The aqueous PUR dispersion is prepared according to the following steps:
(i) it will be fitted into the container for being furnished with thermometer, blender by the polyether polyol being dried, be added into container
Toluene di-isocyanate(TDI) is simultaneously passed through nitrogen in 30-50 DEG C of reaction 30-60min, is then added dropwise into container dissolved with dihydroxymethyl third
The n-methyl-2-pyrrolidone of acid obtains performed polymer in 55-60 DEG C of reaction 1-2h；
(ii) deionized water and triethylamine high-speed stirred are added in another container, (i) performed polymer obtained is cooled to by step
It is injected after 40 ° wherein, dihydroxypropane and ethylenediamine chain extension is added after reacting 5-10min, dispersion reaction 15-18min is available
Aqueous PUR dispersion；
Specific step is as follows for the preparation method of the styrene-butadiene latex:
Butadiene, styrene, polyoxyethylene phenol alkyl ether, tert-dodecyl mercaptan are added in reaction kettle, are 70-75 in temperature
Polymerization reaction 6-7h at DEG C, is then cooled to room temperature, adds sodium phosphate, odium stearate, potassium peroxydisulfate stirring 20-30min, i.e.,
Obtain styrene-butadiene latex；
Wherein, the styrene and butadiene mass ratio are 2.5-3:1, wherein purity >=99% of styrene；The phosphorus
Sour sodium, odium stearate, potassium peroxydisulfate mass ratio are 0.3-1:1.5:0.3；
Specific step is as follows for the preparation method of the carboxylic styrene butadiene latex:
Styrene, butadiene, water and part benzoyl peroxide are added in reaction kettle, after vacuum nitrogen gas displacement,
Starting stirring opens heating simultaneously, mixing speed 300-400r/min, when reaction kettle is warming up to 75-80 DEG C, addition remainder
The benzoyl peroxide divided after reacting 30-50min, is added the aqueous solution of methyl methacrylate and ammonium persulfate, keeps the temperature 2-3h
After be cooled to room temperature, adjust viscosity≤300mPa.s, pH value: 7-9 is to get arriving carboxylic styrene butadiene latex；
Wherein, the benzoyl peroxide of the addition is added in two portions, and the 1/3 of total amount is added for the first time, second of addition total amount
2/3；
Specific step is as follows for the preparation method of the styrene-acrylic latex:
(1) by styrene, Isooctyl acrylate monomer, acrylic acid, N hydroxymethyl acrylamide, neopelex, vinyl
Pre-emulsification kettle, the strong stirring 15- at 700-800r/min is added in sodium sulfonate, octyl phenol polyoxyethylene ether and deionized water
30min is prepared into pre-emulsion；
(2) part pre-emulsion in part ammonium persulfate, sodium bicarbonate and above-mentioned steps (1) is added in reaction kettle, rapidly
It is warming up to 80-85 DEG C, mixing speed 80-100r/min, keeps the temperature 30-50min, then remaining pre-emulsion and persulfuric acid is added dropwise
Ammonium drips in 1-2h, and temperature is controlled at 70-75 DEG C, drips rear temperature and rises to 80-85 DEG C, keeps the temperature 0.5-1h, finally drop
For temperature to 45 DEG C, ammonium hydroxide adjusts pH to 7-8 to get styrene-acrylic latex is arrived.
2. the chinampa Adhesive composition according to claim 1 haveing excellent performance, it is characterised in that: the crosslinking
Agent is epoxy silane crosslinker XR-500, trien, hexamethylenetetramine, one in aziridines crosslinking agent XR-100
Kind or several mixtures；The coupling agent is one or both of aqueous silane coupling agent and aqueous titanic acid ester coupling agent；Institute
Stating anti-aging agent is p phenylenediamine type antioxidant；The ultraviolet absorber is phenyl salicylate, trimethoxybenzoate, benzene oxygen
One of base triazine；The defoaming agent is one or more of octanol, tributyl phosphate, silicone mixture；Described
Dispersing agent is one or more of lauryl sodium sulfate, methyl anyl alcohol, polyacrylamide and polyethylene glycol mixture.
