Abstract
The invention relates to a heat seal glue which comprises the raw material in percentage by weight: 35-40% of acetic ether, 15-25% of chloric vinegar, 10-15% of organic silicon modified polyurethane resin and 0.5-1.2 wt% of wax, wherein the molecular weight of the organic silicon modified polyurethane resin is 200,000-300,000. The heat seal glue prepared by the technical scheme can reach the requirement of directly and indirectly contacting foods, and belongs to safe and environmentally-friendly substance harmless to human bodies. In addition, while satisfying the requirement of heat seal packaging, the heat seal glue does not chemically degrade at high temperature (the heat seal glue can resist the high temperature of about 200 DEG C), does not pollute wrappage, does not affect the quality of the wrappage and is especially suitable for food packaging.
Description
Technical field
The invention belongs to the heat-seal adhesive field, particularly relate to a kind of fire resistant environment-friendly heat-seal adhesive that is applied to food product pack.
Background technology
In the package production of food, seal package technology is a most key link.Seal package technology is divided a variety of, and as washer sealing, rubber belt sealing and colloid sealing etc., wherein the colloid sealing is most widely used.
Colloid sealing divides cold envelope and heat-sealing again, though the cold envelope of normal temperature environmentally-friendly sanitary does not comparatively satisfy some to the demanding concrete application of stripping strength as the cold front cover of normal temperature.And the application of hot sealing process is more extensive, for example in the package production of candy, generally adopts to be coated with the mode that colloid seals in the inboard of candy wrapping mouth and to seal.
There are some problems in heat sealed package technology of the prior art, and sealing might touch food on the one hand, and existing sealing does not all reach the directly requirement of contact food; On the other hand, when the packaging seal film applied high temperature, physics or chemical transformation may take place in the colloid of film and sealing part, and chemical transformation especially takes place, and polluted thereby can produce sheathing foodstuff.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of heat-seal adhesive, its composition of raw materials is made up of 35%～40% vinyl acetic monomer, 15%～25% chlorine vinegar, 10%～15% organic silicon modified polyurethane resin, 0.5%～1.2% wax by weight percentage, the summation of all components is 100%, the molecular weight of described organic silicon modified polyurethane resin is 200,000～300,000.
The present invention also provides the preparation method of above-mentioned heat-seal adhesive on the other hand, according to the described composition of raw materials of claim 1 and corresponding ratio with each component stirring and evenly mixing.
Described stirring and evenly mixing is meant each component of composition of raw materials is mixed the mode of back by stirring, especially by the mode of high-speed stirring, makes each component mix.Those skilled in the art can select suitable stirring velocity according to the viscosity of composition of raw materials, the factors such as speed, preparation amount and batch can size of batch turning.
Adopt the heat-seal adhesive of technique scheme, it has not only reached and can directly contact or the requirement of food indirectly, belong to environment-friendly type, harmless security material, simultaneously also under high temperature (can anti-about 220 ℃ high temperature) decomposition can not take place in the requirement of satisfying heat sealed package in addition, can not produce and pollute packing material, can not have influence on the quality of packing material, be specially adapted to food product pack.
Embodiment
Below the specific embodiment of the present invention is described, but be not limited to these embodiment.
Embodiment 1
The preparation of raw material:
According to the heat-seal adhesive (pre-preparation 100kg heat-seal adhesive) of present embodiment, its composition of raw materials is as follows: 66kg vinyl acetic monomer, 20kg chlorine vinegar, 13kg organic silicon modified polyurethane resin (molecular weight is 250,000), 1kg wax.
The preparation of heat-seal adhesive:
Successively vinyl acetic monomer, chlorine vinegar, organic silicon modified polyurethane resin, wax are poured in the agitation vat, high-speed stirring (stirring velocity was about for 30 circle/seconds), stirring makes organic silicon modified polyurethane resin and wax fully dissolve and the material thorough mixing evenly (approximately needs to stir 30 minutes), promptly obtains the present embodiment heat-seal adhesive.
More than the present invention has been done detailed description; its purpose is to allow the personage that is familiar with this art can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences of doing according to spirit of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
1. heat-seal adhesive, it is characterized in that: its composition of raw materials is made up of 35%～40% vinyl acetic monomer, 15%～25% chlorine vinegar, 10%～15% organic silicon modified polyurethane resin, 0.5%～1.2% wax by weight percentage, the molecular weight of described organic silicon modified polyurethane resin is 200,000～300,000.
2. the preparation method of heat-seal adhesive as claimed in claim 1 is characterized in that: according to the described composition of raw materials of claim 1 and corresponding ratio with each component stirring and evenly mixing.
