The preparation method of the environment-friendly superhydrophobic cutting-proof fabric glove coating comprises the following steps: under a normal pressure condition, adding 30 to 45 mass percent of polyurethane and 4.5 to 6.1% mass percent of polybutadiene resin into a rubber tank containing 45 to 55 mass percent of solvent; and adding 0.3 to 0.7 mass percent of initiating agent lithium alkylide; raising the temperature to 50 to 60 DEG C and stirring for 1 hour; after uniformizing the solution, adding to 1 to 3 mass percent of defoaming agent and 1 to 3 mass percent of penetrant, and further stirring for 2 hours; and finally, adding 1.2 to 4.2 mass percent of fluorine silicon coupling agent, and stirring for 30 minutes to obtain the superhydrophobic glove coating. The coating prepared by the reparation method and a glove produced by a method for producing the glove are good in elasticity, low in toxicity, high in hydrophobicity and good in cutting-proof performance.
Description
Technical field
The invention belongs to a kind of preparation method of fabric glove surface functional coating, specifically a kind of environmentally friendly super-hydrophobic anti-cutting fabric glove coating preparation method.
Background technology
In process of production, finger is the highest position of human body injury rate, if work accident is classified according to injury according to the relevent statistics, in all kinds of work accidents, hand injury accident accounts for more than 20%.With respect to western developed country, China also has many fields also there is no advanced production unit, and handwork is still playing a part the weight of stopping, and often occurs the injured accident of serious hand.Can not get under the present situation of raising at production sublimity and technology, use reasonable hand protection articles for use, particularly protective gloves just to become the important supplementary means of prevention hand injury.
Some function gloves, except protection finger is not subject to injury that external force is larger, also play good electrostatic-proof function at electronic applications, avoid the infringement of workman's self-electrostatic to electron device.Current, nearly all work gloves is all cotton or synthon sewn glove lining, then covers with paint, lacquer, colour wash, etc. in the above various latexes, and polymer emulsion etc., to meet for different production fields such as agricultural, fishery, chemical industry, electronics.Although this gloves are poorer than emgloves feel, de-wearing easily, easy to use.In addition, woven lining has good reinforcement effect, better anti-cutting, cut, the effect such as pierce through, totally present stronger working strength.
China is the big producing country of gloves, has every year a large amount of products exports to countries in the world, strong promotion the high speed development of this industry, for vigor has been injected in the development of gross national product and local industries.But along with the increase of people's environmental consciousness, external but more and more higher to the nontoxic of glove coating or low toxicity standard, the current noxious solvent (as DMF) generally using has stopped up the discovery road of this series products to a certain extent.In addition, PU type coating elasticity and water resistance that current industrial is used are poor, and use field is narrower.Therefore, develop multi-functional nontoxic gloves coating material and become the common recognition of the sector.

Embodiment tri-
The polybutadiene that is 6.1% by the urethane of total mass number 45% and total mass number under condition of normal pressure, adding and containing total mass number is in 45% the glue groove of N,N-DIMETHYLACETAMIDE (DMAC) solvent, and to add total mass number be 0.7% initiator lithium alkylide, be warmed up to 50-60 degree and stir 1 hour, after solution is even, adding total mass number is 1% defoamer and 1% permeate agent, continues to stir 2 hours, finally adding total mass number is 1.2% fluorine silicone couplet, stirs and can obtain super-hydrophobic glove coating in 30 minutes.
A kind of making method of environmentally friendly super-hydrophobic anti-cutting fabric gloves is as follows:
1, with in-line pump, the deployed hydrophobic glove coating of above-mentioned height is transported to cement dipping machine, then is transported to the glue groove of machine with in-line pump;
2, the knitting gloves core check mark cover completing is started with and touched;
3, gloves with fingerprint to filling impregnation in the groove of PU glue.Being transported to certain position with the conveyor belt of fingerprint suspends, then the groove meeting automatic-ascending of glue is housed to certain altitude, gloves will immerse in glue, glue are layed onto to the certain position of gloves, suspend for some time pit and decline, the row's fingerprint that has soaked glue is transported to next process;
4, tentatively solidify 5-8 minute.Glove fingertip, is transported (relative humidity between 30-35%, temperature degree in summers 30-40, be 60-70 degree winter) taking certain constant speed down in the passage of constant temperature humidity;
5, further solidify, reduce objectionable impurities contained in coating simultaneously.Gloves are continuously through four water tanks, the working temperature of each water tank and water-bath time respectively: the time 7-8 minute of first normal temperature water tank: the second water tank temperature is 40-50 degree, the water-bath time is 8-9 minute; The 3rd water tank 60-65 degree, water-bath time 10-12 minute; The 4th water tank temperature is 70-72 degree, water-bath time 10-12 minute.
6, the gloves of water-bath pass through oven for drying again, and temperature is that between 70-80 degree, baking time is 1-1.5 hour;
7, gloves drop to normal temperature through longer path temperature, turn back to zero position and are taken off by workman, again load onto gloves and start a new round and return.
In fact overlap gloves and to unload gloves be to carry out continuously, because this streamline is as the chain on tank wheel, separated by a distance just have row's fingerprint, ceaselessly rotating with constant speed.
These environmentally friendly super-hydrophobic anti-cutting fabric gloves have good permeability, good springiness, and low toxicity, thermal resistance and acid-alkali resistance, hydrophobic and anti-grease, anti-hook is broken, the advantages such as odorlessness and skin contact not damaged.Weaving gloves are by invading bubble, smooth and level, solidify the functional modification that waits coating processes can realize gloves.Apply the hydrophobic effect of gloves after this figure layer as shown in Figure 1, the contact angle of water can reach 155 degree, meets the requirement of ultra-hydrophobicity completely.
Shown in the above and figure is only the preferred embodiment of the present invention.It should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
