Abstract
The invention provides a soybean meal-based adhesive and a preparation method thereof. The soybean meal-based adhesive comprises the following raw material in parts by weight: 20-30 parts of soybean meal flour, 74-58 parts of water and 5-10 parts of a compound cross-linking agent, and the used compound cross-linking agent is a mixture of a plurality of urea, polyvinyl alcohol, isocyanate type and amide type polymers. The soybean meal flour is taken as a raw material, acid treatment and heating treatment are performed in early stage, and the compound cross-linking modifier is adopted in late stage for cross-linking modification and preparation; and the preparation process has the advantages of simplicity, greenness, environment-friendly property and a wide range of applications. The adhesion strength is high, the cost of the raw material is low, the soybean meal-based adhesive is easy to apply, and the pre-pressing performance is good.
Description
Technical field
The invention relates to the preparation method of dregs of beans base adhesive, the particularly combination of multiple crosslinking agent and application in preparation process.
Background technology
Dregs of beans is the residuum of grease industry, and its abundant, renewable, safety and environmental protection in source is used it for the preparation sizing agent and can be realized the part substitution of resources, has higher economic benefit and environmental benefit.
China's wood-based plate output 2.53 billion cubic meters in 2011 consume sizing agent and reach more than 1,000 ten thousand tons, a large amount of fossil feedstock of annual use.Present China based Wood Adhesives raw material is mainly take phenol, urea, formaldehyde as main, and is high to the petrochemical material dependency degree, and burst size of methanal is higher.
The future thrust low-cost, that the environment-friendly biomass base adhesive becomes the based Wood Adhesives industry.Therefore research and development based on the low-cost environment-friendly based Wood Adhesives of dregs of beans albumen, will overcome the traditional timber sizing agent problem high to the petrochemical material dependency degree, promote China's wood-based plate industrial upgrading.
But soy protein adhesives is used for plywood making industry, and in its coating, precompressed performance, the hygrometric state bonding strength aspect of gained glued board is not ideal enough.Therefore, people adopt the whole bag of tricks to carry out modification, as composite modified in blend, chemical reaction modification etc.
In the prior art, soybean segregation albumen is generally adopted in the preparation of soybean adhesive, its, causes production cost higher; Employing and phenolic glue, urea-formaldehyde glue carry out in composite modified method, cause and still have free formaldehyde in the soya-based based Wood Adhesives; Commercially available soybean adhesive, its in use needs higher hot pressing condition, reaches 140 degree as hot pressing temperature, and pressure 1.6MPa causes energy-output ratio large, has increased the production cost of artificial board enterprise; Soybean adhesive, its also exists viscosity high, and the defectives such as coating and precompressed poor performance remain to be further improved.
Summary of the invention
The present invention is directed to the problem that prior art exists, proposes a kind of dregs of beans protein-based sizing agent and preparation method thereof, have that preparation technology is simple, environmental protection, easy to use, the glued board of preparation glues together intensity and reaches the characteristics such as GB II class plate requires.
The present invention is achieved by the following technical solutions: a kind of dregs of beans protein-based sizing agent, and raw material is composed as follows by mass parts:
20～30 parts, soybean meal powder,
74～58 parts, water,
5～10 parts of multiple crosslinking agents,
Multiple crosslinking agent used is any several mixture in urea, polyvinyl alcohol, isocyanates, acylamide polymer.
Described soybean meal powder is defatted soybean meal, and granularity is 50～400 orders.
If the pH value not between 3～10, also is added with pH adjusting agent and regulates, described pH adjusting agent is the mixture of any one or any two kinds in phosphoric acid, hydrochloric acid or oxalic acid.
Described acylamide polymer is any one in anion-polyacrylamide, cationic polyacrylamide, Polyamide-Polyamsne-Epichlorohydrin and amphiprotic polyacrylamide.
Described isocyanates is any one in '-diphenylmethane diisocyanate, tolylene diisocyanate, hexamethylene diisocyanate and xylylene diisocyanate.
The pH value is 3～10.
Solids content is at 20～40%wt.
Prepare the method for described dregs of beans protein-based sizing agent, the soybean meal powder is added to the water, the pH value is as directly, adding multiple crosslinking agent to stir and get final product after 30～90 minutes in 45 ℃～85 ℃ reactions between 3～10.
If the pH value is not adding pH value conditioning agent to be adjusted between 3～10 between 3～10.
Beneficial effect:
1, reduce the production cost of soya-based sizing agent: the soybean meal powder of employing is just through the commercially available defatted soybean meal that simply pulverizes and sieves or the glue mill is processed, and price is starkly lower than soybean segregation albumen; The compacting glued board is temperature required all to be complementary with existing industrial production with pressure, has saved energy consumption, has reduced cost;
2, two kinds or any two or more combination properties-correcting agent wherein such as employing urea, polyvinyl alcohol, isocyanates, amide substance, guaranteeing under enough bonding strengths, can also solve to add the problem that the viscosity that causes after linking agent is large, be coated with difficulty.
Embodiment
The invention will be further described below in conjunction with embodiment.
In the preparation process of above-mentioned dregs of beans protein-based sizing agent, raw materials usedly be commercially available, dregs of beans provides for Nan Jingwang reaches feed factory.
Dregs of beans protein-based sizing agent of the present invention is take commercially available defatted soybean meal as raw material, add multiple crosslinking agent after acid and heat treated, the rear discharging that stirs, multiple crosslinking agent used is any several mixture in urea, polyvinyl alcohol, isocyanates, amide substance;
Described dregs of beans dietary protein origin is in defatted soybean meal.
Described pH adjusting agent is a kind of or wherein combination of two kinds of phosphoric acid, hydrochloric acid or oxalic acid.
