7. a kind of preparation according to claim 1 for using new type resin adhesive for container bottom board bamboo mat bamboo curtain splint dipping
Technique, which comprises the steps of:
S1, each component is weighed by above-mentioned composition, and by control errors within 1%；
S2, the polyurethane modified epoxy resin of the parts by weight and silicon carbide stirring are warming up to 40-60 degrees Celsius, reaction
120-200min obtains A phase mixture；
S3, the formaldehyde measured and A phase mixture are all put into reaction kettle, start blender, open steam valve heating
Heating, with sodium hydroxide tune reaction solution PH to 9.0-10, is added first urea and melamine, after mixing, obtains anti-
Liquid is answered, this batch of urea is the 58%-62% of urea total amount, this batch of melamine is the 60%-62% of total amount；
S3, after the completion of S2, carry out heating treatment, when reacting liquid temperature rises to 75-80 degrees Celsius, be added second batch urea,
This batch of urea is the 38%-42% of urea total amount, while continuing to heat up, and when reacting liquid temperature rises to 85-90 degrees Celsius, closes
Steam valve starts to keep the temperature, and soaking time 70-80 minutes, 91-94 degrees Celsius of holding temperature；
S4, reaction solution pH value is adjusted, specific as follows:
Reacting liquid temperature is adjusted to 80-85 DEG C, with formic acid tune reaction solution PH to 5.2-5.8, is reacted 20-30 minutes；
With formic acid tune reaction solution PH to 5.0-5.5, react 15-20 minutes；
Again with formic acid tune reaction solution pH value to 4.1-4.5, the reaction was continued, and constantly takes a sample test reaction fluid viscosity, applies 4 when 25 DEG C
Cup number of seconds is until 28-30 seconds；
After S5, viscosity are up to standard, with sodium hydroxide tune reaction solution pH value to 8.5-9.0, and 85-90 DEG C of reacting liquid temperature are controlled, added
Enter second batch melamine, this batch of melamine is the 38%-40% of total amount, and checking and adjusting PH is 8.5-9.0, reaction solution temperature
83-85 DEG C of degree, the reaction was continued 20-25 minutes；
S6, inspection simultaneously adjust PH as 7.0-7.5, whole triethanolamine and phthalic anhydride are added, reacting liquid temperature is controlled in 75-80
DEG C, the reaction was continued 20-30 minutes；
S7, reaction solution is made to cool down, checking and adjusting PH is that 7.0-7.5 obtains this hair when reacting liquid temperature is down to 35-40 DEG C
The bright adhesive.
8. the preparation work according to claim 7 for using new type resin adhesive for container bottom board bamboo mat bamboo curtain splint dipping
Skill, which is characterized in that the mixed aid is specially the mixture of dispersing agent, defoaming agent, curing agent and anti-aging agent, and point
Powder, defoaming agent, curing agent and anti-aging agent molal weight ratio be 1:0.2:1:0.5.
