Abstract
The invention discloses a high-strength aluminum film plating compound adhesive and a preparation method of the high-strength aluminum film plating compound adhesive. A main adhesive body is polyester polyol with a dimer acid structure, a curing agent is a NCO prepolymer with a dimer acid structure, and the ratio of the main adhesive body to the curing agent is 5:1 to 5:1.5. Because both the adhesive body and the curing agent have the long-chain structures of dimer acid, mutual permeation between an organic interface and an inorganic interface can be improved through a coupling agent, and combined strength is improved. A colloid obtained after the main adhesive body of the long-chain structure and the curing agent of the long-chain structure are mixed is softer and higher in cohesion, an adhesive layer formed by compositing the colloid and a polyester film is high in bonding strength and good in softness, the bonding force between an aluminum-plated layer and the polyurethane adhesive layer is similar to that between an external plastic base material and the aluminum-plated layer, the factors which can easily cause stripping of the aluminum-plated layer from the external plastic base material are eliminated, the phenomenon that an aluminum-plated layer shifts can be eliminated, bonding strength is improved, and corrosion resistance is better.
Description
Technical field:
The present invention relates to a kind of high strength aluminium plating film composite adhesive and preparation method thereof.
Background technology:
Aluminium plating film wrapped product has heat insulation, anti-optical transmittance property, appearance gloss is attractive in appearance simultaneously, and pack cheap, therefore extensive employing is obtained in outer packagings such as snackfoods, medicine, makeup such as Biscuit class, dry puffed food, smoked plums, in recent years, the soft packaging of beverage, fluid flavoring also brings into use aluminium plating film to pack, and tempo is very fast, and market outlook are very wide.Although aluminium plating film has lot of advantages in the packing of product, also exist following not enough:
During film composite aluminium-plated with conventional polyurethanes glue, the aluminium lamination of aluminium plating film easily shifts, thus causes the aluminium coated of composite membrane and plastic basis material to peel off, and causes aluminium plating film combined strength bination to reduce.Its major cause is that conventional polyurethanes tackiness agent structure is comparatively hard, and between aluminium coated and urethane glue-line, bounding force is greater than the bounding force of outer layer plastic base material and aluminium coated, easily causes aluminium coated and outer layer plastic base material to be peeled off, makes aluminium plating film packing film strength degradation.Along with the raising that food and drug safety requires, people are managing to extend food, medicine, the quality guaranteed period of the liquid products such as beverage, wherein, improving packing instructions is crucial technological approaches, although existing aluminium plating film packaging has excellent specific property, but the stripping strength of existing aluminium plating film packaging is too low, according to newest research results, the stripping strength of packing for the aluminium plating film of this kind of high-end article is necessary >=3.0N/15mm, otherwise just can not meet the demands, and the stripping strength of the existing aluminium plating film packaging of China is all less than 2.0N/15mm, applicant is through Indexing of Scien. and Tech. Literature and market study, up to the present, market also there is no satisfactory high strength aluminium plating film composite adhesive, high strength aluminium plating film composite adhesive will become following food, medicine, the main flow of the extraordinary material package such as beverage, the market requirement is very urgent.
Sichuan Ailun Technology Co., Ltd. discloses a kind of preparation method of Mo compound binding agent of aluminizing in Chinese patent 201210169223.1, it is the preparation method of two component solvent-borne type aluminium plating film compound binding agent, wherein, polyester polyol preparation in main glue is spent glycol, glycol ether totally 0.8 ~ 0.9mol and terephthalic acid 0.2 ~ 0.3mol stirs and is warmed up to 180 DEG C, add the tetra isopropyl titanate catalyzer of 82PPM, continue to be warming up to 190 DEG C, when the water produced in reaction system reaches theoretical amount, add neopentyl glycol, neopentyl glycol is totally 0.3 ~ 0.4mol, m-phthalic acid, at least one in phthalic anhydride and adipic acid totally 0.7 ~ 0.8mol, continue to be incubated 4 hours when being warming up to 230 DEG C ~ 235 DEG C, insulation terminates rear sampling and detects, as Suan Zhi≤14mgKOH/g, during Qiang Zhi≤120mgKOH/g, open vacuum pump, the esterifying polycondensation 2 hours when vacuum tightness reaches-0.098MP, obtain polyester polyol, sampling detects, Suan Zhi≤1mgKOH/g, Qiang Zhi≤55 ± 2mgKOH/g, wherein, more than one dibasic alcohol, diprotic acid and acid anhydrides all coordinate with any molar ratio.
Although this polyester polyol and corresponding solidifying agent are with the use of the stripping strength that can improve aluminium plating film, can not more than 2.0N/15mm, the stripping strength of its polyester film compound different from three kinds is as follows:
(1) stripping strength of polyester film/polyester aluminium plating film is 1.8 ~ 2.0N/15mm;
(2) stripping strength of polypropylene screen/polyester aluminium plating film is 1.7 ~ 2.0N/15mm;
(3) stripping strength of polypropylene screen/salivation polypropylene aluminium plating film reaches 1.4 ~ 1.6N/15mm,
Although this tackiness agent is higher than common aluminium plating film stripping strength as can be seen here, the high-end aluminium plating film packing instructions that stripping strength is greater than 3.0N/15mm can't be met.
In order to meet the need of market, applicant carries out long-term research and test to it, successfully develops the aluminium plating film composite adhesive of Bao from Qiang Du≤3.0N/15mm, and has grasped its preparation method.
Summary of the invention:
The object of this invention is to provide a kind of high strength aluminium plating film composite adhesive and preparation method thereof, its Bao, from Qiang Du≤3.0N/15mm, can meet high-end aluminium plating film packing instructions.
A kind of high strength aluminium plating film composite adhesive, is made up of main glue and solidifying agent, it is characterized in that: main glue is the polyester polyol containing dimeracid structure, and solidifying agent is the NCO performed polymer containing dimeracid structure, and main glue and solidifying agent proportioning are 5:1 ~ 5:1.5.
