Synthetic example 1

[0022] Synthesis Example 1 Synthesis Example of Polyester Resin

[0023] In a reaction kettle equipped with a stirrer, a thermometer, and a distillation condenser, add dibasic acid and dibasic alcohol according to the ratio of raw materials listed in Table 1, and carry out esterification reaction at 160°C to 230°C for 3 hours. Then, the pressure was reduced to 5 mmHg at 260° C. for 30 minutes, followed by polycondensation under high vacuum greater than 0.3 mmHg for 45 minutes to form an intermediate product. Then, return to normal pressure by introducing nitrogen gas. When the temperature of the reaction system drops to 210°C, add trimellitic anhydride and react for another 30 minutes. When the temperature of the reaction system drops to 110°C, add A-LinkTM35 according to the ratio in the table and react for 30 minutes. , to obtain polyester resins (A-1) to (A-5). The mass parts of their composition raw material consumption and the number average molecular weight of the polye...

[0028] Synthesis Example 2 Synthesis Comparative Example of Polyester Resin

[0029] In a reaction kettle equipped with a stirrer, a thermometer, and a distillation condenser, add dibasic acid and dibasic alcohol according to the ratio of raw materials listed in Table 2, and carry out esterification reaction at 160° C. to 230° C. for 3 hours. Thereafter, the pressure was reduced to 5 mmHg at 260° C. over 30 minutes, followed by polycondensation under a high vacuum of 0.3 mmHg or less for 45 minutes to form an intermediate product. Then, nitrogen was introduced to return to normal pressure. When the temperature of the reaction system dropped to 210°C, trimellitic anhydride was added and reacted for another 30 minutes. When the temperature of the reaction system dropped to 110°C, A-LinkTM35 was added in proportion and reacted for 30 minutes to prepare Polyester resins (B-1) to (B-4) were obtained. The mass parts of their raw material consumption and the number average molecular...

Embodiment 1

[0034] Dissolve 100 parts of polyester resin (A-1) in 35 parts of ethyl acetate, 5 parts of butyl acetate, 25 parts of methyl ethyl ketone, 15 parts of toluene, 10 parts of isopropanol, 5 parts of ethylene glycol monomethyl In the mixed solvent of ether and 5 parts of ethylene glycol monobutyl ether, epoxy resin, curing agent and chloroacetic acid resin were added according to the quantities listed in Table 3. After fully mixing, they were coated on 25 μm polyester film, polychloride On the corona-treated surface of the vinyl film, the film thickness after drying was about 3 μm. Dry with hot air at 100°C for 2 minutes to remove the solvent, laminate the adhesive surfaces of the polyester film and the polyvinyl chloride film with the steel plates heated at 170°C in advance, and press them with a hot roller at 200°C to obtain polyvinyl chloride films respectively. Ester film, PVC composite steel plate. The obtained composite steel plate material was subjected to various perform...

Abstract

The invention discloses a monocomponent reaction type hot-melt adhesive and steel composite material using the hot-melt adhesive, belonging to the steel composite material technical field, in order to satisfy the requirement of adhesive which is suitable for bonding with polyvinyl chloride film, polyester film and steet plate and not accretionary on rolling and steel composite material using the hot-melt adhesive. The hot-melt adhesive comprises 100 mass portion of polyester resin, 2-12 mass portion of epoxy resin, 0.08-0.8 mass portion of curing agent and 5-25 mass portion of chloroacetic acid. The steel composite material has excellent impact resistance and boiling water resistance. The adhesive can firmly be bonded with the polyvinyl chloride film, polyester film and steet plate, and the polyester film and polyvinyl chloride film coated with the adhesive are not accretionary and the coating life is long.

Description

technical field [0001] The present invention relates to an adhesive for a steel plate composite material and a steel plate composite material, more specifically, the present invention relates to a one-component reactive adhesive for a steel plate composite material and a steel plate composite material using the same. Background technique [0002] Decorative steel plate composite materials for home appliances, building materials, utensils, etc. are made by laminating plastic film (one of polyester film and polyvinyl chloride film) and steel plate with adhesive. In the past, polyvinyl chloride film was mostly used in the past. In recent years, there has been a trend of using polyester film to gradually replace polyvinyl chloride film to produce steel plate composite materials. [0003] The production of steel plate composite materials usually pre-coats the adhesive on the plastic film, winds it up, and finally heat-compresses it with the steel plate. Therefore, it is required...
