Description
Technical field
The present invention relates to butyronitrile latex field, the preparation method of the butyronitrile latex burr solution needed for especially a kind of butyronitrile glued membrane plucking thorn.
Background technology
The finger of oil resistant wearing gloves, the centre of the palm and the back of the hand place all make anti-skidding burr usually, and this burr can increase the frictional force of gloves, plays the effect of conveniently picking up object, use instrument and preventing article from dropping.Need during current plucking thorn to use butadiene-acrylonitrile rubber plucking thorn solution, this solution adds certain particle size rubber powder and makes in adhesive special (matching with butadiene-acrylonitrile rubber glued membrane), this Binder Properties is stable, associativity is strong, difficult drop-off, but this special binding agent is expensive, and need import, a large amount of use can cause product cost to increase, and finally makes product be on a sticky wicket in the cut-throat competition in market.
A lot of technician thinks the substitute products of use butyronitrile latex solution as adhesive special at present, but butyronitrile latex stability of solution is poor, rubber powder is easily reunited, can cause that the burr of product surface is uneven, profile unsightly, poor product quality, the shortage market competitiveness.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can reduce production cost, improve enterprise competitiveness, ensure the preparation method of stable butyronitrile latex burr solution needed for butyronitrile glued membrane plucking thorn that product design is attractive in appearance.
The present invention solves its technical problem and is achieved through the following technical solutions:
A preparation method for butyronitrile latex burr solution needed for butyronitrile glued membrane plucking thorn, is characterized in that: comprise the following steps:

(2) dispersant solution of 25-35% rubber powder, step (1) prepared and water mix and are stirred well to and mixes, leave standstill 4-6 hour, again mixing solutions is stirred, vulcanized rubber powder is soaked and reaches complete dispersion state, then mixing solutions is left standstill one day;
(3) butyronitrile latex is slowly poured in mixing solutions obtained in step (2) on one side, stir, make the rubber powder of dispersion be distributed in butyronitrile latex solution better, leave standstill 12-24 hour, be butyronitrile latex burr solution.
And the dispersion agent described in step (1) is polyoxyethylene nonylphenol ether or fatty alcohol-polyoxyethylene ether.
And the hot water described in step (1) is 80 DEG C, the water mixed with rubber powder and dispersant solution in step (2) is the hot water of 90 DEG C.
And use handheld electric stirrer to stir in step (2), stirring velocity is 750rpm.
And the weight ratio of the dispersant solution of rubber powder, 25-35%, water and butyronitrile latex is 10: (0.7 ~ 1): (8 ~ 10): 65.
And, after butyronitrile latex and mixing solutions stir in step (3), need covered with plastic film on container in standing period, in case surface-moisture evaporates and solidifies.
And, need agitator to be stretched in butyronitrile latex burr solution before the use of butyronitrile latex burr solution and stir, rubber powder granule in surperficial air supporting is distributed in solution once again, forms uniform solution and eliminate the bubble floated, obtained bubble-free, rubber powder disperse homogeneous solution.
Advantage of the present invention and beneficial effect are:
1, this preparation method adopts butyronitrile latex solution to substitute traditional special butadiene-acrylonitrile rubber binding agent, because butyronitrile latex solution price is low, easily obtains and without import, therefore significantly can reduce production cost, bring great convenience to manufacturer.In addition, butyronitrile latex is directly used can also to improve the oil-proofness of finished product gloves.
2, this preparation method uses dispersion agent to carry out surface treatment to rubber powder, and the vulcanized rubber powder after process is wetting, good dispersity, avoid reuniting, thus has ensured gloves good looking appearance, and the burr that its surface pulls out is evenly distributed.
3, the dispersion agent selected in this preparation method is polyoxyethylene nonylphenol ether or fatty alcohol-polyoxyethylene ether, and these two kinds of dispersion agents have good emulsifying, dispersion, wettability, can be made into good and stable emulsion.This dispersion agent cost is low, significantly can reduce the production cost of enterprise, the market competitiveness of improving product after putting into production.And this dispersion agent free from extraneous odour, safety and sanitation, meet related request.
4, the present invention is the preparation method of the butyronitrile latex burr solution needed for a kind of reasonable in design, technique simple butyronitrile glued membrane plucking thorn, this preparation method adopts butyronitrile latex to substitute special butadiene-acrylonitrile rubber binding agent, and use dispersion agent to process rubber powder, can prevent rubber powder from condensing in butyronitrile latex solution, reach good dissemination.Therefore use present method common butyronitrile latex not only can be used to substitute adhesive special, greatly reduce production cost, but also can products quality guarantee and product design attractive in appearance.
