Abstract

The dry composite adhesive for high temperature steamed polyurethane bag is prepared with the following components in weight percent:
13.64 to 18.6 percent of diethylene glycol
23.26 to 25.73 percent of sebacic acid
2.06-2.94% of 1.2-propylene glycol
6 to 5.43 percent of isophthalic acid
3.86 to 5.74 percent of diphenylmethane diisocyanate
Ethyl acetate 48.71-44.03%
The manufacturing method comprises the following steps:
firstly, mixing diethylene glycol and sebacic acid, then adding 1, 2-propylene glycol and isophthalic acid, then carrying out polycondensation, reducing pressure to 755 mm Hg to generate polyester, then adding diphenylmethane diisocyanate to generate main adhesive, and finally adding ethyl acetate to dilute, thus completing the invention.

Description

Composite dry adhesive for high temperature steamed polyurethane bag and manufacture method
The present invention is a kind of polyurethane binder and manufacture method, in particular for the composite dry adhesive and the manufacture method thereof of high-temperature retort bag.
The food product pack industry is to directly more and more higher together with the requirement that food carries out high temperature steaming together with food pack in the world today, use high-temperature retort bag can be directly the food of production to be encapsulated in to heat in the bag after with seasoning matter and be processed into prepared food to carrying out boiling more than 121 ℃, simplify the production technique of food, guaranteed the health reliability of food.Because pressure pad is made up of the combination of plastic film and plastic film or plastic film/aluminium film/plastic film, the tackiness agent dry type Compound Machining by anti-boiling between plastic film and the plastic film or between plastic film or the aluminium film forms, and has good binding property.And present existing tackiness agent such as Chinese patent " ZL87104917 " nontoxic polyurethane adhesive by name and preparation thereof, the greatest problem of this tackiness agent is that resistance to elevated temperatures is poor, can not under the situation of high temperature steaming, keep high-strength binding property, therefore to high temperature steaming packing bag and inapplicable.
Purpose of the present invention just provides a kind of have moisture-proof, resistant to elevated temperatures composite dry adhesive for high temperature steamed polyurethane bag and manufacture method.
Composite dry adhesive for high temperature steamed polyurethane bag of the present invention component by weight percentage is:
Glycol ether 13.64~18.6%
Sebacic acid 23.26~25.73%
A 1.2 propylene glycol 2.06~2.94%
M-phthalic acid 6~5.43%
Diphenylmethanediisocyanate 3.86~5.74%
Vinyl acetic monomer 48.71~44.03%
The manufacture method of composite dry adhesive for high temperature steamed polyurethane bag of the present invention is:
1. mix: glycol ether and sebacic acid are mixed to heat under the effect of nitrogen and amines catalyst, continue 25 hours, add 1.2 1 propylene glycol and m-phthalic acid then and under 200 ℃ ± 2 ℃ condition, continue 12 hours to 220 ± 2 ℃.
2. polycondensation: former process is decompressed to 755 mmhg, generates intermediate raw material polyester and waste water, useless alcohol.
3. addition: the polyester adding diphenylmethanediisocyanate that former process is generated is cooled to 90~100 ℃ of main glue of generation.
4. dilution: the main glue that will generate adds vinyl acetic monomer, is warming up to 80~90 ℃ and makes tackiness agent.
The invention has the advantages that this tackiness agent has high temperature resistant, moisture-resistant, advantage that bonding strength is high, use the boiling after 30 minutes in 121 ℃ salt solution of high-temperature retort bag that this tackiness agent makes, the intensity of its compound sticking does not have considerable change, is the desirable tackiness agent of food product pack industry production high-temperature retort bag.
Embodiment of the present invention are:
Example 1: count by weight percentage: get
Glycol ether 16.17% is 198kg
Sebacic acid 24.49% is 300kg
1.2 a propylene glycol 2.61% is 32kg
M-phthalic acid 5.72% is 70kg
Diphenylmethanediisocyanate 4.64% is 56.8kg
Vinyl acetic monomer 46.37% is 568kg
Its operation steps is:
1. mix: earlier the glycol ether of 198kg and the sebacic acid of 300kg are mixed, heat to 220 ℃, under the effect of nitrogen and amines catalyst, kept 25 hours, add 32kg1.2 one propylene glycol and 70kg m-phthalic acid afterwards, under 200 ℃ condition, kept 12 hours.
2. polycondensation: former process is decompressed to 755 mmhg, generates intermediate raw material polyester 510kg, waste water 75.5kg, useless pure 14.5kg.
3. addition: the 510kg polyester that former process is produced adds the diphenylmethanediisocyanate of 56.8kg, generates main glue 566.8kg under 90 ℃~100 ℃ condition.
4. dilution: the main glue of 566.8kg is added the vinyl acetic monomer of 568kg, under 85 ℃ condition, vapor away the 1.2kg ethyl ester, generate tackiness agent 1133.6kg.
Example 2: count by weight percentage, get
Glycol ether 13.64%
Sebacic acid 25.73%
A 1.2 propylene glycol 2.06%
M-phthalic acid 6%
Diphenylmethanediisocyanate 3.86%
Vinyl acetic monomer 48.71%
Its operating process is with embodiment 1.
Example 3: count by weight percentage, get
Glycol ether 18.6%
Sebacic acid 23.26%
A 1.2 propylene glycol 2.94%
M-phthalic acid 5.43%
Diphenylmethanediisocyanate 5.74%
Vinyl acetic monomer 44.03%
Its operating process is with embodiment 1.
Just can realize the present invention according to the above.
