Abstract
The invention discloses a novel ecological non-toxic waterproof flame-retardant bonding agent for straw artificial board production. The bonding agent is prepared from the following ingredients in proportion by weight: 10 to 35 percent of bonding agents, 60 to 90 percent of curing agents, 1 to 5 percent of modifying agents and 3 to 10 percent of phenolic resin. Double ingredients of main bonding agents and the curing agents are used; the certain modifying agents are added so as to enhance the bonding force of the bonding agent and improve the anti-bending intensity and anti-impact and waterproof performance. The bonding agent breaks through the industry barrier that isocyanate is necessary for the production of a straw artificial board at present. The production cost is reduced; the product quality is improved, so that the product has the characteristics of non-toxicity, waterproof performance, flame-retardant performance and the like. All equipment and processes for producing the straw artificial board both at home and abroad adopt a hot pressing process for production, the pollution is great, and the production cost is increased. When the novel special non-toxic waterproof flame-retardant special bonding agent for the straw artificial board is used, a cold pressing process is used for production, and the problem of the complicated hot pressing production process is fundamentally solved; the production efficiency is greatly improved. In addition, the produced product has the advantages of non-toxicity, waterproof performance, flame-retardant performance and an ecological and environment-friendly effect; a new crop straw integral utilization and farmer yield increase path is opened up.
Description
Technical field
The present invention relates to wood-based plate and manufacture field, be specially novel straw wood-based plate tackiness agent and production method thereof.
Background technology
China is a large agricultural country, produces 800000000 tons of agricultural crop straws per year.In timber shortage, under the situation that agricultural straw resource is wasted and wood-based plate is in great demand, substitute timber with agricultural crop straw and manufacture wood-based plate, be the alternative of an environmental protection, save a large amount of forest reserves.
Environment-protective stalk wood-based plate is as ecology, environmental protection, new energy-saving material, and not only product performance are excellent, nontoxic, not so waterproof fireproofing can reach A level.And the pollution of mass peasants' crop straw burning to environment can be eliminated, accomplish the comprehensive utilization of resource.Too increase farmers' income simultaneously, meet conservation-minded society, the requirement of recycling economy and Sustainable development.
Chemical composition mainly Mierocrystalline cellulose and the lignin of stalk, surface is containing waxy substance and silicon matter, interfacial activity is very poor, be difficult to realize effective bonding with traditional tackiness agent, artificial board of straw factory of current China mostly uses import tackiness agent, and import tackiness agent is expensive, 12000 yuans per ton, and employing heat pressing process, production cost is high, and complex process has pollution.
Summary of the invention
In order to overcome because stalk surface is containing the material such as wax and silicon in above-mentioned prior art, general glue is difficult to the problem bonded.The invention provides one and have employed tackiness agent and solidifying agent two-pack, add properties-correcting agent again simultaneously, to strengthen the caking ability of product, break and produce novel straw wood-based plate tackiness agent and the production method thereof that artificial board of straw must use the monopolization of import glue at present
。Change production technique, reduce production cost.
The object of the present invention is achieved like this:
Novel straw wood-based plate tackiness agent, is characterized in that, comprises the material component of following weight ratio: tackiness agent: solidifying agent: properties-correcting agent: resol is 10-35:60-90:1-5:3-10;
Described solidifying agent is magnesium oxide, and its content is at more than 80%-90%, and active quantities is best at more than 60%-70%; Tackiness agent is magnesium chloride, and the content 90%-95% of magnesium chloride is best;
Described properties-correcting agent is redispersible latex powder or sodium cellulose glycolate (CMC);
The production method of described novel straw wood-based plate tackiness agent, comprises the following steps:
A, tackiness agent magnesium chloride is put into container, adding water according to weight ratio 1:5 stirs, and becomes liquefaction shape, stand-by; Strength of solution is 25-30%;
B, magnesium chloride liquid obtained for step a is put into solidifying agent magnesium oxide, then add properties-correcting agent redispersible latex powder or sodium cellulose glycolate (CMC) resol and fire retardant, stirring can become stalk board and produce adhesive specially;
Toughener, water-resisting agent, fire retardant and solidifying agent to be added, better effects if in c, described step b simultaneously.
positive beneficial effect:the invention solves the core technology that stalk board is produced, and product also ecological, environmental protective, nontoxic, waterproof and fire-retardant, fire prevention temperature can reach more than 800 DEG C.That at present unique production both at home and abroad meets material of construction that NFA general bureau specifies and the standard that furniture material A level is not fired.Artificial board of straw tackiness agent of the present invention, price per ton 1200 yuans, and adopt cold-press process to produce, reduce cost, decrease production technique and pollution.Be all at present adopt heat pressing process to produce artificial board of straw in the world, and artificial board of straw tackiness agent of the present invention, the product produced with its is nontoxic, can not reach A level do not fire level containing formaldehyde, waterproof, fire prevention.
