Description

A kind of gloves and preparation method thereof
Technical field
The present invention relates to gloves manufacture field, in particular to a kind of gloves and preparation method thereof.
Background technology
Present people more and more focus on quality of the life, every aspect in cooking in life, have dinner and living all can use disposable glove, disposable glove great majority on the market adopt polyethylene film hot pressing, polyvinyl chloride material, latex material or nitrile rubber material dip forming to be made, but the disposable glove that these materials make cannot be degraded after being finished and abandoning or is difficult to degraded, environmental pollution is very large, not environmental protection.
Summary of the invention
The object of the present invention is to provide a kind of gloves and preparation method thereof, to solve the above problems.
Provide a kind of gloves in an embodiment of the present invention, its starting material comprise following component according to the mass fraction: PVA resin 90-120 part, softening agent 8-12 part, defoamer 0.5-1 part, softening agent 2-5 part, releasing agent 0.5-2 part, lubricant 0.5-1 part.
The gloves that the embodiment of the present invention provides, compared with gloves of the prior art, it adopts PVA resin material to be raw material, and these gloves, after use, are dissolvable in water in high-temperature water, under normal temperature state in dissolved water, can not meet and substantially dress requirement.After being dissolved in the water, solid waste is changed into liquid waste, water supply company's sewage disposal pipe network can be entered by waste pipe, greatly reduce processing cost, also by land-fill method process, degrade at physical environment, final degradation production is carbonic acid gas and water, environmentally safe, environmental protection.
Preferably, its starting material comprise following component according to the mass fraction: PVA resin 90-100 part, softening agent 8-10 part, defoamer 0.5-0.8 part, softening agent 2-3 part, releasing agent 0.5-1 part, lubricant 0.5-1 part.
Preferably, described softening agent is one or both in the pungent different ester of dioctyl phthalate (DOP) and phthalic acid two, to weaken molecular force between raw material, strengthens the plasticity-of product, can also reduce the temperature in the course of processing.
Preferably, described lubricant is one or both in paraffin, nano level talcum powder, to reduce the mutual rubbing effect between raw material, reduces wear.
Embodiments provide a kind of preparation method of gloves, comprise the steps:
(A) PVA resin and mix lubricant are stirred until after being warmed up to 80-90 DEG C, after softening agent, defoamer, softening agent and releasing agent are added mix and blend 10-15min, stop stirring obtaining powder;
(B) by described powder and soft water in mass ratio 1:10-12 carry out mix and blend, warming while stirring to 50-70 DEG C of low whipping speed is that under the condition of 400-500rad/min, mix and blend 10-20min obtains powder solution;
(C) filter after described powder solution being cooled to 30-40 DEG C, preserve under vacuum conditions;
(D) hand-type after cleaning-drying is immersed in described powder, then through dripping filter, drying, cooling and after flange, gloves are peeled off from described hand-type and be get final product.
The preparation method of a kind of gloves that the embodiment of the present invention provides, compared with the preparation method of gloves of the prior art, starting material temperature and stirring velocity when mixing all have the scope of restriction, temperature will be suitable for the moderate starting material that make of stirring velocity and mix, there will not be caking or the deeply worried phenomenon of the too fast powder of the too high stirring velocity of temperature, especially the powder prepared needs to allocate with soft water, not containing sodium in soft water, magnesium ion, preserve under vacuum after filtration, prevent the foreign material in hetero-ion and air from interfering with the state of powder, affect the quality of the gloves prepared.
Preferably, in described step (D), described hand-type through the concrete steps of cleaning-drying is: be first soak 10-20min in the water of 50-60 DEG C to scrub and spray and clean in temperature by described hand-type, then at temperature is 150-160 DEG C, 3-4min is dried, finally under temperature is the condition of 10-20 DEG C, be cooled to 60-70 DEG C, hand-type is the key making gloves, therefore it will keep certain degree of cleaning, soaks, cleans, dries and cools a whole set of technical process and carry out pre-treatment to hand-type.
Preferably, the concrete steps that the hand-type that impregnated of described powder in described step (D) carries out dripping filter are: under temperature is 150-160 DEG C of condition, drip filter 3-4min, the powder dripped under filter reclaims, hand-type after impregnated of powder has a small amount of powder drippage, by its recycling use, not only save starting material but also environmental protection.
Preferably, through dripping the hand-type after filter through twice oven dry, twice cooling in described step (D), it is better that oven dry and cooling are preferably the gloves forming degree hocketing for twice to make to produce.
Preferably, in described step (D) through dripping the hand-type after filter through the concrete steps of twice oven dry, twice cooling be: described hand-type first dries 5-10min under temperature is 120-130 DEG C of condition, then be carry out flange after being cooled to 60-70 DEG C under the condition of 10-20 DEG C in temperature, after finally repeating first drying, cooling step again, be cooled to 30-40 DEG C.
