Abstract
The invention relates to a macromolecular coating manufacturing technique of a medical rubber glove. The manufacturing steps are as follows: cleaning of moulds, coagulator dipping of a glove mould, rubber latex dipping of the glove mould, hemming of the rubber latex, former leaching, after leaching, demoulding with clear water, water vulcanization and stirring of macromolecular solution; after drying, altex gloves are obtained. The novel macromolecular coating technique is used for manufacturing the medical rubber glove with no powder, which shortens the production period of the product, reduces the energy consumption and enhance the performance of the product; in addition, as the two technical processes of the breading and the surface chloridization are omitted, the environmental pollution is improved, and the economic and social benefits are very good.
Description
One, technical field
The invention belongs to the gloves technical field, particularly a kind of production technology of polymers coatings robber gloves for medical use.
Two, background technology
Prior art: existing rubber medical glove is that the employing Heveatex is a raw material, adopts Anode method dipping to form, and mainly protects articles for use as medical grade rubbers such as medical examination and operations, and being divided into has two kinds in powder and no powder.The product of producing exists chemical residue and protein to have skin irritation because technology falls behind in (process chart one) product at present, defectives such as anaphylaxis and external severe toxic cell, owing to use in the production technology and help that to wear powder and powder production will be arranged be to adopt the surface chlorination treatment process to cause the serious environmental pollution and wasted a large amount of energy and labour for no powder, because protein allergy caused the allergic of medical worker, serious generation death.Western developed country begins to ban the rubber medical glove that uses Heveatex to produce gradually.
Three, summary of the invention
Technical problem: technical problem to be solved by this invention is: at above-mentioned technical problem, provide a kind of production technology of polymers coatings robber gloves for medical use.Need not breading, surface chlorination in this production process and handle, the rubber gloves chemical residue content that obtains of producing low, and little to the human body skin excitant.
Technical scheme: technical solution of the present invention is: a kind of production technology of polymers coatings robber gloves for medical use, production stage is: mould cleans: with hydrochloric acid glove mould was carried out dip pickling 10-15 seconds, 80-90 ℃ hot water injection is then used in the clear water flushing at ambient temperature of glove mould after the pickling again; Glove mould coagulating agent dipping: mould is impregnated into 55-65 ℃ coagulating agent after cleaning, and glove mould is in 1-2 minutes time of coagulating agent dipping; After glove mould was finished the coagulating agent dipping, drying was 3-5 minutes under 120 ± 5 ℃ of conditions; The glove mould latex dipping: on go on foot dried glove mould and be impregnated into latex, the latex temperature is 40-50 ℃, dip time is 1-2 minutes; After glove mould was finished latex dipping, drying was 3-5 minutes under 110-120 ℃ of conditions; The latex crimping: glove mould divides latex to carry out crimping by hemming device to glove mould left-hand seat wrist after finishing the step drying, and the crimping time is 8-10 seconds; Preceding leaching: the glove mould behind the crimping soaked 60-90 seconds in 55-60 ℃ water; Glove mould after the leaching under 110-120 ℃ of conditions dry 10-15 minutes; Back leaching: the glove mould after drying is finished soaked 60-90 seconds in 90-95 ℃ water; The clear water demoulding: the water with cleaning washes the demoulding to the emgloves on the glove mould; Water cure: the emgloves that the demoulding is got off is put into tank diameter and was steeped 50-60 minutes with 95-100 ℃ hydro-thermal; Mix Polymer Solution: through the emgloves behind the water cure stirs 10-15 minutes in calcium stearate solution after, take out oven dry, get the emgloves product.The mass concentration of calcium stearate is 5% in the calcium stearate solution.Coagulating agent is that the aqueous solution configuration of calcium nitrate and calcium stearate forms, and wherein the mass concentration of calcium nitrate is 4%-6%, and the mass concentration of calcium stearate is 5%-6%.In the latex latex total solid mass concentration be between 30% ± 2.
Beneficial effect: the non-powder rubber medical glove that adopts this polymeric coating layer new technology to produce has shortened life cycle of the product, reduced energy consumption, properties of product have been improved, in addition, owing to removed breading and surface chlorination is handled this two technical process, environmental pollution is improved, and has obtained good economic interests and social benefit.The gloves of producing are smooth smooth.The old and new's technology has different production requirements in whole process of production.Old production technology is that powder production is arranged on train line, does not take leaching technology, and the product that takes off contains protein, and exists a large amount of helping to wear powder need to carry out repeatedly water treatment, removes powder and carries out surperficial chlorine again and handle.And new production technology is to increase leaching plant on the train line, uses the clean water demoulding, and whole process does not contain powder, and the product that takes off adds Polymer Solution back the no powder of oven dry promptly becoming that stirs after by water cure and hangs down the albumen medical rubber glove.Its advantage is: 1. there is not powder, and smooth, not sticking, low irritated, no protein.2. artificial energy source's saving is the contrast of related process parameter: Fig. 1 below, 1, the old technology human and material resources that have the powder product to need post processing to exhaust, the semi-finished product bubble is washed, 3500 pairs in every material, semi-finished product per hour consume 1.5 tons in running water (100 ℃ of hot water), need 0.5 ton in consumption coal, then carry out semi-finished product breading 30 minutes again, carry out heat again and shake dry the processing, 1.5-2 hours consuming time, more than per ten thousand pairs of products need expend 1 ton in energy coal, 4-5 tons in water, one when artificial.2. old technology does not have the human and material resources that the powder product needs post processing to exhaust: the semi-finished product bubble is washed (3500 pairs in every material, semi-finished product per hour consume 1.5 tons in running water, coal-fired 0.5 ton), then carry out surface chlorination and handle, 10-15 minutes, product pulled out carry out clear water and filtered 45 minutes, carry out heat again and shake drying, and the sewage that surface chlorination is handled carries out in the buck again and after discharge, and such carry out labor intensive 2 people repeatedly, and per ten thousand pairs of the water resources of waste are at 5-6 tons.Figure two: the polymeric coating layer that new technology is produced does not have the powder product.
