Description
Technical field
The present invention relates to a kind of leaching and mould liquid and preparation method thereof, particularly relate to the leaching of a kind of pitted skin polyvinyl chloride and mould liquid and preparation method thereof.
Background technology
PVC leaching is moulded liquid and can be widely used in the coating of the products such as physical fitness equipment, labour protection PVC glove, hardware & tools handle, handle, iron wire clothes hanger, hook, insulating material, soft rubber sleeve glue beans, artwork, valve handle, automobile (motorcycle) theftproof lock sheath.All a certain amount of softening agent will be added in its process of manufacture, and conventional softening agent is phthalate, as phthalic acid two (2-ethyl) ester (DOP or DEHP), dibutyl phthalate (DBP), O-phthalic dinonyl (DINP), the different certain herbaceous plants with big flowers ester (DIDP) of phthalic acid two and phthalic acid n-octyl (DNOP) etc., such elasticizer plasticizing better performances, cost is lower, but large to the hazardness of human body and environment, liquid can not be moulded for the preparation of the PVC leaching of environmental protection.
At present, European Union and the U.S. launch respectively the use that relevant laws and regulations policy limits adjacent benzene class softening agent: European Union's toy safety directives prescribe: in various toy material, the total content of DEHP, DBP, BBP, DINP, DIDP, DNOP6 kind plasticizer materials must not more than 0.1%.And the toy of DEHP, DBP and BBP concentration more than 0.1% and articles for children do not allow to enter EU market; The U.S. has stopped production 6 kinds of phthalic acid lipid softening agent, and USEPA has also started to be limited in the higher industry of the environmental requirements such as toy, articles for children, medical article, packaging material for food and used phthalic ester plasticizer.Wherein, the forbidding scope of DINP, DIDP and DNOP tri-kinds of softening agent is extended to may be put into the toy of mouth and the plastics of articles for children by less than 3 years old and 3 years old child, even comprises in leatheroid and garment making industry ink and also prohibits the use adjacent benzene class softening agent.In recent years, China's PVC product outlet receives extreme shock in the international market, again and again spread out of plastics and be exported to the message that the country such as European Union denies entry, its one of the main reasons be exactly softening agent not environmentally, become " stumbling-block " that limit the outlet of these industries.And the key solving this series of problems is to use environment-friendly plasticizer to prepare environment-friendly PVC goods.
Summary of the invention
Object of the present invention solves the virose problem of existing softening agent exactly, provides a kind of pitted skin polyvinyl chloride of safety and environmental protection to soak and moulds liquid.
Liquid is moulded in a kind of pitted skin polyvinyl chloride leaching, and it is made up of the material of following mass percent: PVC suspending resin powder 23%-24%, PVC paste resin 24%-26%; Softening agent 35%-38%; Stablizer 2%-3%; Viscosity-depression agent 3%-5%; Calcium carbonate 5-10%; Defoamer 0.2%-0.4%; Colorant 0.5%-0.8%.
Preferably, softening agent is citrate plasticizer.
Preferably, stablizer is pasty state calcium-zinc composite stabilizing agent.
Preferably, viscosity-depression agent is Porous deproteinized bone hydrocarbon polymer.
The present invention provides a kind of pitted skin polyvinyl chloride to soak the preparation method moulding liquid simultaneously, and it comprises the steps:, and softening agent, stablizer, viscosity-depression agent, defoamer, colorant are added stirring tank by (1), stir 1 hour; (2) PVC suspending resin, paste resin, calcium carbonate are added stirring tank, after material adds, seal kettle cover, keep the vacuum tightness of 0.05MPa to stir 1 hour; (3) keep the vacuum tightness of 0.09-0.1MPa continuation stirring within 2-3 hour, namely to obtain the leaching of blue pitted skin and mould liquid.The mass percentage content of above-mentioned composition is: PVC suspending resin powder 23%-24%, PVC paste resin 24%-26%; Softening agent 35%-38%; Stablizer 2%-3%; Viscosity-depression agent 3%-5%; Calcium carbonate 5-10%; Defoamer 0.2%-0.4%; Colorant 0.5%-0.8%.
Preferably, softening agent is citrate plasticizer.
Preferably, stablizer is pasty state calcium-zinc composite stabilizing agent.
Preferably, viscosity-depression agent is Porous deproteinized bone hydrocarbon polymer.
The present invention has following beneficial effect: use citric acid ester type novel environment-friendlyplasticizer plasticizer to replace the adjacent benzene class softening agent such as DOP, DINP, stop adjacent benzene class softening agent as the possibility of a kind of carcinogenic substance to harm, made product reach the requirement of safety and environmental protection completely.
