Description
Technical field
The present invention relates to a kind of leaching and mould liquid and preparation method thereof, particularly liquid and preparation method thereof is moulded in a kind of light face pvc leaching.
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
The present invention is exactly the toxicity problem in order to solve existing PVC product, provides a kind of light face pvc of safety and environmental protection to soak and moulds liquid.
For this reason, in the present invention, liquid is moulded in the leaching of light face pvc, is made up of: PVC paste resin 48%-52% the material of following mass percent; Softening agent 39%-40%; Stablizer 2.3%-3%; Viscosity-depression agent 4%-5%; Calcium carbonate 0-5%; Defoamer 0.2%; Colorant 0.2%-0.8%.
Preferably, 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 smooth face pvc leaching to mould the preparation method of 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 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 micro-blue light face and mould liquid; The mass percentage content of described composition is: PVC paste resin 48%-52%; Softening agent 39%-40%; Stablizer 2.3%-3%; Viscosity-depression agent 4%-5%; Calcium carbonate 0-5%; Defoamer 0.2%; Colorant 0.2%-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.
