Abstract
A hot melt adhesive for bonding polyolefin plastic belongs to the technical field of food packaging, and can be used as a polyolefin thin film for packaging foods and used for bonding polyolefin and paper and polyolefin and aluminum products. The molecular structure of the material is similar to the polyolefin, and further the material has certain polarity which refers to the fact that polyolefin can be melted on one hand, and other materials with the polarity can be effectively bonded on the other hand, such as ethylene-vinyl acetate copolymer, ethylene acrylate copolymer, ethylene-vinyl acetate-vinyl alcohol copolymer, derivative products of rosin and petroleum resin are added for strengthening adhesive, and paraffin wax products assist to have effects of infiltration and infiltration. The hot melt adhesive is simple in construction and safe and healthy, and has good adhesive force on the polyolefin thin film polyolefin and paper, aluminum products and the like and certain peel strength.
Description
Technical field
A kind of hot melt adhesive of bonding polyolefin plastics belongs to the Food Packaging technology field.
Background technology
Corona treatment needs external conditionss such as certain device, especially some material, electrical treating meeting that is used for food, electron trade is brought some negative influences.For this reason, seek a kind of very necessity of the tackiness agent simple, that certain bond strength is arranged of constructing.
Summary of the invention
The object of the invention is to seek a kind of jointing material, and its molecular structure has and the very similar structure formation of polyolefine, but has certain polarity simultaneously.Like this, according to the molten rule of phase patibhaga-nimitta, they can fuse with polyolefine, and the polar structure that has in the molecule on the other hand again can be effectively bonding with other material.
Technical scheme of the present invention: a kind of hot melt adhesive of bonding polyolefin plastics; Described hot melt adhesive is made up of base material, tackify material, viscosity modifier, softening agent, and the accounting of base material is 10%-45% in mass, and tackify material accounting is 10%-40%; The viscosity modifier accounting is 10%-40%; The softening agent accounting is 5%-20%, and according to the bonding purposes of difference, accounting is regulated; With the mixed mutually hot melt adhesive product that promptly makes of above material;
Said base material is selected ethene-acetate ethylene copolymer for use, ethylene acrylate copolymer, or ethene-vinyl acetate between to for plastic-vinyl alcohol copolymer;
Said tackify material selection rosin, staybelite, polymerized rosin or their glyceryl ester, or select carbon 5 or carbon 9 petroleum resin for use;
Said viscosity modifier is selected paraffin, microcrystalline wax or polyethylene wax for use;
Said softening agent is selected phthalate, white oil, epoxy soybean oil or butyl citrate for use.
Prepared hot melt adhesive all has good cohesiveness to polyolefin film and polyolefin film, polyolefine and paper, polyolefine and aluminium.
The material that is suitable for this requirement can be an Injecatable EVA Copolymer, ethylene acrylate copolymer, ethene-vinyl acetate between to for plastic-vinyl alcohol terpolymer.
Injecatable EVA Copolymer:
Ethylene acrylate copolymer
R can be H, or-CH
2-CH
3,-CH

3Deng,
Ethene-vinyl acetate between to for plastic-vinyl alcohol terpolymer:
Though above-mentioned copolymeric material has good adhesive property with polyolefine; But its force of cohesion is very strong, and polyolefine and other material bond strength is relatively poor, for adapting to polyolefine and other material bond strength; Also must increase the tackify material; These materials and aforementioned substrates have excellent compatibility, and itself are with polarity and ring type structure that the sticking material of the quilt of various band polar structure is had bonds well property, this type material such as rosin and verivate thereof
And petroleum resin
In addition, in order to guarantee that hot melt adhesive to by sticking material good infiltration and coating being arranged, also need add viscosity modifier, this type material such as paraffin, microcrystalline wax or polyethylene wax etc.
For making mucous membrane overcome cold shortness, increase flexibility, also need add softening agent, phthalate for example is to being used for food and food product pack, available white oil, epoxy soybean oil, butyl citrate etc.
Above various types of materials is fused in proportion, made hot melt adhesive between the polyolefin film, polyolefine and paper, polyolefine and aluminium etc. have good bounding force and certain stripping strength.
Beneficial effect of the present invention: base materials employed its molecular structure of hot melt adhesive of the present invention and polyolefins seemingly also have certain polarity, and one side and polyolefine can fuse; Can be with the polar material effectively bonding with other again on the other hand; Like Injecatable EVA Copolymer, ethylene acrylate copolymer etc., the derived product of adding with rosin and petroleum resin carries out tackify; Be aided with the paraffin class product, soak into and the coating effect to play.Simple, the safety and sanitation of hot melt adhesive construction that the present invention is made have good bounding force and certain stripping strength to polyolefin film, polyolefine and paper, polyolefine and aluminium etc.
