Abstract
The invention discloses a kind of food packaging adhesive, by mass fraction, it is made up of following component：50 ~ 55 parts of polyester diol, 65 ~ 70 parts of ethyl acetate, 2 ~ 3 parts of phthalic anhydride, 12 ~ 15 parts of epoxy resin, 10 ~ 12 parts of isophorone diisocyanate trimer, 0.1 ~ 0.2 part of phosphoric acid.Preparation method is as follows：Step 1：The polyester diol of formula ratio, ethyl acetate, phthalic anhydride, phosphoric acid, epoxy resin are placed in reactor, 60 DEG C is warming up to, turn on agitator, stirs 4h；Step 2：Isophorone diisocyanate trimer is added in the mixed liquor to stirring, after stirring, normal temperature is cooled to and produces food packaging adhesive.Food packaging adhesive water-tolerant produced by the present invention, solid content is high in adhesive, and rate of drying is fast during bonding.
Description
Technical field
The present invention relates to a kind of food packaging adhesive and preparation method thereof, applied to adhesive processing technique field.
Background technology
Adhesive is that development of modern industry and human living standard improve essential important materials, modern economy,
Significant role is played in national defence and modern science and technology, water-borne polyurethane bond is commonly used in food packaging applications, due to emulsifying agent
Using or molecule in hydrophilic and ionic groups introducing, make the reduction of water-borne polyurethane bond water resistance, and the water-based poly- ammonia of in the market
Ester gum solid content reduces, and rate of drying is slower.
The content of the invention
Above-mentioned to solve the problems, such as, the invention discloses a kind of food packaging adhesive and preparation method thereof.
The invention discloses a kind of food packaging adhesive, by mass fraction, it is made up of following component：Polyester diol
50 ~ 55 parts, 65 ~ 70 parts of ethyl acetate, 2 ~ 3 parts of phthalic anhydride, 12 ~ 15 parts of epoxy resin, isophorone diisocyanate three
10 ~ 12 parts of polymers, 0.1 ~ 0.2 part of phosphoric acid.
Above-mentioned epoxy resin is 1002# epoxy resin.
The preparation method of the present invention is as follows：
Step 1：The polyester diol of formula ratio, ethyl acetate, phthalic anhydride, phosphoric acid, epoxy resin are placed in reactor
It is interior, 60 DEG C are warming up to, turn on agitator, stirs 4h；
Step 2：Isophorone diisocyanate trimer is added in the mixed liquor to stirring, after stirring, is cooled to often
Temperature produces food packaging adhesive.
Using the technical program, the beneficial effects of the invention are as follows：Obtained food packaging adhesive water-tolerant, gluing
Solid content is high in agent, so that it is guaranteed that rate of drying is very fast during bonding.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Specific embodiment is closed, the present invention is expanded on further.
Embodiment one：
The invention discloses a kind of food packaging adhesive, by mass fraction, it is made up of following component：Polyester diol 50
Part, 67 parts of ethyl acetate, 2 parts of phthalic anhydride, 15 parts of epoxy resin, 10 parts of isophorone diisocyanate trimer, phosphoric acid
0.1 part.
Embodiment two：
The invention discloses a kind of food packaging adhesive, by mass fraction, it is made up of following component：Polyester diol 52
Part, 68 parts of ethyl acetate, 2.5 parts of phthalic anhydride, 15 parts of epoxy resin, 12 parts of isophorone diisocyanate trimer, phosphorus
0.15 part of acid.
The preparation method of the present invention is as follows：
Step 1：The polyester diol of formula ratio, ethyl acetate, phthalic anhydride, phosphoric acid, epoxy resin are placed in reactor
It is interior, 60 DEG C are warming up to, turn on agitator, stirs 4h；
Step 2：Isophorone diisocyanate trimer is added in the mixed liquor to stirring, after stirring, is cooled to often
Temperature produces food packaging adhesive.
Finally it should be noted that：Above example only not limits technology described in the invention to illustrate the present invention
Scheme；Therefore, although this specification with reference to above-mentioned each embodiment to present invention has been detailed description, this
Field it is to be appreciated by one skilled in the art that still can be modified to the present invention or equivalent substitution；And all do not depart from this
The technical scheme of the spirit and scope of invention and its improvement, it all should cover in scope of the presently claimed invention.
