Abstract
This invention is a preparation method of environmental bone glue adhesive. First, solid bone glue particles are mixed with water as quality ratio 1:1~1:1.5 to form liquid cement. Constant liquid bath is done at 60~700C, solid pure citric acid 4~6 portions are added when it is liquid bath every 100 portions, then it is agitated degradation to form liquid cement. Secondly, temperature is down to 40~450C, 3.5~4.5 portions of chloroepoxy propane of every 100 portions is added for agitating at 600 rotation every minute, the raction time is 1.5 hours. pH value is adjusted by acid and alkali t 7~7.5 and cooled down to room temperature, and the adhesive is got. Collagen big molecule is fully degradation by acid solution is added. The defect of bone viscosity is down by temperature down is conquered by control reaction temperature and time. Bone glue solidifying point is down and its bonding intension is improved.
Description
Technical field
The present invention relates to a kind of synthetic method of tackiness agent, particularly a kind of preparation method of environmental protection bone glue adhesive.
Background technology
Gelatine, hide glue are the parts of utilizing people's anorexia such as depleted animal bone, skin and tendon to use, a kind of tackiness agent that obtains through simple process, once be output maximum, most widely used timber and paper tackiness agent, its principal feature is that intensity height, collapsibility are good, nontoxic, pollution-free, cost is low.But the gelatine viscosity with temperature changes and takes place to change on a large scale, the about 70mPas of its viscosity very low (20% solid content) when being higher than 40 ℃ when temperature, along with decrease of temperature, viscosity sharply rises, when temperature is lower than 30 ℃, basically lose flowability and be gel state, thereby influenced the flowability of coating, this brings the difficulty that can't overcome just for the control of industrialized production and operation.Gelatine easily goes mouldy in addition, stores and transports and all have any problem.After white glue with vinyl occurs, gelatine uses inconvenience because of it, need the scene to boil, rate of drying is slower, withdraws from the market gradually, makes the gelatine business failure bankruptcy of the tens thousand of family of China, resources such as a large amount of discarded bones are underutilized, and make the pre-treatment work of bone meal producer complicated, and objectionable constituent such as the formaldehyde of interpolation more than in the gelatine product of modification, contaminate environment.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of preparation technology is provided the preparation method of simple environmental protection bone glue adhesive, according to said method Zhi Bei gelatine cohesive strength height, zero pour is low, easy to use.
For achieving the above object, the preparation method that the present invention adopts is: at first solid gelatine particle is mixed with the mass ratio of water by 1: 1～1: 1.5, make gelatine particle complete swelling form glue; Under 60～70 ℃ of conditions, carry out water bath with thermostatic control, by the pure citric acid of solid that adds 4～6 parts in the per 100 parts of glues of mass fraction, stirred 0.5～1 hour during water-bath, the glue after the formation degraded swelling; Be cooled to 40 ℃～45 ℃, by the epoxy chloropropane that adds 3.5～4.5 parts in the glue after the per 100 parts of degradeds of mass fraction, stir with 600 rev/mins speed, glue generation copolymerzation with cross-linking reaction after making epoxy chloropropane and degrading, reaction times is 1～1.5 hour, the reaction back is cooled to room temperature with acid-alkali accommodation pH value=7～7.5, promptly gets tawny viscous liquid tackiness agent.
Because the present invention is fully degraded the collagen macromole by adding acidic solution, and having overcome the gelatine viscosity with temperature by the strictness control to temperature of reaction, reaction times descends and the rapid shortcoming that rises, reduced the gelatine zero pour, further improved the bonding strength of gelatine, thereby make the bone glue adhesive that obtains after the modification except that keeping original good characteristic such as nontoxic, harmless, pollution-free, also have under the normal temperature be in a liquid state, good stability, tensile strength height, characteristics such as rate of drying is fast, low-temperature performance is good.
