Embodiment 1
[0026] A formaldehyde-free glue synthesized by chemical materials, the formulation of which is as follows: 50 parts of solution A and 50 parts of solution B.
[0027] The present invention also provides a preparation method for synthesizing formaldehyde-free glue from chemical materials, comprising the steps of:
[0028] S1, preparing solution A, using monomer EVA resin with a solid content of 45% to prepare the main resin liquid A;
[0029] S2, prepare solution B, utilize the C9 petroleum resin solid of 25% by mass and 75% ethanol solvent, mix and dissolve under normal temperature, mix and stir evenly, prepare accelerator B;
[0030] S3. Mix according to the ratio of 50 parts of solution A and 50 parts of solution B, wherein the temperature of pure water is 5°C, then put it into the reaction kettle, turn on the mixer, make it rotate at 40 rpm, and heat to Stirring at 36°C for 38 minutes yields an formaldehyde-free adhesive at pH 7.8.
