Embodiment 1

[0025] Add 54 parts of natural rubber latex to a nitrogen-protected reactor and heat up to 60°C while stirring, and start adding 6 parts of anti-aging agent composite emulsion (composed of 97% by weight of 4,4-bis(2,2-dimethylbenzyl) Diphenylamine and 3% by weight of epoxidized soybean oil), 10 parts of acrylic resin emulsion (commercially available product) with a glass transition temperature of 60°C, 30 parts of fully hydrogenated C5, C9 copolymerized petroleum resin emulsion, and then cooled to room temperature, with ammonia water After adjusting the pH value to 8-9, filter to obtain the water-based pressure-sensitive adhesive.

Embodiment 2

[0027] In the nitrogen-protected reactor, add 70 parts of nitrile latex and heat up to 55 ° C while stirring, start to add 5 parts of anti-aging agent composite emulsion (by 92% by weight of N-phenyl-N'-isopropyl-p-phenylene) Diamine, 3% by weight of machine oil and 5% naphthenic oil), 5 parts of acrylic resin emulsion with a glass transition temperature of 40°C, 20 parts of terpene resin emulsion, then cooled to room temperature, and adjusted to pH 8 with ammonia water After -9, filter to obtain the water-based pressure-sensitive adhesive.

Embodiment 3

[0029] Add 60 parts of styrene-butadiene latex to the reactor under nitrogen protection and heat up to about 62 ° C while stirring, start to add 4 parts of anti-aging agent composite emulsion (by 50% by weight of N-phenyl-β-naphthylamine, 45% by weight N-phenyl-N'-isopropyl-p-phenylenediamine and 5% by weight of stearic acid) 5 parts of acrylic resin emulsion with a glass transition temperature of 80 ° C, 21 parts of carboxylated styrene-butadiene latex, 10 parts of terpene The resin emulsion is then cooled to room temperature, adjusted to pH 8-9 with ammonia water, and filtered to obtain the water-based pressure-sensitive adhesive.

Abstract

The invention provides an aqueous pressure-sensitive adhesive, which comprises the following components in percentage by weight: 54-81% of rubber latex, 5-10% of acrylic resin emulsion, 10-30% of tackifying resin emulsion and 4-6% of anti-aging agent emulsion, wherein the weight percentages of the various components are dry basis weights of the components. The invention further provides a preparation method of the aqueous pressure-sensitive adhesive. When being applied to surface protective paper, the aqueous pressure-sensitive adhesive provided by the invention is capable of protecting surfaces of products, such as acrylic plates, polycarbonate plastic plates, polystyrene plates, polyvinyl chloride plates, glass, marble and wood furniture decorative plates, under the ultra-low peeling strength, and avoiding the conditions, such as foaming, edge warping, and residual after tearing.

Description

technical field [0001] The invention relates to a water-based pressure-sensitive adhesive and a preparation method thereof, more specifically, the invention relates to a water-based pressure-sensitive adhesive for surface protection paper and a preparation method thereof. Background technique [0002] Surface protection paper can be applied to protect the product surface of acrylic board, polycarbonate plastic board, polystyrene board, polyvinyl chloride board, glass, marble, wood furniture decoration board, etc. When using the surface protection paper, it is required to be able to stick flat, no warping, no foaming, no wrinkling, etc. It is also required to be suitable for subsequent processing, such as laser cutting and other operations, and it is also required to be easily Peel off without any residue and hard to tear. [0003] However, the surface protection paper in the prior art is prone to problems of blistering, edge warping and residue after tearing due to the adhe...
