Abstract

The invention discloses a nano SiO2 modified water-soluble acrylate pressure-sensitive adhesive and a preparation method thereof, and particularly relates to the field of pressure-sensitive adhesives. The adhesive is prepared from the following raw materials in parts by weight: 4 to 6 parts of acrylic acid, 3 to 5 parts of adipic acid, 4 to 6 parts of terephthalic acid, 10 to 14 parts of isophthalic acid, 40 to 50 parts of hydroxyethyl acrylate, 20 to 30 parts of methyl methacrylate, 10 to 20 parts of ethyl acrylate, 2 to 4 parts of 2-ethylhexyl acrylate, 6 to 8 parts of pentanediol, 8 to 12 parts of N, N-dimethylethanolamine, 1 to 2 parts of silane coupling agent A-151 and 0.5 to 1.5 parts of nano SiO2. A silane coupling agent A-151 is used for carrying out surface treatment on glass fibers of nano SiO2, so that the water resistance of the glass fibers is improved, the glass fibers can be more quickly bonded with an adhered object, and the defect that an existing water-soluble acrylate pressure-sensitive adhesive is relatively slow in drying rate is greatly overcome.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, more specifically, the invention relates to a nano-SiO 2 Modified water-soluble acrylate pressure-sensitive adhesive and its preparation method. Background technique [0002] Acrylic pressure-sensitive adhesives are currently the most widely used pressure-sensitive adhesives, which are copolymers of acrylate monomers and other vinyl monomers. Compared with other pressure-sensitive adhesives, it has the following characteristics: excellent weather resistance and heat resistance without adding anti-aging agent; no phase separation and migration phenomenon, good transparency and good oil resistance. [0003] With people's increasing emphasis on environmental protection, safety and energy saving, and the continuous expansion of the application of pressure-sensitive adhesives, it has become a trend for pressure-sensitive adhesives to develop in the direction of low pollution, ene...
