Abstract
The invention discloses a formula for modified polyvinyl acetate and a preparation process. According to the formula, the modified polyvinyl acetate is prepared from the following components in percentage by weight: 10-16 percent of polyvinyl alcohol, 12-18 percent of vinyl acetate, 1.5-3.5 percent of dibutyl phthalate, 0.01-0.5 percent of an emulsifier OP-10, 0-0.3 percent of sodium bicarbonate, 0-0.5 percent of acrylic acid, 10-20 percent of starch, 0.1-3 percent of a thickening agent, 0.01-0.1 percent of an initiating agent and the balance of water. The starch is reacted with a vinyl acetate-ethylene copolymerization emulsion, and a saponified rosin is taken as the thickening agent, so that the modified polyvinyl acetate is low in cost, is environmentally friendly, is simple in the process, and has very strong bonding force on wood and paper.
Description
Technical field
The present invention relates to a kind of modified polyvinyl acetate emulsion, relate to particularly a kind of formula and manufacture craft that timber and paper is had to a modified polyvinyl acetate of very strong cohesive force.
Background technology
Vinyl acetate between to for plastic, because it has the two keys of C=C on molecular structural formula, chemical property is more active, industrially generally by vinyl acetate between to for plastic and polyvinyl alcohol, add emulsifying agent, polymerization generates polyvinyl acetate emulsion, but because the polyvinyl acetate emulsion of cattail wool is at raw materials cost, the problem such as rate of drying and tack is difficult to be applicable to some different requirements, for addressing these problems, generally after a polymerization, adds not by filler and the starch of chemical reaction again.Because the proportion between raw material is different, material is different, therefore exists a shortcoming, and stability can not get ensureing, therefore in using, be no more than three months layering just occurs, precipitation, mouldy.
Summary of the invention
The object of the present invention is to provide formula and the manufacture craft of a kind of with low cost, good stability, a tacky modified polyvinyl acetate.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of formula of modified polyvinyl acetate, be by weight percentage: polyvinyl alcohol 10-16%, vinyl acetate between to for plastic 12-18%, dibutyl phthalate 1.5-3.5%, emulsifier op-10 0.01-0.5%, sodium bicarbonate 0-0.3%, vinylformic acid 0-0.5%, starch 10-20%, tackifier 0.1-3%, initiator 0.01-0.1%, surplus is water.
Preferably, described emulsifying agent is the condenses of alkylphenol and oxyethane.
Preferably, described initiator is ammonium persulphate.
Preferably, described tackifier are saponification rosin.
A manufacture craft for modified polyvinyl acetate, the step of its feature is:
(1) in reactor, add water 500kg, polyvinyl alcohol 70kg, rising temperature for dissolving;
(2) be cooled to below 60 ℃, add vinyl acetate between to for plastic 80kg, dibutyl phthalate: 12kg, sodium bicarbonate 0.5kg, emulsifying agent 1kg, vinylformic acid 1.6kg, initiator 0.3kg;
(3) rising temperature for dissolving, after condenser refluxes, slowly drips vinyl acetate between to for plastic, makes vinyl acetate-ethylene copolymerization emulsions;
(4) add starch 50kg, react with vinyl acetate-ethylene copolymerization emulsions, make modified polyvinyl acetate emulsion, then add tackifier reaction, adjusting viscosity.
Beneficial effect of the present invention: compared with prior art, the present invention utilizes starch to react with vinyl acetate-ethylene copolymerization emulsions, utilizes saponification rosin for tackifier, with low cost, environmental protection, technique are simple, and timber and paper are had to very strong cohesive force.
