Abstract
The invention discloses a preparation method of wood adhesive which is prepared by 10-70 portions of modified soybean flour solution and 90-130 portions of phenol formaldehyde adhesive (E1 level in market). The preparation method comprises the following steps: preparing 20-30 percent of solution by more than 100 mu of defatted soybean flour condensate, adjusting the pH value to be 4.5-5.5; respectively adding 0.1-0.5 percent of cellulose and 0.01-0.5 percent of pectase; hydrolyzing the solution added with the cellulose and the pectase for 30-120 minutes at the temperature of 48-52 DEG C; adjusting the pH value to be 7.0-10; hydrolyzing the solution added with the cellulose and the pectase for 30-120 minutes by 0.01-0.5 percent of neutral or alkali protease; adjusting the pH value to be 7.5-10.5, and mixing the solution added with the cellulose and the pectase with metlbond according to the proportion of 10-70 portions so as to obtain the wood adhesive. The release amount of formaldehyde achieves the E0 level of European standard. The wood adhesive has lower viscocity which can achieve less than 30s by mixing with the low-viscocity phenolic resin, thereby meeting the use requirements of spraying and coating.
Description
Technical field
The present invention relates to a kind of tackiness agent, relate in particular to a kind of wood adhesive and preparation method thereof.
Background technology
The kind of wood adhesive is a lot, and artificial liner enterprise is mainly used sheet materials such as tackiness agent producd fibers plate, glued board, shaving board such as Precondensed UreaFormaldehyde Resin, resol.The cohesive strength and the water resisting property of the sheet material that resol is produced are better, can be in order to build products such as house that adhesive property has relatively high expectations, compartment board.The burst size of methanal of the sheet material of common resol manufacturing can reach the E1 level, and the burst size of methanal of modified phenolic tackiness agent can reach European standard E0 level, and price is also higher.At the beginning of the eighties of last century, the rubber made from soybean cake stick is widely used in the production of wood-based plate, but is substituted by good, the cheap Precondensed UreaFormaldehyde Resin of water resisting property afterwards, because the non-renewable and burst size of methanal of petroleum base tackiness agent is higher, brings very big harm to human body.
Summary of the invention
The objective of the invention is to provide the preparation method of wood adhesive for fear of above-mentioned deficiency.
The object of the present invention is achieved like this:
The preparation method of wood adhesive is by the soybean bean powder aqueous solution: 10-70 part, phenolic aldehyde (commercially available E1 level): 90-30 part, cellulase: 0.1-0.5%, polygalacturonase: 0.1-0.5%, neutrality or Sumizyme MP: 0.01-0.5% etc. is that raw material production is made, and it is characterized in that:
Step 1: configuration concentration is the skimmed soy beans bean powder aqueous solution of 20-30%, be heated to 50 ± 2 ℃, be mineral acid or organic acid (example hydrochloric acid, phosphoric acid, lactic acid etc.) the adjusting pH value 4.5-5.5 of 5-30% then with concentration, add 0-0.5% cellulase and polygalacturonase more respectively, hydrolysis 30-120 minute;
Step 2: with alkali concn is that 0-30% (as sodium hydroxide, potassium hydroxide, ammoniacal liquor etc.) regulates the pH value for more than the neutrality, and neutrality or Sumizyme MP with 0.01-0.5% are hydrolyzed, hydrolysis time position 30-120 minute;
Step 3: regulate bean powder pH value of solution 9.5-11 with above-mentioned alkali;
Step 4: press bean powder solution: phenolic aldehyde, the 10-70:90-30 mixed is even.
The granularity of bean powder raw material is the 90-200 order.
The invention has the beneficial effects as follows: the artificial board burst size of methanal of production of the present invention reaches European standard E0 level level; Viscosity is lower, mixes with low-viscosity resol, and viscosity can reach below 30 seconds, can satisfy the service requirements of spraying gluing.
