Problems solved by technology

Starch is the second largest renewable resource in nature. It is cheap, natural and non-toxic. The preparation of starch is environmentally friendly and does not produce three wastes. It is a renewable natural polymer material, and its production process is simple and requires less investment in equipment. Small in size, low in production cost, wide in sources and uses, it has been widely used in the bonding of corrugated cardboard, packaging cartons, etc., and has become one of the most promising adhesive varieties. Poor performance, difficulty in sizing, poor water resistance, low bonding strength, etc., resulting in great restrictions on its application

Embodiment 1

[0010] 1) 1) First weigh 5 parts by weight of SSZ-13 molecular sieve nanoparticles and slowly add it to 25 parts by weight of an acidic reagent with a weight percentage of 56%. After magnetic stirring for 30 minutes, add 12 parts by weight of deionized water and 2 parts of Fe2O3 powder Mix, put the sample into the centrifuge, centrifuge at 3800r / min for 6~8min, pour off the supernatant, then add 12 parts by weight of deionized water, put it in the centrifuge and centrifuge for 6~8min, repeat the above operation for 4 After ~5 times, put the sample into a dialysis bag and soak it in distilled water, change the water 3~4 times a day, dialyze for 2~3 days, let stand at room temperature for more than 1h, calcinate at 600°C for 5h, then filter, wash and dry to get Modified Fe-SSZ-13 molecular sieve nanoparticles for standby;

[0011] 2) Add 35 parts by weight of cornstarch and 50 parts by weight of 20% ethanol aqueous solution into a 500ml two-necked microwave flask, stir and shake...

Embodiment 2

[0016] It is exactly the same as Example 1, except that 2 parts by weight of modified Fe-SSZ-13 molecular sieve nanoparticles, 0.35 parts by weight of NaClO, and 28 parts by weight of furfural resin are added.

Embodiment 3

[0018] It is exactly the same as Example 1, except that 6 parts by weight of modified Fe-SSZ-13 molecular sieve nanoparticles, 1.05 parts by weight of NaClO, and 42 parts by weight of furfural resin are added.

Abstract

The invention discloses a preparation method of a compound modified starch adhesive. Through the preparation method of the compound modified starch adhesive, modified Fe-SSZ-13 molecular sieve nanoparticles, furfural resin, corn starch and nitrile rubber are used as raw materials. The method comprises the following preparation processes: adding the Fe-SSZ-13 molecular sieve nanoparticles, adding an albumen powder / nitrile rubber / natural rubber compound material, and preparing the compound modified starch adhesive through methods of oxidation modification method, physical compounding and the like. The compound modified starch adhesive prepared by the method has the advantages of stable chemical property, low consumption, easily available raw materials, low production cost, high water resistance, high shearing strength and good popularization and application value.

Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive for wood. Background technique [0002] With the continuous enhancement of people's awareness of environmental protection, biomass wood adhesives have become an important development trend in the field of wood adhesives. Starch adhesive is a natural environment-friendly adhesive prepared with natural starch (such as corn starch, wheat starch, potato starch, rice starch, tapioca starch and sweet potato starch, etc.) Adhesive substance. Starch is the second largest renewable resource in nature. It is cheap, natural and non-toxic. The preparation of starch is environmentally friendly and does not produce three wastes. It is a renewable natural polymer material, and its production process is simple and requires less investment in equipment. Small in size, low in production cost, wide in sources and uses, it has been widely used in the bonding of corrugated cardboard, packaging cartons, et...
