Description
Technical field
The present invention relates to the butyronitrile latex film-forming process in oil-resistant glove field, especially a kind of non coagulant method butyronitrile latex film-forming process on cotton courage.
Background technology
Ca (NO
3)
2, CaCl
2the advantage that methyl alcohol coagulating agent method soon, is not easily permeated owing to having film forming, become the important method that butyronitrile latex produces oil-resistant glove, although the method uses extensively, but in use there is a lot of defect equally in it: as poor in the NBR film-strength after shaping, not wear-resisting, surface brightness is poor, process needs the operations such as washing, dehydration and drying, and therefore existing this methyl alcohol coagulating agent method all causes very large harmful effect to the quality of oil-resistant glove and whole production process.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of non coagulant method butyronitrile latex film-forming process on cotton courage that can improve shaping rear NBR film-strength and wearability, improve film surface brightness, ensure end product quality.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of non coagulant method butyronitrile latex film-forming process on cotton courage, is characterized in that: comprise the following steps:
(1) adopt thickener that the viscosity of butyronitrile latex solution is adjusted to 200-300cp;
(2) temperature of production control line mold self is 65-80 DEG C;
(3) mould being set with cotton courage enters into butyronitrile latex solution according to 20rpm-30rpm rotary speed and certain angle, and butyronitrile latex makes cotton courage surface form uniform liquid film;
(4) mould after step (3) process leaves dipping tank, after allowing mould downward three minutes pouring drops fall the butyronitrile latex solution of cotton courage excess surface, mould is first allowed to rotate while natural drying, and then the mould being set with cotton courage put into the baking oven of 50-70 DEG C, about about 15 minutes, make it the solidification of overall film forming;
(5) rotate the cotton courage after overall film forming in step (4) while be impregnated in the butyronitrile latex solution of non-thickening, the concentration of its latex solution is regulated by water, controls the weight demands of product glued membrane;
(6) leave in the butyronitrile latex solution of the mould making to be set with cotton courage never thickening, downward three minutes of mould drench drop fall cotton courage excess surface butyronitrile latex solution and after natural drying, put into baking oven again and make it solidification, baking temperature is increased to 110 DEG C gradually by 90 DEG C and makes glued membrane sulfuration, until whole curing molding.
And the thickener described in step (1) is Sodium Polyacrylate.
And the mould described in step (3) becomes 20-40 ° of angle to enter with butyronitrile latex solution.
And the feature that the part that the cotton courage described in step (3) is not impregnated into utilizes mould to rotate, waters with artificial or automated manner and drenches butyronitrile latex liquid about 3 seconds.
And, add sulphur body in the butyronitrile latex solution of the non-thickening described in step (5).
And the mould of the cotton courage of described suit is in rotation status in whole technical process always.
Advantage of the present invention and beneficial effect are:
1, adopt sodium polyacrylate thickener that latax viscosity is adjusted to 200-300cp in this film-forming process, this modest viscosity, and the thickener dosage added is limited, ensure that the quality of forming film of butyronitrile latex, strike-through phenomenon can be avoided, strengthen oil resistivity and the water proofing property of gloves.
2, in this film-forming process, the temperature of mould self is 65-80 DEG C, utilizes the characteristic of NBR thermosetting film forming, prevents the generation of strike-through phenomenon further.
3, in this film-forming process, mould becomes 20-40 ° of angle to enter with butyronitrile latex solution, mould enters and leaves in the process of butyronitrile latex solution and constantly rotates, shorten the cotton courage time of staying in the solution as much as possible, therefore can reduce the strike-through caused by the pressure of solution depths, improve the uniformity of butyronitrile glued membrane.
4, the mould being set with cotton courage in this film-forming process drenches after drop falls unnecessary butyronitrile latex solution, first rotate while natural drying solidification, and then the overall film forming solidification of the baking oven putting into uniform temperature, this technique eliminates washing and drying step, simplifies technological process, improves working (machining) efficiency and product quality.
5, this production technology does not need to use chemicals, as methyl alcohol, CaCl
2deng, nor need to use water, therefore whole production process is not only environment friendly and pollution-free, but also reduces energy consumption.
6, the present invention is a kind of reasonable in design, technique is simple, production efficiency is high non coagulant method butyronitrile latex film-forming process on cotton courage, NBR film-strength after adopting this processes shaping is high, wear-resisting and oil resistivity is good, surface smoothness is high, is the non coagulant method of current and that future is important cleaner production.
