Problems solved by technology

Latex-type rubber pressure-sensitive adhesives do not need to use organic solvents during the preparation process, and are environmentally friendly products. However, compared with solvent-type rubber pressure-sensitive adhesives, their initial adhesion and peel strength are weaker, and the laminate is prone to fogging. These defects limit the scope of application of latex rubber pressure sensitive adhesives

Abstract

The invention relates to the technical field of pressure-sensitive adhesives, in particular to an environment-friendly pressure-sensitive adhesive with a good bonding effect and a preparation method of the environment-friendly pressure-sensitive adhesive. The rubber composition comprises main rubber, blended rubber, a reinforcing agent, a tackifier, a grafting agent and a cross-linking agent, according to the environment-friendly pressure-sensitive adhesive with the good bonding effect and the preparation method of the environment-friendly pressure-sensitive adhesive with the good bonding effect, the natural rubber with the environment-friendly property is added as a main body, the blended rubber and the reinforcing agent are matched, the reinforcing agent is added, and therefore the environment-friendly pressure-sensitive adhesive with the good bonding effect is obtained. The paraffin is modified by the m-pentadiene petroleum resin, so that the water resistance and the adhesive capacity are improved; through blending modification with butadiene styrene rubber, the anti-aging performance and heat resistance of the pressure-sensitive adhesive can be improved, complementation with natural rubber is formed, and the modified butadiene styrene rubber can further improve the peel strength when having the effects.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, in particular to an environment-friendly pressure-sensitive adhesive with good bonding effect and a preparation method thereof. Background technique [0002] At present, rubber pressure-sensitive adhesives can be divided into solvent-type rubber pressure-sensitive adhesives and emulsion-type rubber pressure-sensitive adhesives. Solvent-type rubber pressure-sensitive adhesives will emit a large amount of volatile organic compounds during the coating process, which not only causes serious pollution to the environment, Also cause bigger harm to user's physical and mental health. Existing studies have shown that VOC can cause imbalance in the immune level of the human body, affect the function of the central nervous system, and cause symptoms such as dizziness, headache, drowsiness, weakness, and chest tightness. It may also affect the digestive system, causing symptoms such as l...
