Abstract
The invention relates to water-based latex and a preparation method thereof and in particular relates to water-soluble latex for a polyvinyl chloride tape and a production method of the water-soluble latex. The water-based latex is prepared by mixing and reacting raw materials such as vinyl acetate, bi(2-ethylhexyl) maleate, 2-ethylhexyl acrylate, hydroxy-propyl acrylate, alkyl aryl polyoxyethylene ether, sodium ethylenesulphonate, acrylic acid, tertiary butanol, formyl sodium sulfonate, a ferrous sulfate solution, sodium acetate and running water. The latex adhesive tape is used for sealing packaging boxes, and the packaging boxes can be prevented from being damaged during opening, so that the packaging boxes can be recycled, and thus waste is avoided.
Description
Technical field
The present invention relates to a kind of latex and production method thereof.Specifically, be water-soluble latex and production method thereof for polyvinyl chloride rubber belt.
Background technology
At present, at packing, carrier, can often use the tape of tr.This tape is the most general with polyvinyl chloride rubber belt.Wherein, the latex using on tape is mostly water-insoluble latex.Owing to being water-insoluble latex, bond more firm, when unpacking, easily tr is damaged, tr cannot be recycled, serious waste phenomenon.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of latex.With the adhesive tape of this latex, carry out tr joint sealing, when unpacking, can avoid tr to damage, make the recyclable use again of tr, thereby avoided waste.
Another problem that the present invention will solve is to provide a kind of method of preparing latex.
For addressing the above problem, take following technical solution:
Water based emulsion feature of the present invention is the raw material that comprises following parts by weight:
490 ~ 510 parts of vinyl acetate between to for plastics;
240 ~ 260 parts of two (2-ethyl) esters of toxilic acid;
220 ~ 240 parts of Isooctyl acrylate monomers;
24 ~ 26 parts of Propylene glycol monoacrylates;
19 ~ 21 parts of alkylaryl Soxylat A 25-7s;
21 ~ 23 parts of sodium vinyl sulfonates;
24 ~ 26 parts, vinylformic acid;
9 ~ 11 parts of the trimethyl carbinols;
5 ~ 7 parts of formyl sodium sulfonates;
1.1 ~ 1.3 parts of copperas solutions;
0.3 ~ 0.5 part of sodium-acetate;
550 ~ 560 parts, tap water.
The content of described copperas solution is 1 % by weight.
The method characteristic of making described water based emulsion is to comprise the following steps successively:
First alkylaryl Soxylat A 25-7, sodium vinyl sulfonate, sodium-acetate, formyl sodium sulfonate, copperas solution and tap water are dropped in reactor, stir 18 ~ 20 minutes, mix, obtain mixed solution;
Then, described mixed solution is heated to 70 ~ 72 degrees Celsius;
Afterwards, under uniform stirring, added the two 2-ethyls of vinyl acetate between to for plastic, toxilic acid) ester, Isooctyl acrylate monomer, Propylene glycol monoacrylate, vinylformic acid and the trimethyl carbinol;
Finally, 70 ~ 72 degrees Celsius of lower copolyreaction 0.9 ~ 1.1 hour, obtain described water based emulsion.
Take above scheme, have the following advantages:
As can be seen from the above scheme, because latex of the present invention is water based emulsion, with the adhesive tape of this latex, carry out tr joint sealing, while unpacking, as long as packing bag is gone out to soak, just can easily adhesive tape be opened, not only avoided tr to damage, make the recyclable use again of tr, also can avoid waste.
