Abstract
The invention relates to a process for preparing gelatine modified adhesive by using the common gelatine as principal raw material through moderate degradation, selecting a monomer containing epoxy radicals, under a finite condition, cross bonding copolymerization to obtain a binding agent produce. fine low-temperature freezing resistance property is also achieved.
Description
(1) technical field
The present invention relates to a kind of chemical industry articles for use, a kind of preparation method of tackiness agent is the preparation method of gelatine modified adhesive specifically.
(2) background technology
Gelatine be a kind of nontoxic, harmless, pollution-free, low-cost, have high-adhesive-strength, biodegradable water-soluble natural sizing material, its main drawback is that the glue zero pour is higher, is solid under the room temperature, needs heating and melting during use, uses inconvenience; Rate of drying is slow, and the objectionable constituent such as containing formaldehyde of adding in the modified product more, contaminate environment.
(3) summary of the invention
The invention solves gelatine glue zero pour height, the problem that rate of drying is slow.The present invention finishes by following steps: dissolve by 1: 1 weight ratio common gelatine and water (1) with gelatine, in the mixture of gelatine and water, add alkaline solution (sodium hydroxide solution) again, the solid content consumption of its alkali is 8～10% gelatine quality, degradation temperature is 70～80 ℃, and degradation time is 0.5～1 hour; (2) should guarantee reaction system PH=10～11 in the copolymerzation with cross-linking stage, select epoxy chloropropane as monomer, its epoxy chloropropane consumption is 8～10% gelatine quality, temperature of reaction is 60～70 ℃, reaction times is 1～2 hour, stirring velocity is answered PH=10～11 of guarantee system between the reaction period about 600 rev/mins; (3) be cooled to room temperature rapidly, mix siccative (as wilkinite) in reaction product, the consumption of its siccative is 2～8% glue quality, obtains the tawny viscous liquid, is product, and the room temperature sealing is preserved.The tackiness agent of the present invention preparation has kept gelatine tackiness agent bonding strength height, free of contamination advantage, has good low temperature anti-freezing property simultaneously, zero pour＜-5 ℃; Rate of drying is fast, room temperature following time of drying＜24 hours; Good stability, shelf time＞6 month; And generated time is short, and cost is low, the open application of gelatine modified product in timber, paper adhesive field.
(4) embodiment
The present invention is further detailed explanation below in conjunction with embodiment:
(1) this is reflected under the water bath with thermostatic control and carries out.In there-necked flask, take by weighing gelatine 25g, add 25g water, 60 ℃ of following stirring and dissolving; Be warming up to 80 ℃, get 2g sodium hydroxide and add in the mixture that water 8～10g wiring solution-forming adds gelatine and water, constant temperature stirs the 0.5h that degrades down.(2) be cooled to 70 ℃, drip epoxy chloropropane 2g, isothermal reaction 1.5h; Control PH=10～11 during this time.(3) be cooled to room temperature rapidly, mix the siccative of 2～8% glue quality such as wilkinite etc., promptly obtain the tawny viscous product.
Claims (2)
1, a kind of preparation method of gelatine modified adhesive is characterized in that (1) is dissolved in water common gelatine, degrades under alkaline condition; (2), make it to react with degraded product generation copolymerzation with cross-linking with containing the epoxy group(ing) monomer; (3) in reaction product, mix an amount of siccative, promptly get product bone-glue modified adhesive.
2, the preparation method of a kind of gelatine modified adhesive according to claim 1, it is characterized in that (1) is 1: 1 by the weight ratio of common gelatine and water, gelatine is dissolved, in the mixture of gelatine and water, add alkaline solution (sodium hydroxide solution), the solid content of its alkaline solution is 8～10% of a gelatine, degradation temperature is 70～80 ℃, and degradation time is 0.5～1 hour; (2) in copolymerzation with cross-linking elementary reaction system PH=10～11, select epoxy chloropropane as monomer, its epoxy chloropropane consumption is 8～10% gelatine quality, and temperature of reaction is 60～70 ℃, and the reaction times is 1～2 hour; (3) mix siccative (as wilkinite) in reaction product, the consumption of its siccative is 2～8% glue quality.
