Abstract
The invention discloses a kind of modification acrylate pressure-sensitive adhesive emulsions and preparation method thereof.The acrylic acid ester emulsion uses amino silane for coupling agent and maleic anhydride modified function monomer.The emulsion preparation method is that first acrylate vinyl monomer, anion emulsifier, initiator, alkenes monomer, modified function monomer, coupling agent are added to obtain pre-emulsion A into water, it is added to the water initiator, nonionic emulsifier and pH buffer to obtain solution B, appropriate A is added into B, it is warming up to solution blueing light and obtains seed emulsion C, it is warming up to reaction temperature, remaining A is added dropwise in seed emulsion C, 40 DEG C of left and right adjusting pH, cooling discharge are cooled to after dripping 1~3h of reaction.The lotion introduces amino silicane coupling agent, maleic anhydride function monomer participates in modified copolymer, and Environmental Safety, the adhesive article of preparation has many advantages, such as non yellowing, high peeling force, while fracture elongation, tensile strength greatly improve.
Description
Technical field
The present invention relates to a kind of Acrylate pressure-sensitive adhesive emulsions, and in particular to a kind of modification acrylate pressure-sensitive adhesive emulsion and
Preparation method.
Background technique
Currently, domestic similar widely used Acrylate pressure-sensitive adhesive emulsion is mainly by vinyl monomer, functional monomer, crosslinking
Monomer contains (APEO) induced by alkyl hydroxybenzene) emulsifier, initiator, pH value adjustment agent and water composition, the pressure sensitive adhesive warp of generally existing production
Many deficiencies such as the easy xanthochromia of high temperature, fracture elongation, tensile strength and peel strength difference.In recent years, for its disadvantage, Ren Mentong
It crosses a variety of new methods and approach is modified it, its performance is made to have obtained larger raising, application is more extensive.
The combination of acrylic acid ester emulsion emulsifier uses emulsifier for octyl, nonyl phenol anion, nonionic etc., is especially containing
In the presence of induced by alkyl hydroxybenzene emulsifier, in the destruction of human body and adjacent species (fish) endocrine system.Foreign countries have set about limiting
System emulsifier containing induced by alkyl hydroxybenzene uses in the product.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of modification acrylate pressure-sensitive adhesive emulsion, acrylate creams
Liquid introduces maleic anhydride modified function monomer, amino silicane coupling agent participates in modified copolymer.
Thus the technical solution adopted by the present invention is that: the present invention by weight, 45~52 parts of vinyl monomer, anion cream
1~2 part of agent, 0.5~1.2 part of nonionic emulsifier, 1.0~1.5 parts of methacrylic acid, acrylic acid in alkenes monomer
1.5~2 parts of hydroxy ester, 0.2~0.5 part of amino silane, 0.2~0.5 part of maleic anhydride, 0.1~0.5 part of persulfate,
0.03~0.1 part of pH buffer, 40~50 parts of deionized water.
A kind of preparation method of modification acrylate pressure-sensitive adhesive emulsion, follows the steps below:
1) first by acrylate vinyl monomer, anion emulsifier, initiator, alkenes monomer, modified function list
Body, coupling agent, which are added, obtains pre-emulsion A into water；
2) initiator, nonionic emulsifier and pH buffer are added to the water to obtain solution B, by 6%~12% in step 1
The A of weight is added into B, is warming up to solution blueing light and obtains seed emulsion C；
3) 85 ± 2 DEG C of reaction temperature are warming up to, remaining A is added dropwise in seed emulsion C, 2~3h of time for adding is added dropwise
36~45 DEG C of adjusting pH are cooled to after complete 1~3h of insulation reaction to neutrality, cooling discharge；
The modified function monomer is maleic anhydride, coupling agent is amino silane.
Coupling agent is phenylaminomethyl trimethoxy silane, phenylaminomethyl triethoxysilane any one or two kinds of groups
It closes.
Anion emulsifier used in polymerized emulsion is neopelex, methylpropenyl sodium sulfonate, dodecyl
Any two kinds of the mixture of sodium sulphate；Nonionic emulsifier is fatty alcohol polyoxyethylene ether.
Vinyl monomer include butyl acrylate, Isooctyl acrylate monomer, in methyl methacrylate any two kinds or two kinds with
On mixture.
Initiator is ammonium persulfate or sodium peroxydisulfate, and pH buffer is sodium bicarbonate, and pH adjusting agent is ammonium hydroxide.
The alkenes monomer is methacrylic acid, any one or two kinds of combinations in crylic acid hydroxy ester.
The crylic acid hydroxy ester is hydroxy-ethyl acrylate, the hydroxypropyl acrylate combination of any one or two kinds.
2) in the step, the hybrid mode of described A, B use following form:
One container mixed for described A, B is provided, draws two branch pipes on the container, A, B pass through the branch pipe respectively
The container is flowed into, the flow control of A, B are less than 5s completely into the time difference of container in the two.
The container is formed with flowering structure: i.e. bottom surface is recessed arc-shaped；
Two branch pipe merges into a supervisor in container, and A, B pass through branch pipe respectively and flow to supervisor's mixing, subsequently into
It is mixed in container, the supervisor has structure diagonally downward；
The structure for delaying A, B to fall is provided in the supervisor, the structure is that the supervisor is a reducer pipe,
One is formed in the middle part of the supervisor and reduces section, two sides formation expanding reach, and supervisor's inner wall forms several salient points.
The invention has the advantages that 1) acrylic acid ester emulsion introduces maleic anhydride modified function monomer, amino silane
Coupling agent participates in copolymerization, contains phenyl ring and amido bond in product emulsion, provides not only the anchoring affinity to organic and inorganic substrate
Power, under the harsh conditions of substrate immersion, adhesive force adhesive strength is all dramatically increased, and is allowed to the adhesive article prepared fracture
Elongation percentage, tensile strength, peel strength greatly improve.
2) the acrylic acid ester emulsion pre-emulsion uses anion emulsifier neopelex, methylpropenyl sulfonic acid
Any two kinds of combinations are used as pre-emulsion emulsifier in sodium, lauryl sodium sulfate；Seed emulsion is using nonionic emulsifier fat
Alcohol polyoxyethylene ether combination production Acrylate pressure-sensitive adhesive emulsion.Not only have stability good, particle diameter distribution is narrow, easy to control etc. excellent
Point, and be free of alkyl phenol emulsifier, more environmentally-friendly, high temperature gluing non yellowing.
3) adding manner of A, B of the present invention make the mixing of the two, reaction, blend each other more by the way of gradually mixing
To be uniform, the further present invention is made that corresponding restriction to the structure of supervisor using supervisor, the structure type of branch pipe,
So that A, B are more fully mixed the quality for uniformly guaranteeing product.
