Embodiment 1

[0019] An ultraviolet curing adhesive is composed of a binder and a toughening agent, the binder is bisphenol A epoxy acrylate, and the toughening agent is flexible acrylic urethane.

[0020] The parts by weight of the raw materials are 20 parts by weight of bisphenol A type epoxy acrylate, and 35 parts by weight of flexible acrylic urethane.

Embodiment 2

[0022] An ultraviolet curing adhesive is composed of a binder and a toughening agent, the binder is bisphenol A epoxy acrylate, and the toughening agent is flexible acrylic urethane.

[0023] The parts by weight of the raw materials are 35 parts by weight of bisphenol A epoxy acrylate and 43 parts by weight of flexible acrylic urethane.

Embodiment 3

[0025] An ultraviolet curing adhesive is composed of a binder and a toughening agent, the binder is bisphenol A epoxy acrylate, and the toughening agent is flexible acrylic urethane.

[0026] The parts by weight of the raw materials are 50 parts by weight of bisphenol A type epoxy acrylate, and 50 parts by weight of flexible acrylic urethane.

[0027] 1. Project product laboratory sample performance test

[0028] A. Good compatibility with liquid crystal

[0029] Fill the liquid crystal in the liquid crystal cell and seal it with this product, but it will not be cured. After several hours at room temperature, the photoelectric properties of the liquid crystal will not change.

[0030] B. High temperature and high humidity resistance

[0031] Use this product to seal and cure the liquid crystal cell. After placing it at room temperature for 24 hours, place it at a temperature of 85°C and a humidity of 95% for 1000 hours.

Abstract

The invention relates to an adhesive, in particular relates to an ultraviolet light solidified adhesive. The adhesive is formed by combining a binder and a flexibilizer, wherein the binder is bisphenol A type epoxy acrylate, and the flexibilizer is flexible propenoic carbamate. The adhesive has the advantages of rapid solidifying speed, large bonding strength, high light transmittance, no any adhesive layer bonding and no pollution, and is convenient to use and operate.

Description

1. Technical field [0001] The invention relates to an adhesive, in particular to an ultraviolet light curing adhesive. 2. Background technology [0002] As the main production place of liquid crystal displays in the world, my country relies almost entirely on imports of special sealing adhesives for LCDs, which is a technical barrier to the development of UV-curable adhesives in China and seriously hinders the localization process of my country's LCD manufacturing industry. At the same time, due to foreign LCD special sealing glue restrictions on my country's imports, hidden worries have been laid for the development of my country's LCD industry. In order to meet domestic application requirements, it is imminent to develop UV-curable adhesive products with high performance and low cost that can be applied to the high-end field of the electronics industry. 3. Contents of the invention [0003] The object of the present invention is to avoid the above disadvantages and prov...
