Embodiment 1
[0035] Embodiment 1: 200kg of water, EVA emulsion Celanese cp14950Kg, sodium acrylamido sulfonate 1kg, 1% sodiumbicarbonate 50Kg, 1%Kps40Kg, VAc90Kg, GMA22Kg, 2-EHA6Kg, appropriate amount of pH regulator, residual single treatment agent 0.5kg, additives 20kg, hpmc 10kg;
[0036] The production process is as follows: first add water and EVA emulsion into the reaction kettle, raise the temperature to 85°C, add reactive emulsifier and pH buffer, stir for 20 minutes until uniform and free of bubbles, then add initiator and monomers VAc, GMA and 2-EHA, react for 5 hours, then heat up to 90°C for 1.5 hours, then cool down to 63°C, add pH regulator to adjust pH to 6, add additives, residue treatment agent, viscosity regulator and stir for 60 Minutes until uniform, then after cooling down to 25°C, filter and pack the finished product.
Embodiment 2
[0037] Embodiment 2: 250kg of water, EVA emulsion Celanese cp14935Kg, sodium acrylamidosulfonate 1.5kg, 1% sodium bicarbonate 80Kg, 1%Kps70Kg, VAc120Kg, GMA26Kg, 2-EHA13Kg, appropriate amount of pH regulator, residual single treatment Agent 1.0kg, auxiliary agent 15kg, hpmc 6kg. The production process can be made according to the method described in Example 1.
Embodiment 3
[0038] Embodiment 3: 270kg of water, EVA emulsion Celanese cp14958Kg, sodium acrylamidosulfonate 2.0kg, 1% sodium bicarbonate 95Kg, 1%Kps90Kg, VAc140Kg, GMA29Kg, 2-EHA10Kg, appropriate amount of pH regulator, residual single treatment Agent 2.1kg, auxiliary agent 30kg, hpmc 20kg. The production process can be made according to the method described in Example 1.
[0039] The performance test indicators of the high-strength antifreeze one-component panel glue prepared in Examples 1-3 refer to relevant standards (test environment: temperature: 25°C, humidity: 70%) as shown in Table 1:

technical field [0001] The invention belongs to the technical field of adhesive manufacture, and in particular relates to a high-strength antifreeze one-component glue and a preparation method thereof. Background technique [0002] According to the characteristics of wood material, the characteristics of large deformation due to absorption and loss of water. A glue that can penetrate into wood well, has excellent film formation and strong cohesion, especially can form a good chemical bond with the characteristic reactive groups of wood fibers, and solve the problem of easy cracking of wood panels. ; [0003] In China, Deng Chongyang and Ma Peihua "Research and Development of One-Component Laminate Emulsion" reported that polyvinyl alcohol (PVA) acetal solution was added to a solution of TMP-TDI adduct blocked by aniline to make a one-component glue. Board glue; Zheng Weizhou and Zhang Cheng used polyvinyl alcohol as a protective colloid, and then used vinyl monomers to pol...
