Description
Technical field
The present invention relates to a kind of rain boots, especially a kind of production technology of the rain boots of waterproof and breathable.
Background technology
Rain boots, it is the shoes in rainy day dress in traditional sense.Short Yao, middle Yao and high Yao are divided into according to the height of footwear cylinder.
What ordinary people often wore be in, short Yao rain boots, its high highest also just reaches ankle above 10cm or so, and some special work posts
Occupational staff needs cylinder to be up to the high Yao rain boots to knee position as appliances for labor protection, due to high Yao rain boots waterproof, insulation blocking
Demand, its permeability is often poor, dress it is extremely uncomfortable.
Generally, corium has good waterproof and breathable performance, but is restricted by its yield, price and people are to leather demand
Increasingly increase, exploitation is ventilative, synthetic leather product both with water resistance turns into the skill that those skilled in the art need to solve
Art problem.
Waterproof and it is ventilative be always a pair of conflicting indexs, it is impossible to utterly propose that water proofing property is fabulous and gas permeability
Excellent rigors, according to people in recent years to objectively understanding, measure in the case of being engaged in vairious activities, material is due
Venting capability.The due gas permeability of people's material in various activities, root is it was found that an it has been proposed that venting capability minimum
2500g/m224h concept, American researcher is from hydrodynamics viewpoint, it is believed that minimum anti-quiet as waterproof material
Hydraulic pressure value should be not less than 1.76kg/cm2, have reference index, be easy for the performance of more all kinds of permeable waterproof materials.
The content of the invention
It is an object of the invention to provide one kind to take into account waterproof, the production technology of ventilative rain boots, is ensuring rain boots use
Comfortable dress is provided while effect to require.
To achieve these goals, the present invention is achieved using following technical scheme：A kind of rain boots of waterproof and breathable
Production technology, including shoe body and sole are made respectively, then compression molding is connected as a single entity, and specifically includes following steps：
(1) preparation of shoe body：
The polyurethane resin containing titanium dioxide is added into nitrile rubber, reinforcing agent and auxiliary material, is well mixed, passes through refining glue
Machine is kneaded, and collosol intermixture is pulled, tentatively compressing to collosol intermixture to obtain shoe body；
(2) preparation of sole：
(2.1) nitrile rubber, butadiene rubber, natural rubber, RX, vulcanizing activator and carbon black filler are added
Enter into banbury banburying 5-10min, obtain pre-composition；
(2.2) above-mentioned pre-composition and vulcanization accelerator are put into and 3-5min are refined in rubber mixing machine, then add foaming agent,
Continue to refine 0.5-1min, discharge to flat machine, supplement is turned refining uniform elastomeric compound, and elastomeric compound scribing is cooled down to obtain mixture；
(2.3) by above-mentioned mixture carry out two sections of refining glue methods, repetition refine it is soft uniformly after, cut into sole sizing material embryo piece；
(3) shoe body is connected with sole：
Gluing shoe bottom, foxing under the help foot for the last carving that tacks down, sole sizing material embryo piece is put into mould, is heated and is added
Pressure, through sulfidization molding, rain boots finished product is made.
Then rain boots of the present invention are connected as a single entity, in this way, can using sole and shoe body is made respectively in compression molding
Respective demand is adapted to be separately designed to sole and shoe body, described sole needs have enough hardness and intensity, and
Described shoe body needs to take into account ventilative and waterproof performance.
In the present invention, by nitrile rubber and the polyurethane resin blending and modifying incompatible with described nitrile rubber,
During being pulled to collosol intermixture, by the two shows different stretching, extension trend, in nitrile rubber and poly- ammonia
The interface that ester resin is in contact forms micropore gap, and nitrile rubber passes through with the ranks flake structure that polyurethane resin is formed
Shaped after heat treatment, these 0.2-10 μm of micropore gap diameters, because the diameter in micropore gap is the 1/ of drop diameter
5000-1/20000, it is 700 times of water vapour molecule diameter or so, therefore water droplet can be prevented by and allowing water vapour molecule
Pass freely through.Waterproof and ventilative effect are taken into account in this way, can realize.In order to realize stretching for nitrile rubber and polyurethane resin
Exhibition, by differential speed roll stretch collosol intermixture, extensibility 1.2-2.5, extensibility is too small, then is not easy to form foot
Enough big micropore gaps, and extensibility is excessive, easily causes to be pulled open.
In the present invention, titanium dioxide, the mistake that titanium dioxide stretches in collosol intermixture are also filled with described polyurethane resin
Also the foam structure using it as core is formed in journey, to ensure dispersed in the polymer, the described titanium white of described titanium dioxide
Powder is through coated with polyethylene glycol modification, and further, the particle diameter of described titanium dioxide is 0.1-0.4 μm, the particle diameter of titanium dioxide
It is too small, then it is not easy to form suitable foam structure, and particle diameter is excessive, then is easily caused collosol intermixture and is ruptured in drawing process.
According to the present invention, in heretofore described step (2.2), the temperature of rubber mixing machine is 90-110 DEG C, and pressure is
0.35-0.40Mpa。
According to the present invention, in heretofore described step (2.3), the temperature of two sections of refining glue methods is 40-60 DEG C.
According to the present invention, in step (3), in order to ensure shoe body with sole fusion connection together with, simultaneously, it is ensured that described
Shoe body and sole vulcanization, the rain boots of assembling are put into vulcanizing treatment in vulcanizing tank, curing temperature is 150-155 DEG C, pressure
For 0.30-0.40Mpa.
According to the present invention, described reinforcing agent is that the rubber that is used to improve commonly used in modified rubber process improves intensity
Additive, the present invention do not do particular/special requirement to the species of described reinforcing agent, can often know for one of ordinary skill in the art
, one or more of mixtures in white cigarette, black smoke, kaolin.
Described auxiliary material is some additives conventional during rubber processing, and the present invention is not repeated this.
According to the present invention, described RX is by dibutyl phthalate, rubber softening oil and pine tar mixture
Form.
According to the present invention, described vulcanizing activator is nano zine oxide and stearic acid by weight 1：(0.1-0.3) is mixed
With into.
According to the present invention, described vulcanization accelerator is N cyclohexyl 2 benzothiazole sulfenamide, the N- tert-butyl groups -2-
Benzothiazole sulfenamide, 2,2 '-dibenzothiazyl disulfide, tetramethylthiuram monosulfide, 2- thiol benzothiazoles, two
Vulcanize tetra methylthiuram one of which or two or more compositions.
Heretofore described shoe body includes the material composition of following parts by weight：Nitrile rubber 30-42 parts, reinforcing agent 0.1-
1 part, polyurethane resin 1-8 parts, titanium dioxide 0.01-0.05 parts.
Described sole includes the material composition of following parts by weight：Nitrile rubber 20-32 parts, butadiene rubber 10-15 parts, day
T PNR 3-10 parts, RX 0.1-0.5 parts, vulcanizing activator 0.02-0.1 parts, carbon black filler 0.01-0.5 parts, sulphur
Change accelerator 0.1-0.5 parts.
The present invention technique effect be：
1st, using the production technology of rubber overshoes provided by the invention, shoe body and sole are manufactured respectively, it is real respectively
Existing different and corresponding function, is then combined together by way of compression molding again, simple and convenient；
2nd, the rain boots that the present invention prepares have taken into account the performance of waterproof and breathable, it is ensured that more comfortable when dress.
