Abstract
The invention relates to a modified polyvinylidene chloride formula including polyvinylidene chloride resin, a plasticizer, a dispersant, an internal thermal stabilizer and a toughening agent; the formula comprises the raw materials in parts by weight: 100 parts of polyvinylidene chloride, 10-20 parts of the plasticizer, 1-5 parts of the dispersant, 0.1-1 part of the internal heat stabilizer, and 1-3 parts of the toughening agent. The modified polyvinylidene chloride formula has the beneficial effects that the melting temperature is reduced, the melting time is shortened, the thermal stability and liquidity are enhanced, the toughness is strengthened, and thus the competitiveness of products is increased.
Description
Technical field
The present invention relates to a kind of polyvinylidene dichloride formula, be specially a kind of modified polyvinilidene Ethylene Dichloride formula.
Background technology
Polyvinylidene dichloride (being called for short PVDC) resin is the perfect package material that a kind of barrier is high, toughness strong and low-temperature heat-sealing, heat-shrinkable and chemical stability are good of other monomer polymerization gained such as vinylidene chloride (VDC) and vinylchlorid (VC), vinyl cyanide, vinylformic acid and methyl acrylic ester.Except the general property with plastics, also there is the oxygen barrier of oil-proofness, erosion resistance, guarantor's taste and excellence, protection against the tide and fungicidal properties, directly can contact with food, also there is excellent printing performance simultaneously.Based on the good characteristic of PVDC resin, its purposes is very extensive, be widely used in that meat product, ready-to-eat, milk preparation, makeup, medicine and hardware, mechanical component, military supplies etc. variously need that anticorrosion, the every flavour guarantor of oxygen barrier is fragrant, water proof is moistureproof, oil removal permeation-proof etc. intercepts and requires the high packing of product, and exploitation prospect is very extensive.
But because polyvinylidene dichloride cl content is high and degree of crystallinity is high, melt temperature is high, and the fusion time is long; Also there is melt viscosity in addition large, poor fluidity, be heated and easily degrade, process-cycle is short, the shortcomings such as film is easy to change, and heat seal strength is low, elastic performance difference, limit it requires higher field development in over-all properties, also reduce the competitive power of itself and the high barrier such as ethylene-vinyl alcohol copolymer, polymeric amide material.
Summary of the invention
In order to solve the problem, the invention provides a kind of modified polyvinilidene Ethylene Dichloride formula, described formula is achieved through the following technical solutions:
A kind of modified polyvinilidene Ethylene Dichloride formula, described formula comprises polyvinylidene chloride resin, softening agent, dispersion agent, interior thermo-stabilizer, toughner, the each raw material weight component of described formula is: polyvinylidene dichloride 100 parts, 10 ~ 20 parts, softening agent, dispersion agent 1 ~ 5 part, interior thermo-stabilizer 0.1 ~ 1 part, toughner 1 ~ 3 part.
Described softening agent is phthalic acid two (2-ethyl hexyl) ester.
Described dispersion agent is the mixture of methylcellulose gum and Vltra tears.
The mass ratio of described mixture of dispersing agents methylcellulose gum and Vltra tears is 2:1.
Described interior thermo-stabilizer is glycidyl acrylic methyl esters.
Described toughner is methyl methacrylate-divinyl-styrene copolymer.
The invention has the beneficial effects as follows: reduce melt temperature, shorten the fusion time, enhance thermostability, and mobility, and strengthen toughness, thus increase the competitive power of product.
