use, low in cost and acrylic resin paint can be significantly improved
In the preparation method containing epoxy group and vinyl-silane-copolymer of the adhesive force of wall.

Expect that time control in 2-3h, continues aging reaction 1-2h after being added dropwise；
3), sampling analysis after aging reaction 1-2h, until water content drops to 0.05% hereinafter, obtaining, epoxy group silicon without in for reaction
The polymer alcoholic solution of alkane；
4), vinyl silanes and alkoxysilane polymer are made by different proportions in method using step 1), 2), 3) respectively
Alcoholic solution；Wherein the molar ratio of silane and water is n:n-1, and n is the degree of polymerization of counter structure unit, and catalyst is anhydrous tetraboric acid
Sodium, the dosage of catalyst are the 0.1-0.4% of silane quality；
5) vinyl silanes obtained are mixed with the alcoholic solution of epoxy radicals silicone hydride polymer, after cooling to 1-10 DEG C, water is added
Mixing, obtains, homogeneous mixture, and keeps the temperature the tetraalkoxy silicon that it is slowly equably added drop-wise to step 1) in this temperature range
It in the reactor of alkane polymer solution, while improving mixing speed and polymerization reaction is hydrolyzed to 500-600r/min, control is anti-
Answering temperature is 50-60 DEG C, wherein the molar ratio of water and tetraalkoxysilane polymer is (2.0-2.1): 1；
6) alcohol, after completion of the reaction, is isolated by the method for distillation, the catalyst separated out after distillation is separated by filtration, obtains, contains ring
Oxygroup and vinyl-silane-copolymer finished product.
It is described to be A containing structural unit, B containing epoxy group and vinyl-silane-copolymer molecular formula and C is constituted by any suitable
The terpolymer of sequence straight chain and branched structure:
Wherein, R is (C1-C4) alkyl, and O, P, q are the positive integers of 2-10.
In order to make hydrolytic-polymeric reaction activity is moderate to generate with the polymerization for reducing product ring structures in above-mentioned preparation method,
Use sodium tetraborate as the catalyst of hydrolytic-polymeric reaction, and reacts and further subtracted using four one-step hydrolysis polymerization control mode
The silane copolymer of cyclic structure generates in few product.
The beneficial effects of the present invention are:
1, product of the present invention is the backbone containing siloxy, epoxy group and vinyl groups, is applied as acrylic resin
Feed additives using when can with wall inorganic material, epoxy resin primer and acrylic resin by chemical reaction blend,
To improve the adhesive strength of three boundary layers, the using effect of coating is improved.
2, compared with traditional acrylic resin paint construction, which is directly mixed in bottoming in epoxy resin primer,
Acrylic acid top-coat can be directly smeared later as upper coating, coating under the expensive fluorine carbon that do not need to construct, therefore construct
Material cost is low with cost of labor to be substantially reduced and short construction period.
3, substance of the invention in use, when figure layer crosslinking curing only a small amount of alcohol release, therefore gas when using
Taste is small, small pollution of the environment.
4, the preparation method of the product of the invention technique and equipment is simple, reaction condition is mild, industrialized production easy to accomplish.
