Abstract
The invention relates to a an adhesive applicable to adhesion among plastic, cloth and wood. The adhesive is prepared by compounding a plurality of raw materials and comprises water-based rubber latex, water-based starch latex, water-based vinyl polyurethane latex and water-based protein latex and further comprises a tackifier and an emolsifier. The water-based adhesive is applicable to the quickadhesion among the different plastics, cloth and wood, and has high adhesion strength and good adhesiveness at high-temperature and low temperature. The adhesive has the advantages that the adhesive is environmentally friendly and free from mildewing and the adhesion strength is not reduced for a long time. The adhesive can be widely applied to the field of package adhesion.
Description
technical field [0001] The invention relates to a water-based adhesive, in particular to an environmentally friendly, multi-component compound, which can be applied to the bonding between plastic-cloth-wood in packaging, has excellent viscosity and can achieve long-term bonding without degumming of adhesives. Background technique [0002] With the concept of protecting the environment and cherishing resources becoming more and more popular, more and more attention has been paid to the environmental friendly factors such as high solid content, solvent-free, water-based, light-curing adhesives and energy-saving technologies such as low-temperature curing and waste recycling. Continuously increase research and development efforts. In the field of flexible packaging, solvent-free adhesives and water-based adhesives are mainly used in the composite production of flexible packaging in developed countries in Europe and the United States. At present, more than 95% of flexible pa...
