Problems solved by technology

[0005] As far as the domestic market is concerned, there are many optical disc manufacturers, but the adhesive is controlled by a few large companies, including Japan's DIC, SONY, and Taiwan's Changxing. Few domestic manufacturers can compete with them. The main reason is that these companies The products are relatively cost-effective

Embodiment 1

[0031] In a 5000ml reaction bottle, put 3000g of NPGDA first, then 1250g of DPGDA, start stirring, raise the temperature to 60°C, then add 600g of TMPTA, and then add 50g of photoinitiator 184. Keep the temperature at 60°C, stir for 2 hours, and then filter through a 0.1um filter to obtain the product. Yield 100%.

Embodiment 2

[0033] In a 5000ml reaction bottle, put 3000g of NPGDA first, then 1100g of DPGDA, start stirring, raise the temperature to 55°C, then add 550g of TMPTA, and then add 50g of photoinitiator 184. Keep the temperature at 55°C, stir for 2.5 hours, and then filter through a 0.1um filter to obtain the product. Yield 100%.

Embodiment 3

[0035] In a 5000ml reaction bottle, put 3000g of NPGDA first, then 1300g of DPGDA, start stirring, raise the temperature to 65°C, then add 700g of TMPTA, and then add 55g of photoinitiator 184. Keep the temperature at 65°C, stir for 1.5 hours, and then filter through a 0.1um filter to obtain the product. Yield 100%.

[0036] The UV curable adhesives of Examples 1 to 3 are coated on the surface of polycarbonate plastic sheets by spin coating, cured by ultraviolet light to form a coating film, and the performance of the coating film is tested. The results show that the results of Examples 1 to 3 All UV curable adhesives have a good appearance, the adhesion is grade 1 (tested according to GB / T9286-1998, the evaluation results are divided into 5 grades, 0 is the best, and 5 is the worst), and the hardness is above grade B (according to GB / T9286-1998 / T6739-1996 method detection), acid resistance (the test board is immersed in 5% sulfuric acid at 25 ° C, and the appearance is good...

Abstract

The invention relates to an UV (ultraviolet) curable adhesive and a preparation method thereof. The UV curable adhesive is prepared from the following raw materials: 10-15 parts of bisphenol A epoxy acrylate oligomer, 25-35 parts of phenoxy ethyl acrylate monomer, 4-8 parts of diethylene glycol diacrylate monomer and 0.3-0.8 part of photoinitiator 184. The preparation method of the UV curable adhesive comprises the following steps: firstly putting the phenoxy ethyl acrylate monomer, then putting the bisphenol A epoxy acrylate oligomer into a reactor, starting stirring, raising the temperature to 55-65 DEG C, adding the diethylene glycol diacrylate monomer, then adding the photoinitiator 184, maintaining the temperature at 55-65 DEG C, stirring the materials for 1.5-3 hours and then filtering the product with a 0.1mu m filter, thus obtaining the UV curable adhesive. The UV curable adhesive is applied to the surfaces of DVDs (digital versatile discs), has level-one adhesive force and hardness above level B, is resistant to acid and alkali, has excellent combination properties and is relatively low in cost.

Description

technical field [0001] The invention relates to a UV curable glue and a preparation method thereof. Background technique [0002] Ultraviolet curing technology (UV technology for short) is considered an environmentally friendly green technology, also known as 3E technology, namely energy saving, environmental protection and economy, and is mainly used in coatings, inks, adhesives and other fields. Among them, ultraviolet curing UV glue is widely used in glass products and jewelry industry, glass furniture, medical equipment, electronics, electrical appliances, optoelectronics, optical instruments, manufacturing and other fields, such as electronic circuit boards, electronic components, digital cameras, electronic scale manufacturing, honeycomb Manufacture of song film and other products. [0003] An important application field of UV-curable adhesive is adhesive or protective adhesive for optical discs. In the early stage of the development of optical discs, there were seve...
