Description
Technical field
The invention belongs to the synthetic methods that chemical industry synthesis field more particularly to a kind of acrylic pressure-sensitive adhesivee stick agent.
Background technique
Pressure-sensitive adhesive agent (pressure sensitive adhesive, PSA) is one kind from gunk-squeeze process, it is smaller
Active force under, more firm bonding force can be formed.The bonding that pressure-sensitive adhesive agent is formed between two articles surface is advocated
If Van der Waals force, therefore, after bonding plane is formed, the structure of gluing of surfaces is not destroyed.In general, pressure-sensitive during the bonding process
Glue is sensitive to pressure, but after bonding plane is formed, pressure sensitive adhesive is then insensitive to pressure.Since it is easy to use, after opening
The surface of adherend is not generally influenced, therefore is widely used.Pressure-sensitive adhesive agent, which is normally applied product mainly, sticking tape, gluing
Label, gluing hook etc., have wide range of applications.Medical adhesive plaster, electric appliance work friction tape of early stage etc. all belong to pressure-sensitive adhesive
Product has been generalized to the fields such as packaging office appliance, medical material, electronic apparatus, coating protection, communications and transportation.It is pressure-sensitive
The general structure of sticking tape, common substrate have plastic film, paper, metal foil, thin slice etc..
Acrylate pressure-sensitive adhesive (APSA) can be divided into the kinds such as solvent type, emulsion-type and light-cured type.Solvent type pressure
Quick adhesive environmental pollution is serious, should try to recycle；Emulsion-type pressure-sensitive poor water resistance, moisture-proof is bad, is coated with dry speed
Degree is slow, should be improved.
Summary of the invention
For the above-mentioned problems of the prior art.The present invention provides a kind of synthesis side of glutinous agent of acrylic pressure-sensitive adhesivee
Method；The glutinous agent water resistance of the acrylic pressure-sensitive adhesivee that this method obtains is strong, and moisture-proof is good, and coating rate of drying is fast.
To achieve the goals above, a kind of acrylic pressure-sensitive adhesivee provided by the invention sticks the synthetic method of agent, specific to wrap
Include following steps.
Butyl acrylate, vinylacetate, acrylic acid, methylol acryloyl are weighed with electronic balance in step 1, vent cabinet

Step 2 weighs lauryl sodium sulfate, OP, potassium peroxydisulfate, sodium bicarbonate and 60-100g with electronic balance
In ionized water mixing, 300-450r/min electromagnetic agitation 10-15min, dissolution sufficiently, obtains uniform aqueous solution.
Step 3 weighs mix monomer in step 1 with electronic balance and the aqueous solution in step 2 is added and stirs with machinery
It mixes, in the four-hole boiling flask of thermometer and feed opening, is gradually warming up to 70 with heating mantle under 300-500r/min speed of agitator
DEG C -75 DEG C, isothermal reaction 30min.
Step 4 is warming up to 80-85 DEG C, be added dropwise to simultaneously respectively under constant temperature with constant pressure funnel remaining mix monomer and
Aqueous solution uniformly instills, and instilling time control is 3 hours or so.
Step 5 drips off mix monomer and aqueous solution, is warming up to 80-90 DEG C, after isothermal reaction 30-40min, is cooled to 20-
34 DEG C or less.
Step 6 pours out polyacrylate dispersion from four mouthfuls of reaction flasks, in the beaker, weighing, observation appearance, whether there is or not
Agglomeration.
Brown paper is cut into 19cm × 30cm rectangle by step 7, is fixed on RK automatic coating machine, selects No. 7
Bar (film is with a thickness of 80 μm), pressure sensitive adhesive is coated on brown paper；With the hot wind of hair dryer to the polyacrylic acid ester gum smoothened
Liquid is dried, cooling after drying.
The butyl acrylate, vinylacetate, acrylic acid, hydroxymethyl acrylamide and lauryl mercaptan weight
Than for 5:2:1:0.08.
The lauryl sodium sulfate, OP, potassium peroxydisulfate, sodium bicarbonate weight ratio be 3:7:3:3.2.
Aqueous solution weight ratio in mix monomer and step 2 in the step 3 in step 1 is 1:3.
Remarkable result of the invention.
The pressure sensitive adhesive characteristic obtained using preparation method of the present invention is superior, carries out just glutinous and holds glutinous effect very two lines；Its
In, it is just glutinous to refer to that adhesive contact substrate moment to the tackifying ability on surface, use rope touching method or rolling ball method measurement.We use
Be rolling ball method measurement；Hold the glutinous tackifying ability referred to after adhesive contact substrate long-time to surface；However for general
For polyacrylate water-borne pressure sensitive adhesive, original viscosity and holds stickiness and mutually restrict, and it is mutual for holding stickiness and cohesive force
It is corresponding, they mainly by pressure sensitive adhesive polymerization process soft monomer and hard monomer ratio and type determine.And pressure of the present invention
The original viscosity of quick glue is good, also better to the effect of impregnation of substrate surface, sticks together effect and is also apparent from.
