Abstract
The invention discloses a preparation method for a polyvinyl chloride material for a medical mask. The method comprises the following steps that, firstly, all the components are thrown into a high speed stirring machine according to weight proportion, and stirring and mixing are carried out for 20-40 minutes; secondly, the evenly mixed materials are added to a double-screw extrusion machine to be melted, plasticized, extruded and pelletized to obtain the polyvinyl chloride material for the medical mask. The preparation method is short in procedure, easy to operate, low in cost, environmentally friendly and high in economic benefit. Compared with the prior art, the polyvinyl chloride material for the medical mask prepared through the method has excellent biocompatibility and safety, and the performance of the material is better than that of related products on the market.
Description
Technical field
The invention belongs to polymeric material field, relate to a kind of preparation method of medical mask pvc material.
Technical background
Plastics, as a kind of very important material, are widely applied at medicine and hygiene fields.It both can be made into disposable medical instrument as dropping bottle, syringe etc., can be used for again non-once medical facilities as gauger, surgery instrument etc., and medical plastic field is current plastics industry one of market having development potentiality most.
Along with the sustainable growth of population in the world quantity, particularly aging populations and the increase of number suffering from chronic disease, facilitate the sustainable growth of medical services market, special medical apparatus obtains widespread demand.Due to macromolecular material excellent specific property and also can reduce costs, at present, medical treatment product and apparatus are from large-scale diagnostic instrments, disposable medical article so that meticulous artificial organ all be unable to do without macromolecular material, and macromolecular material becomes one of important raw and processed materials of medical treatment product and apparatus gradually.And at present, in respiratory system field, the plastics relevant to respirator are that plastics apply one of the most concentrated field in medicine equipment, face shield uses one of maximum plastics in medical instruments field, and these goods are mostly prepared from by materials such as polyethylene, polyvinyl chloride, polypropylene, rubber.The product of this class is the easily-consumed products that quantity is larger, and China consumes the value of this series products every year at about several hundred million yuans, and market is very huge.Current China can autonomous production respirator and associated plastic goods thereof, but due to factors such as product finenesses, product is mainly used in small and medium-sized cities and vast Rural areas or outlet, and mainly apply as metropolitan markets such as Beijing-Tianjin Shanghai or external imported product, therefore the market space is still very large.Due to contact with liquid or and human contact, the basic demand of medical grade plastic materials has chemical stability and biological safety.In simple terms, the moiety in plastic material can not be separated out and enter liquid or human body, can not cause toxicity and the damage of histoorgan, is nontoxic to human body.For improving blood compatibility, the histocompatibility of goods, need the modifying surface to goods.The plastic tool anti-infection property of interposing catheter and life-time service is also one of research and development direction of current medical grade plastic materials.In sum, a kind of property separated out is low, security is high medical mask plastic material is badly in need of providing to be this area technical problem urgently to be resolved hurrily.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of preparation method of medical mask pvc material is provided.
The object of the invention is to be achieved through the following technical solutions: a kind of preparation method of medical mask pvc material, said method comprising the steps of: the 1st step, by weight, by polyvinyl chloride 80-90 part, polyacrylic rubber 50-60 part, polyvinylpyrrolidone 12-15 part, silicon rubber 20-30 part, isoprene-isobutylene rubber 20-30 part, acetyl citrate 4-14 part, magnesium borate crystal whisker 2-7 part, nucleator 4-12 part, antiseptic-germicide 4-8 part, straw powder 5-15 part, multipolymer 3-5 part of vinylbenzene and divinyl, calcium carbonate 2-4 part, fimbrin 3-8 part, 2-thiol group benzimidazolyl 3-7 part and toughner 10-14 part are dropped in homogenizer, be uniformly mixed 20 ~ 40 minutes, 2nd step, the material mixed joined melting in twin screw extruder, plastify, extrude, granulation, to obtain final product.
Described extrusion temperature is 140 ~ 160 DEG C.Described nucleator is (3,4-dimethyl two benzal) sorbyl alcohol or methylene-bis (2,4-di-tert-butyl-phenyl) phosphoric acid ester oxyaluminum salt.
