Abstract
The invention discloses a biomass aldehyde-free adhesive for plywood. The biomass aldehyde-free adhesive is characterized by being prepared from the following ingredients in parts by weight: 770 parts of deionized water, 110 parts of polyvinyl alcohol, 45-55 parts of oxidized starch, 4.5-6 parts of liquid alkali, 25 parts of kaolin, 45 parts of calcium carbonate, 0.15 part of sodium tripolyphosphate and 6-8 parts of glycol. The biomass aldehyde-free adhesive for plywood, disclosed by the invention, is absolutely free of the toxic properties of urea-aldehyde adhesives and phenol-aldehyde adhesives and is high in adhesive strength and good in water resistance; and compared with the prior art, the biomass aldehyde-free adhesive has the advantages that the biomass aldehyde-free adhesive is non-toxic, harmless, green and environmental-friendly, the price is slightly higher than that of the urea-aldehyde adhesives and is lower than that of the phenol-aldehyde adhesives, the low-price and fine-quality performance is good, the market demand is extremely high, and the formula is simple and complete. According to the biomass aldehyde-free adhesive disclosed by the invention, the production raw materials are easily obtained, the process is simple, and the operation is convenient, so that the biomass aldehyde-free adhesive is applicable to industrial large-scale production.
Description
Technical field
What the present invention relates to is a kind of biomass aldehyde-free by wood tackiness agent, has also related to the manufacture craft of this kind tackiness agent.
Background technology
Progress along with society, the raising of people's living standard, the each side such as various office accommodationss, furniture, decoration, building use the demand of sheet material, timber, bamboo wood more and more, use maximum then several glued boards, no matter be three layers, five layers, seven layers, nine layers and even infinite layers, as long as the user has requirement, producer can both produce.Nature, the production of glued board be unable to do without plywood glue.In order to reduce cost, increase competitive power, even the most urine aldehyde glue that use of plywood production producer in order to improve the grade, also only are to use phenolic glue.No matter urinate aldehyde glue, phenolic glue, the formaldehyde that all contains hazardous substance, formaldehyde are carcinogenic substances, to human, very big to environmental hazard.No matter how manufacturer publicizes and by means such as seizure, chelatings the residual formaldehyde of urine aldehyde glue, phenolic glue has been reduced to meet in national standard 1 ‰ scopes, but root problem is: still having used formaldehyde in the glue of production is a undisputable fact, let alone how to say that aldehyde is still arranged! Having aldehyde just toxic, only is exactly that the murder by poisoning degree is had any different.Soybean glue is exactly formaldehydeless plywood glue on the market, and the advantage of this kind glue is: without aldehyde, nontoxic, harmless, and also easy to use.But its storage property is unstable, and viscosity changes greatly, and responsive to envrionment temperature, high temperature is very easily mouldy, corrupt, rotten, smelly; And bonding strength is lower, and poor water resistance, defective are also fairly obvious.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of biomass aldehyde-free by wood tackiness agent, nontoxic, harmless, the environmental protection of this kind biomass aldehyde-free by wood tackiness agent, and bonding strength is high, water-tolerant.And without the defective of soybean glue.
The present invention also provides the manufacture craft of this tackiness agent.
Tackiness agent of the present invention adopts following technical scheme to realize:
A kind of biomass aldehyde-free by wood tackiness agent is characterized in that: the proportioning that comprises following ingredients weight parts consists of:
The present invention deals with problems and can also further take following innovative approach:
Also comprise 100 parts of tougheners.
Also comprise 1.5 parts of Antisepticize and mildew preventives.
Tackiness agent of the present invention can be taked following manufacture craft:
A kind of manufacture craft of biomass aldehyde-free by wood tackiness agent comprises following processing step:
1, in reactor, adds 670 parts of deionized waters; Add again polyvinyl alcohol; Being warming up to 90 degree fully dissolves polyvinyl alcohol; After polyvinyl alcohol fully dissolves, again cooling;
2, be cooled to 60 when spending, drop into the dispersion liquid that is formed by 50 parts of deionized waters, Sumstar 190s; Add liquid caustic soda and regulate pH value to 7.5-8, then be warming up to 90 degree, be incubated 30-40 minute, carry out the gelatinization reaction;
3, drop into auxiliary agent A solution, drop into again the dispersion liquid that formed by 50 parts of deionized waters, tripoly phosphate sodium STPP, kaolin, calcium carbonate, after 80 to 85 degree insulation half an hour, lower the temperature;
4, be cooled to 50 degree, add ethylene glycol; Be cooled to 40 degree when following, filtration discharging, packing.
Compared with prior art, the present invention has following beneficial effect:
Biomass aldehyde-free by wood tackiness agent of the present invention, absolutely not urinate the toxic of aldehyde glue, phenolic glue, bonding strength is high, water-tolerant, compared with prior art, nontoxic, environmental protection, price is a little more than urine aldehyde glue, be lower than phenolic glue, good and cheap performance is good, and market demand is very big, and prescription is simply complete.
Manufacture craft raw material sources of the present invention are easy, and technique is simple, and is easy to operate, are suitable for the large production application of industry.
