Abstract
Carboxy butyronitrile latex oil-resistant glove of the present invention and preparation method thereof belongs to industrial latex product field.It is to be that primary raw material and the cooperation of other auxiliary agents form with the carboxylic acrylonitrile butadiene rubber latex that the raw material of this oil-resistant glove is formed.The present invention formula for raw stock is adjusted with improved basis on, mend in dipping, dry, poach fluidisation and back again and improving aspect the production technology such as sulfuration, produce that quality softness, wearing are comfortable, oil resistant, well behaved oil-resistant glove such as wear-resisting.These gloves are widely used in having very big social benefit and economic benefit in the labour protection of industrial departments such as modern petrochemical industry, oil field oil refining, mining machinery, grease processing and aquatic products processing.
Description
Carboxy butyronitrile latex oil-resistant glove of the present invention and preparation method thereof belongs to the field of industrial latex product.
Industrial employed oil-resistant glove has several types such as rubber oil-resistant glove, plastics oil-resistant glove and latex oil-resistant glove at present.Wherein other hand, very inconvenient is hardened, dressed to straight, the quality of the hand shape plate of rubber oil-resistant glove; The plastics oil-resistant glove has the weakness of plastic products: winter is hard and crisp, summer is soft, easy aging, life-span weak point, and price is higher; The quality softness of emgloves, dress comfortable, particularly carboxy butyronitrile latex oil-resistant glove has more good oil resistivity, resistance to acids and bases, wearability and paracentesis resistance than Heveatex gloves and polychloroprene latex gloves, be in a kind of modern industry quality better, the oil-resistant glove product liked of the personnel of being manipulated deeply.But the primary raw material of producing carboxy butyronitrile latex oil-resistant glove is a carboxylic acrylonitrile butadiene rubber latex.Output is little in the world at present for this latex raw material, costs an arm and a leg, and can't satisfy industrial demand.And the oil-resistant glove that utilizes homemade carboxylic acrylonitrile butadiene rubber latex to be made into as raw material is because the raw material grade is different with quality, production technology does not match, so low, the poor-performing of the product percent of pass of producing can't put into production in batches, is difficult to satisfy the needs on the industrial production.
The objective of the invention is to avoid above-mentioned weak point of the prior art, existing factory formula and process conditions are improved, utilize homemade carboxylic acrylonitrile butadiene rubber latex to be primary raw material, it is functional to produce a kind of oil resistant etc., steady quality, the carboxy butyronitrile latex oil-resistant glove that qualification rate is high is to satisfy the demand of special operation such as oil resistant in the industrial production.
Main points of the present invention are that it is to be primary raw material with homemade carboxylic acrylonitrile butadiene rubber latex that the raw material of this carboxy butyronitrile latex oil-resistant glove is formed, and in addition auxiliary agent cooperates and forms.It forms content is (weight portion):
Carboxylic acrylonitrile butadiene rubber latex 100.00
Ammonia casein 0.1-0.4
Sofril 1.5-2.5
Promoter ZDC 1.0-2.0
Antioxidant D 0.5-2.0
Curing agent H 1.0-2.0
Dibutyl phthalate (DBP) 0.5-2.0
Colouring agent 1.0-10.0
Zinc oxide 1.0-6.0
Phenolic resins 5.0-15.0
Diffusion agent N F 0.1-0.6
Water is an amount of
In the prescription of oil-resistant glove of the present invention is formed, adopted with phenolic resins as reinforcing agent, replaced normally used polyvinyl chloride (PVC) reinforcing agent, thereby solved the problem of NBR latex film forming difference, prevent the cracking of product, increased hot strength.Secondly, adopted hexamethylenetetramine or Urotropinum, the shrinkproof water-based of product can have been improved greatly, thereby reach the product specification standardization as curing agent.In the present invention, the consisting of of ammonia casein (weight portion): casein 1, ammoniacal liquor 2, distilled water 7.Phenolic resins can be 2133 phenolic resins (productions of Tianjin auxiliary agent one factory).
Simultaneously, the alcohol coagulating agent that the woven lining gloves are adopted, the starch, peach gum, glycerine that have replaced original use are as coagulating agent, and its composition is (weight portion):
Calcium chloride 5.0
Alcohol 95.0
This coagulating agent has solved strike-through seep through phenomenon, has improved product quality.Aspect product structure, improved, attachedly do the lining skeleton with yarn fabric, increased the intensity and the toughness of product, improved shrinkage factor, it is comfortable, sturdy and durable that these gloves are dressed more.
In the present invention, promoter ZDC, antioxidant D, curing agent H, diffusion agent N F all are that the latex industry is used always, can buy from auxiliary reagent factory, Shanghai or auxiliary reagent factory, Beijing etc., sofril, zinc oxide can be buied from market, and carboxylic acrylonitrile butadiene rubber latex can be buied from Shanghai rubber plant.
In the present invention, water preferably uses distilled water or deionized water as a kind of diluent, and its amount is generally an amount of, that is, make in the prescription composition viscosity suitable, makes it to be fit to subsequent operation, is generally 0.5-4 part (based on composition).Coating and dyestuff be the industry commonly used as rubber red, orange, blue, green etc.
The manufacture craft process and the routine techniques of carboxy butyronitrile latex oil-resistant glove of the present invention are similar substantially, operation is basic identical, comprises that mainly batching, dipping (impregnation breast and soak coagulating agent), typing, leaching, semi-finished product drying, the demoulding, poach fluidisation and back mend operations such as sulfuration.In order to use homemade carboxylic acrylonitrile butadiene rubber latex to produce qualified oil-resistant glove,, production technology and condition have also been done corresponding improvement adjusting and improving on the basis of composition of raw materials.Mainly contain: when the dipping coagulating agent is handled glove liner, change into lining is immersed in the coagulating agent, drying dehydration is compared labor and material saving with former dipping method then.When semi-finished product were dry, baking temperature and drying time by 70 ℃-80 ℃ of the past, 40-45 minute, changed 95 ℃-105 ℃ into, 55-65 minute respectively.In poach fluidisation operation, need the time long (about 90 minutes) in the past, thereby easily delamination, get blister, of poor quality.Now will shorten to 20-30 minute the operating time, not only save man-hour greatly like this, improve qualification rate, also play the effect of antimycotic antiseptic simultaneously.Mend in the vulcanisation operation in the back, no longer adopt and shake baking, but directly place baking indoor under 115-125 ℃ of temperature, dried 55-65 minute, can improve the quality of products like this and qualification rate, can save operation and time again.
Carboxy butyronitrile latex oil-resistant glove of the present invention is compared with existing oil-resistant glove, has following advantage:
1, this oil-resistant glove has excellent oil resistance energy and performances such as acidproof, alkaline-resisting, anti-solvent and wear-resisting, endurable thorn, is widely used in industrial department and domestic hygiene articles for use such as petrochemical industry, oil field oil refining, grease processing, aquatic products processing, mining machinery.
2, this oil-resistant glove is compared with the plastics oil-resistant glove with the rubber oil-resistant glove, have the quality softness, wearing is comfortable, winter is warming, summer absorbing sweat, characteristics such as elegant in appearance, be a kind of articles for labour protection that receive praises from customers.
