Description
Technical field
The present invention relates to stalk sheet material adhesive water-fast modifying agent field, specially stalk board water-fast modifying agent of inorganic adhesive and preparation method thereof.
Background technology
The demand of China's adhesive nearly ten years quickly increases, and average annual growth rate is about 20%, and wherein, sheet material sticks agent with three big glue kind phenolic aldehyde adhesives, urea-formaldehyde glue and melamine-formaldehyde resin adhesive yield is maximum, accounts for about the 40% of adhesive total output.But, global oil unbalanced supply problem is on the rise, the minimizing of petroleum reserves and rising steadily of oil price, and the production giving oil and " three-aldehyde glue " that chemical products are raw material brings lot of unstable factor, causes its production cost to increase, and development baffles.Simultaneously, three-aldehyde glue can discharge harmful free-phenol, formaldehyde when producing and use, baneful influence is brought to environment and masses' health, especially in interior decoration and Furniture panel, because the incomplete polycondensation of formaldehyde, solidification resin discharges free formaldehyde because of hydrolysis or decomposition, progressively distributes to surrounding and causes indoor environmental pollution.
Along with constantly strengthening of people's environmental consciousness and becoming better and approaching perfection day by day of national environmental protection regulation, more and more stricter with adhesive production and pertinent regulations and the standard used.Solve to poison, containing aldehyde adhesive and the low of goods thereof, the instant thing having become as relation human health.
Although currently also also exist many other without aldehyde wood materials (including fibrous material) adhesive product; such as poly-acetates, polyacrylate, polyvinyl alcohol, polyurethanes and epoxy resin adhesive etc.; but these adhesives are owing to price is compared with reasons such as high, synthesis technique is complicated, work progress toxicity is big, the demoulding is difficult, working life is short, no-aldehyde content of volatile organic compound height, it is difficult to cost performance requiring, obtaining scale in higher laminated product applies.So, the following outlet of wood-based panel industry adhesive necessarily development set aboundresources, raw material be easy to get, cheap, prepare and be used in high-performance environment protection type adhesive all over the body。
Inorganic adhesive is bonding for plant fiber material, is primarily present the problem that water resistance is the best, seriously constrains the extensive application of the inorganic adhesive including that silicate adhesive and Phosphate adhesive are representative.Developing a kind of water-fast modifying agent being applicable to inorganic wood material adhesive is direct way and the basic method solving this problem.
Summary of the invention
Technical problem solved by the invention is to provide stalk board water-fast modifying agent of inorganic adhesive and preparation method thereof, thus solves the problem in above-mentioned background technology.
