Abstract
The invention discloses a preparation method for a rubber glove, which is prepared from a latex composition. The latex composition comprises, by weight part, 50-70 of polybutadiene latex, 20-40 of butylbenzene latex, 3-8 of 2, 2-dithienyl methyl glycolate, 4-8 of N-cyclohexyl-2-benzothiazole sulfenamide, 1-5 of zinc oxide, and 1-5 of an antioxidant D. Through a specific rubber formula and preparation technology, the method provided by the invention effectively improves the acid and alkali resistant properties of the rubber glove.
Description
Technical field
The present invention relates to a kind of safety and industrial gloves and preparation method thereof, relate in particular to a kind of rubber gloves and preparation method thereof, be specifically related to a kind of rubber gloves and preparation method thereof.
Background technology
In existing appliances for labor protection, safety and industrial gloves is an important equipment.
Old safety and industrial gloves, majority is leather, for example, by pigskin or ox-hide, made, this class gloves material is harder, is unfavorable for the bending that laborer points, and ask for something is pointed place application flexibly.
Along with the development of the tremendous development of manufacturing process and material, particularly rubber and matrix material, increasing new variety have been there are.According to the material of gloves, safety and industrial gloves can be divided into the safety and industrial gloves of rubber, safety and industrial gloves, the safety and industrial gloves of leather quality and the safety and industrial gloves of knitted yarn of steel wire (steel loop).Rubber gloves is because its protection against corrosion, insulation, waterproof are mainly used in electrician, in the operation process such as keep a public place clean; Steel wire gloves is because it is effectively in the anti-stab process that is mainly used in the operations such as food-processing, packing, cutting of anti-cutting; Leather gloves is because it can wear-resisting, anti-scaldly be generally used in the process of the operations such as light industry, handling; The safety and industrial gloves of knitting class is also modal a kind of, be mainly used in environmental sanitation, building etc. industry.
In present safety and industrial gloves, rubber safety and industrial gloves occupies critical role.
CN1552759A discloses a kind of acrylonitrile butadiene glove of upgrading, it is that intensifier is added into the gloves that make in the latex mixture of paracril, its thickness is between 0.120-0.150mm, its tensile strength is between 18-30MPa, and the relaxed stress after 6 minutes is lower than 50% of its former stress.Intensifier is to be selected from carboxymethyl cellulose, and it adds weight is 2% of paracril.There is the antiwear characteristic that improves gloves and the effect of dressing comfortableness.
CN1631645A discloses a kind of manufacture method of butadiene acrylonitrile rubber medical gloves, comprise the following steps: A. sizing material is prepared: mix two kinds of paracril latex, mixed volume ratio is 30: 70～70: 30, and in two kinds of paracril latex, the content of vinyl cyanide differs 3%～10%; B. sizing material is carried out to prevulcanized, the proportioning of prevulcanized agent is: 1～5% KOH, 0.5～2.0% sulphur, 0.6～3.0% ZnO, 0～1.5% ZDC, 0～1.0% BZ, 0.6～2.5% titanium dioxide; C. moulding; D. sulfuration; E. surface treatment.By employing mixing nitrile rubber, as raw material, by adjusting material rate, having improved design parameter and the technological process in production process, make the butyronitrile medical rubber glove pliability produced good, stress at definite elongation is low, and tensile strength at yield is good.
But the preparation-obtained rubber gloves of prior art, because matrix is latex, so its performance is limited to the performance of matrix, often can not meet the use of specific occasion.
Summary of the invention
The object of the present invention is to provide a kind of formula of rubber gloves, described rubber gloves is mainly used under acid or alkali environment, therefore requires the acid-proof alkaline of described rubber gloves to get well.
For reaching this object, the present invention by the following technical solutions:
A rubber gloves, described rubber gloves is prepared from by latex composition, and described latex composition comprises by weight:
The preparation technology of rubber gloves of the present invention, described preparation method comprises the steps:
(1) plasticate: according to described weight fraction, polyhutadiene latex and butadiene-styrene latex mixing are plasticated;
(2) mixing: the rubber after plasticating is dropped into thermoplastic 3-12min in Banbury mixer, then add successively 2,2-dithienyl methyl glycolate, N cyclohexyl 2 benzothiazole sulfenamide, zinc oxide, antioxidant D carries out mixing, mixing evenly rear binder removal, dump temperature is 90-120 ℃, finally slice in mill;
(3) refining: first the rubber that step (2) obtains cut into slices through rubber mixing machine, after section, send colloidal sol cylinder and gasoline mixed sols, colloidal sol again through emulsification, modulation after by pumping latex tundish, the rubber solutions that is dissolved in gasoline is sent into from the top of distillation tower, through steam heating, distill, light constituent gasoline is heated into gas phase, gasoline gas is also cooling by cold water mix at oil gas water cooler, oil-water mixture is again to water-and-oil separator, profit layering, upper strata gasoline recovery, it is cooling that bottom water is delivered to water cooling tower through water pump again, cooling after the natural gas liquid of cooling distillation tower again; Distillation tower reactor latex send that latex a mixing bowl stirs, isolates glove material latex to whizzer after modulation according to self pressure, more stand-by through toning, after filtering;
(4) moulding: glove model first, water clean through soda acid cleans, clean model first immerses after hot water heating to soaking peptizer and dryly carrying out impregnation, send baking oven tentatively to dry, add fiber inner sleeve, rushes hot water and deliver to baking oven sulfuration, drying forming again after impregnation; And optionally carry out:
(5) after gloves demolding, inflation checks, obtains qualified rubber gloves after low-temperature shaped, middle temperature is dried, washing, dehydration, oven dry.
The present invention, by specific rubber compounding, has effectively improved the acid-proof alkaline of rubber gloves.
