Embodiment 1

[0031] Embodiment 1: Preparation of tackifying resin modified acrylate prepolymer:

[0032] Take hydroxyethyl methacrylate: 40kg, acrylic acid: 45kg, butyl acrylate: 180kg, isooctyl acrylate: 1240kg, methyl methacrylate: 20kg, vinyl acetate: 220kg, ethyl acetate: 2100kg, diperoxide Benzoyl (BPO): 6kg, Toluene: 130kg, Tackifying resin: 400kg. Among them, the tackifying resin can be rosin resin, hydrogenated rosin resin or rosin / C5 copolymer resin.

[0033] The preparation method is as follows

[0034] (1) Hydroxyethyl methacrylate, acrylic acid, butyl acrylate, acrylic acid

[0035] Add isooctyl ester, vinyl acetate, methyl methacrylate and ethyl acetate into the reaction furnace and stir at a stirring speed of about 40-50r / min. Dissolve BPO in toluene, stir evenly, and put it into the titration tank;

[0036] (2) Heat the mixture in the furnace to 82°C through the jacket, and start adding the BPO solution dropwise,

[0037] The dropwise addition is completed within 2 hour...

Embodiment 2

[0043] Take 100 parts of the tackifying resin-modified acrylate prepolymer prepared in Example 1, add 0.8 part of di-n-butyltin dilaurate and 0.2 part of triphenylmethane triisocyanate to prepare a pressure-sensitive adhesive. The surface material of the label is 80g glossy powder paper, and the bottom paper is 140g single-sided release paper. Glue amount (dry glue) is 24g / m 2 , made of glossy paper pressure-sensitive labels. This glossy paper label has excellent initial tack at low temperature (-5~10°C), and can be used for frozen products or outdoor use in winter.

Embodiment 3

[0045]Take 100 parts of the tackifying resin-modified acrylate prepolymer prepared in Example 1, add 1.5 parts of N-methyl-2-pyrrolidone and 0.5 parts of tetraisocyanate to prepare a pressure-sensitive adhesive. The surface material of the label is 76μ synthetic paper, and the bottom paper is 140g single-sided release paper. Glue amount (dry glue) is 28g / m 2 , made of synthetic paper pressure sensitive labels. This synthetic paper label has excellent temperature resistance and can be used for identification and description of parts near the automobile engine, and can resist the corrosion of mixed steam such as water, steam, oil, etc. in the cover.

Abstract

The invention discloses an acrylate solvent-based pressure sensitive adhersive. The acrylate solvent-based pressure sensitive adhersive comprises, by weight, 100 parts of a tackifying resin modified acrylate prepolymer, 0.5-3 parts of a catalyst and 0.1-2 parts of a cross linking agent. The invention further discloses adhesive products prepared from the acrylate solvent-based pressure sensitive adhersive. The acrylate solvent-based pressure sensitive adhersive is characterized by: adopting the tackifying resin modified acrylate prepolymer as a main component, adding proper catalyst and proper cross linking agent according to different use requirements before being coated to adjust performance of the adhersive so as to satisfy performance requirements of a plurality of products, optimize product structures, raise production efficiency and facilitate product development and product transformation.

Description

technical field [0001] The invention relates to an acrylate solvent-type pressure-sensitive adhesive, and also relates to a product prepared from the acrylate solvent-type pressure-sensitive adhesive. Background technique [0002] Acrylic solvent-based pressure-sensitive adhesives have excellent pressure sensitivity and adhesion, so they are widely used in various pressure-sensitive adhesive products. However, with the continuous segmentation of the market, the customers who use them are becoming more and more specialized. There will be special requirements for a certain performance, such as heat resistance, cold resistance, radiation resistance, solvent resistance, oil resistance, etc. Usually, pressure-sensitive adhesive manufacturers prepare various types of pressure-sensitive adhesives through pressure-sensitive adhesive formula design and polymerization process adjustment to meet the needs of various customers. The shortcomings of this approach lead to the production o...
