Abstract

The invention discloses a bamboo fiber nano-silver antibacterial mildewproof synergistic mildewproof plate adhesive which is prepared from, by weight, 100-110 parts of corn protein, 8-9 parts of acrylamide, 2-2.5 parts of maleic anhydride, 8-9 parts of ammonium persulfate, proper amounts of sodium hydroxide of 40wt% in concentration and distilled water, 50-55 parts of water glass of 2.8 in modulus, 9-10.5 parts of polyvinyl alcohol, 2-3 parts of tetraethyl orthosilicate, 1.7-2 parts of sulfamic acid, 1-1.2 parts of silane coupling agent kh550, 0.8-1 part of potassium sorbate, 8-9 parts of nano montmorillonite, 5-6 parts of nano bamboo fiber, 1.4-1.5 parts of silver nitrate, 2-2.5 parts of chitosan, a proper amount of acetic acid of 35wt% in concentration and 10-11 parts of hydrogen peroxide solution of 30wt% in concentration. The adhesive is easy to brush, raw materials used are environment-friendly and nontoxic, the adhesive can be used for bonding mildewproof plates and has excellent moisture, waterproof and mildewproof performance.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a bamboo fiber nano-silver antibacterial, anti-mildew and synergistic anti-mildew board adhesive. Background technique [0002] Zein is a kind of renewable and biodegradable natural plant protein, which has the characteristics of low cost, convenient processing and no irritating smell. Because corn protein is insoluble in water and lacks essential amino acids such as lysine and tryptophan, it has low nutritional value and is rarely used in food raw materials. At present, except for a few used as low-quality feed protein for sale, many factories have not Direct discharge for any use has caused a great waste of resources and also caused harm to the environment. Now, people use zein in tissue engineering and medicine, but the application of zein in adhesives is less, so the market potential of developing zein, an environmentally friendly adhesive, is huge. [0003] In the articl...
