Abstract
The invention discloses a water-soluble paper plastic which comprises acrylic acid, acrylic acid butyl ester, vinyl acetate ester, sodium hydroxide, initiator, adhesion promotor, compound emulsifying agent and deionized water. The performance indexes of the paper plastic is that the appearance is in the shape of ivory uniform viscous emulsion, the solid content is 42-56 percent, the viscosity is 1000 mPa/s, thr curing time is 50-70 s, the pH value is 6-7, and the storage period is 6 months. The water-soluble acrylate emulsion adhesive has the characteristics of low cost, non-toxicity, convenience in use, easiness in mechanized operation and equipment cleaning, and the like, and has remarkable economical and social benefits.
Description
Technical field
The present invention relates to adhesive field, particularly relate to a kind of water-soluble plastic cement.
Background technology
At present there are a lot of problems in the tackiness agent for the trade mark made of paper of pasting plastic packaging containers, as the poor adhesion to plastics with water base adhesives such as polyvinyl alcohol, Mierocrystalline celluloses, with chloroprene rubber, urethane equal solvent type tackiness agent, cost is high, toxicity is larger, paper composite gum prepared as main body by the acrylate of take, though have nontoxic, incombustible advantage, dry rear high molecular polymer is water insoluble, clean container and equipment difficulty etc.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of water-soluble plastic cement, can solve the problems such as poor adhesion, the toxicity of papery trade mark tackiness agent is large, water insoluble.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of water-soluble paper plastic cement is provided, and composition comprises: vinylformic acid, butyl acrylate, vinyl acetate, sodium hydroxide, initiator, tackifier, compound emulsifying agent, deionized water; The performance index of described water-soluble paper plastic cement are: the even viscous emulsion of appearance milky white, solid content 42～56%, viscosity 10000 mPas, set time 50～70s, pH value 6～7,6 months storage periods.
In a preferred embodiment of the present invention, the consumption proportion of vinyl acetate and butyl acrylate is 1.1～1.2:1.
In a preferred embodiment of the present invention, described initiator is water-soluble persulphate, and consumption is 1%.
In a preferred embodiment of the present invention, the consumption of described tackifier is 2～5%.
In a preferred embodiment of the present invention, the consumption of described compound emulsifying agent is 2～5%.
The invention has the beneficial effects as follows: a kind of water-soluble plastic cement of the present invention, it is a kind of water-soluble acrylic ester class emulsion adhesive, have cost low, nontoxic, easy to use, be easy to realize the characteristics such as mechanized operation, equipment easy cleaning, significant economic and social benefit is arranged.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
The embodiment of the present invention comprises:
1) a kind of water-soluble paper plastic cement, main component used comprises:
Vinylformic acid, butyl acrylate, vinyl acetate, sodium hydroxide, initiator, tackifier, compound emulsifying agent, deionized water
2) preparation method's step:
By butyl acrylate 100kg, vinyl acetate 110～120kg, polarity Acrylic Acid Monomer 50kg, compound emulsifying agent 4.2～4.4kg, deionized water 1000kg mix pre-emulsification, mixture after pre-emulsification is put into to the reactor of belt stirrer and thermometer, stirring is warming up to 72～80 ℃, add the water-soluble persulfate initiator of 2.2kg, after reacting and being incubated 2h, be cooled to 40～50 ℃ in reactor, stirring adds appropriate sodium hydroxide, and the pH value of regulating emulsion adhesive is 6～7.
3) performance index of the water-soluble paper plastic cement of preparation are as stated above:
The even viscous emulsion of appearance milky white;
Solid content 42～56%;
Viscosity 10000 mPas;
