specific Embodiment approach 1
[0009] Specific embodiment one: a kind of phenolic resin hybrid phosphate adhesive of this embodiment is made by aluminum dihydrogen phosphate solution, curing agent and phenolic resin solution, and the volume ratio of described phenolic resin solution and aluminum dihydrogen phosphate solution is: 0.1-0.5:1, the mass volume ratio of curing agent to aluminum dihydrogen phosphate solution is 1-3g:1mL.
[0010] The phenolic resin hybrid phosphate adhesive of this embodiment has a high temperature resistance up to 1300°C. The phenolic resin is used to toughen the phosphate system, which overcomes the problem of incompatibility between the phenolic resin and the phosphate system. At high temperatures, the phenolic resin can be mixed with phosphoric acid. The salt is sintered together to increase the strength of the system. At 1300°C, the bonding strength is 0.9MPa~1.6MPa, which solves the shortcomings of low bonding strength and high brittleness of phosphate adhesives in the prior ...
specific Embodiment approach 2
[0011] Specific embodiment two: the preparation method of a kind of phenolic resin hybrid phosphate adhesive of the present embodiment is to carry out as follows: one, be 1: 1.1~1.2 by weighing phenol and formaldehyde by the mass ratio of phenol and formaldehyde and add to In the reactor, add the catalyst, and stir at a speed of 300-600r / min for 10min-30min to form a mixed solution; wherein the mass percentage concentration of phenol is ≥99.6%, the mass percentage concentration of formaldehyde is ≥36%, and the amount of catalyst added is the mass of formaldehyde 1% to 1.5% of 1% to 1.5%; 2. Heat up the mixed solution in step 1 to 80°C to 100°C and keep it for 4h to 6h. 5 Under the condition of Pa, underpressure distillation dehydration, stop vacuum distillation when mixed solution temperature is 110 ℃~120 ℃, obtain phenolic resin; 3, then add the ethanol that mass percentage concentration is 99.7% in the phenolic resin that step 2 obtains, prepare The mass percent concentratio...
specific Embodiment approach 3
[0013] Specific embodiment three: the preparation method of a kind of phenolic resin hybrid phosphate adhesive of the present embodiment is to carry out as follows: one, get the phenol 115g that mass percentage concentration is 99.8%, the mass percentage concentration is 36.5% formaldehyde 135g, And add it into the reactor, then add 1.15g of sodium hydroxide, stir at a speed of 400r / min for 20min to form a mixed solution; 2. Heat up the mixed solution in step 1 to 90°C and keep it for 5h, then drop it to 25°C , at a vacuum of 1.01×10 5 Under the condition of Pa, underpressure distillation dehydration, stop vacuum distillation when mixed solution temperature rises to 100 ℃; Three, then add mass percent concentration to the mixed solution in step 2 and be the ethanol of 99.7%, be mixed with the mass percent concentration of phenolic resin 70% phenolic resin solution, ready for use; 4. Add 100 mL of 85% phosphoric acid solution and 45 g of aluminum hydroxide solid powder into the...
