Abstract
The water soluble phenol-formaldehyde resin adhesive consists of water soluble phenol-formaldehyde resin and acetal in the weight ratio of 100 to 5-30, and the water soluble phenol-formaldehyde resin consists of phenol and formaldehyde in the weight ratio of 100 to 115-170, and the weight ratio of monovalent phenol to bivalent phenol in phenol is 100 to 5-30.
Description
The present invention relates to tackiness agent, particularly be applied to the adhesive made of synthetic resin that coated abrasive tool is used.
At present, when producing coated abrasive tool, the good direct performance quality that influences coated abrasive tool of tackiness agent performance, it is gluing to be that high level coated abrasive tool that the flexible abrasive material of the critical material that influences the coated abrasive tool quality grade, particularly high level is made more needs special-purpose water-soluble phenolic resin adhesive.
The purpose of this invention is to provide a kind of water-soluble phenolic resin adhesive, it is good to have tackiness, the performance that extent of dilution is good.
Technical scheme of the present invention is, it is made up of water soluble phenol resin and acetal, the weight ratio that it is characterized in that them is a water soluble phenol resin: acetal=100: 5-30, wherein the weight ratio of phenol in the water soluble phenol resin and formaldehyde is 100: 115-170.And the weight ratio of unit price phenol in the phenol and divalent phenol is 100: 5-30.
Used its key technical indexes of water-soluble phenolic resin adhesive of high level flexible abrasive material is as follows:
1, B-time (branch) (120 ℃ ± 2 ℃) 6-10
2,135 ℃ volatile content % 68 ± 2
3, free phenol %≤4
4, pH value 8.5-9.0
5, thinning ratio 〉=1.1
6, viscosity (CPS/25 ℃) 600-4000
The weight ratio of water soluble phenol resin and acetal is 100 in water-soluble phenolic resin adhesive: 5-30 wherein: the weight of acetal is less than at 5 o'clock, tackiness agent fragility is excessive, viscosity is little, cracking easily behind the adhesive curing, when the content of acetal greater than 30, the viscosity of tackiness agent is big, and tackiness agent is soft excessively, and intensity is low behind the adhesive curing.The phenol in the composition water soluble phenol resin and the weight ratio of formaldehyde are 100: 115-170, wherein: formaldehyde weighs less than 115, made water soluble phenol resin molecular weight is excessive, after acetal mixes, the water-soluble phenolic resin adhesive dilutability of making significantly reduces, the inconvenience dilution, thinning ratio was less than 1: 1, when formaldehyde weight greater than 170 the time, the water soluble phenol resin molecular weight of making is less, and to make the viscosity of water-soluble phenolic resin adhesive very little with acetal, need not dilute, can't be coated with the base material tack is too poor in use.In the phenol component, the weight ratio of unit price phenol and divalent phenol is 100: 5-30, and wherein divalent phenol weighs less than 5, then too many with its side chain of water soluble phenol resin of making after formaldehyde mixes, molecular weight is little, and its production process is difficult to control, and the water-soluble phenolic resin adhesive viscosity of making is very little, flowability is very big, can't be coated with, when divalent phenol weight greater than 30, then few with its side chain of water soluble phenol resin of making after formaldehyde mixes, it is low to solidify the back cross-linking density, will obviously reduce bonding strength.
The present invention has good tackiness and reaches dilution property preferably, can reach the technical indicator of the used water-soluble phenolic resin adhesive of above-mentioned high level flexible abrasive material.
