Abstract
The invention discloses a preparation method of an environment friendly adhesive, comprising the following steps: adding 5-30% by mass of soybean protein isolate into water, and stirring uniformly to obtain a soybean protein isolate liquid; placing the soybean protein isolate liquid into an ultrasonic cleaning device for ultrasonic processing at the temperature of 30-50 DEG C for 20-40min; adding 0.1-5% by mass of sodium dodecyl sulfate, and stirring for 1-2h; then adding 2-10% by mass of boric acid and 1-5% by mass of bamboo vinegar and stirring for 1-2h, and uniformly stirring to obtain the environment friendly adhesive. When the preparation method of the environment friendly adhesive in the invention is used in the process of modifying a soybean protein isolate adhesive, the reaction core of a soybean protein can be exposed through ultrasonic waves, and the chemical modification of the sodium dodecyl sulfate and the chemical modification of the boric acid are combined, thus, the bonding strength and the hydrophobicity are enhanced, the water resisting property of the adhesive is enhanced; and a biologic mould inhibitor and the bamboo vinegar are combined, and thus, the antibiotic property is enhanced.
Description
Technical field
The present invention relates to a kind of tackiness agent, especially relate to the preparation method of environment-friendly adhesive.
Background technology
At present, China's wood working stick with glue agent still " three-aldehyde glue " be main, account for whole timber and wood-based panel industry and stick with glue more than 80% of agent.Yet such adhesive made of synthetic resin can constantly discharge phenol and formaldehyde in production, transportation and use, bring environmental problem.In recent decades, the expansion in tackiness agent market, in the global range petroleum resources day by day exhaustion and problem of environmental pollution be subjected to people day by day and pay close attention to, force adhesives industries, rethink research and development new type natural tackiness agent.
Bamboo vinegar liquid is that bamboo wood is fired a kind of by product that forms in the bamboo charcoal process at high temperature pyrolysis, studies show that bamboo vinegar liquid is a kind of natural bacteriostatic agent and sterilant, having a extensive future of aspects such as mildew-resistant, PCO.
Summary of the invention
The present invention combines the characteristic and the bamboo vinegar liquid biocidal property of natural adhesive environment-friendly type, and a kind of environment-friendly adhesive is provided.
The present invention gets the preparation method of environment-friendly adhesive, it is characterized in that: described preparation method is added to the water soybean protein isolate, additional proportion is a mass percent 5%～30%, stir, obtain soybean protein isolate solution, place ultrasonic cleaning machine under 30～50 ℃ of temperature, supersound process 20～40min adds sodium lauryl sulphate, and additional proportion is a mass percent 0.1%～5%, stir 1～2h, add boric acid and bamboo vinegar again, stir 1～2h, additional proportion is a mass percent boric acid 2%～10%, bamboo vinegar 1-5%
After stirring promptly.
Described soybean protein isolate additional proportion is a mass percent 15%～25%.
The additional proportion of described sodium lauryl sulphate is a mass percent 0.5%～2%.
The additional proportion of described boric acid is a mass percent 5%～6%.
The preparation method of environment-friendly adhesive of the present invention at first carries out supersound process and carries out physically modified in preparation process, by hyperacoustic cavitation, mechanical effect and super melange effect etc., impel chemical bond rupture, form and the more reactive centers of exposure, therefore soybean isolated protein adhesive is being carried out modifying process, ultrasonic wave can make the reactive center of soybean protein come out, thereby the chemical modification in conjunction with sodium lauryl sulphate and boric acid reaches increase bonding strength and hydrophobicity again, improve the water tolerance of tackiness agent, and biological mould inhibitor bamboo vinegar combines, and strengthened germ resistance.
Embodiment
Below in conjunction with specific embodiment component of the present invention is described further:
Embodiment 1
Soybean protein isolate is added to the water, and additional proportion is a mass percent 15%, stirs, obtain soybean protein isolate solution, place ultrasonic cleaning machine under 50 ℃ of temperature, supersound process 40min, add sodium lauryl sulphate, additional proportion is a mass percent 5%, stirs 2h, adds boric acid and bamboo vinegar again, stir 2h, additional proportion is a mass percent boric acid 2%, bamboo vinegar 1%, after stirring promptly.
The above; only be the preferable embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
