Acrylic ester composition, preparation method of acrylic ester composition, and adhesive tape applying composition

Abstract

The invention discloses an acrylic ester composition, a preparation method of the acrylic ester composition, and an adhesive tape applying the composition. The acrylic ester composition is prepared by a reactive material, a tackifier and a diluting solvent, and the weight-average molecular weight of a prepared polymer is 200,000-1,000,000. The reactive material comprises the following components in parts by weight: 95-99 parts of acrylic ester, 2-5 parts of (methyl) acrylic acid, 0.1-0.3 parts of (methyl) hydroxyethyl acrylate, and 0.3-0.8 parts of initiating agent. The adhesive tape comprises a base material, and an acrylic ester adhesion agent coated on the base material, wherein the acrylic ester adhesion agent is mixed by the acrylic ester composition with a curing agent; the coating gram weight of the acrylic ester composition is 90-180g / m<2>; the acrylic ester composition accounts for 83-84% of the total weight of the adhesive tape; the curing agent accounts for 1-2% of the total weight of the adhesive tape; and the base material accounts for 5-16% of the total weight of the adhesive tape. Both the initial viscosity and the long-term viscosity of the adhesive tape prepared by the acrylic ester composition are excellent.

Description

technical field [0001] The invention relates to an acrylate composition, a preparation method thereof and an adhesive tape using the composition. Background technique [0002] Adhesive is a kind of fine chemical products widely used in various industries. It is characterized by rapid development, wide application and high economic benefits. It plays a huge role in industrial, civil, medical and military fields. It is a broad promising industry. Acrylic adhesives developed in the 1960s are copolymerized from acrylic (ester) monomers and other vinyl monomers. They can be divided into solvent-based, emulsion-based, hot-melt, and UV-curable types. They have the following properties: Advantages: 1. The formula is simple, generally do not need to use softeners, anti-aging agents, etc.; 2. The bonding range is wide, and it has good bonding performance to various materials such as ceramics, cement, wood and other polar or porous surfaces. Bonding polyester, polystyrene, polyolefin...

AI Technical Summary

Problems solved by technology

[0004] At present, the known adhesives generally adopt targeted formula design in order to meet the needs of different customers. At the same time, the current downstream customers of adhesive products lack in-depth knowledge of adhesives, and the incoming inspection cannot use professional equipment simultaneously to determine the quality of the product. Inferior, the method of hand feeling is generally used to judge the stickiness of adhesive products

Adhesive formulations on the market are designed according to customer usage and judgment methods for various reasons. They often focus on the initial adhesive performance of the product to ensure that customers have a good first impression of the product and adopt the product development method of this product. The product development method usually cannot maintain a long-term customer use cycle, and the product design plan that focuses on the initial stickiness will ignore the cohesive strength of the product's adhesive, and the product is easy to fall off during use, which cannot guarantee long-term good bonding
