A kind of composite crosslinking agent and application thereof for poe encapsulation adhesive film
A composite cross-linking agent and encapsulation film technology, which is applied in the direction of film/sheet adhesives, adhesives, adhesive additives, etc., can solve the problem that the production process of POE encapsulation film cannot meet the stability and communication requirements of the cast film production process at the same time. Linking high efficiency and other issues to achieve the effect of improving long-term use performance, increasing the degree of cross-linking, and reducing residues

Embodiment 1
[0055] The cross-linking agent in Comparative Example 1 is replaced by a composite cross-linking agent, which is composed of tert-butyl peroxycarbonate-2-ethylhexyl, 2,5-dimethyl-2,5-bis A mixture of (tert-butyl peroxide) hexane and N-methyldiallylamine, the mass ratio of the three: tert-butyl peroxycarbonate-2-ethylhexyl:2,5-dimethyl Base-2,5-bis(tert-butylperoxy)hexane:N-methyldiallylamine=4:1:1. Other components and consumption are identical with comparative example 1. According to the method and conditions described in Comparative Example 1, a cast film and a laminated cured film were prepared.
[0056] The cast film and laminated cured film prepared in Comparative Example 1, Comparative Example 2, Comparative Example 3 and Example 1 were respectively analyzed and tested, and the results are shown in Table 1.

Embodiment 2
[0061] The cross-linking agent in Comparative Example 1 is replaced by a composite cross-linking agent, and the composite cross-linking agent is made of tert-butyl peroxycarbonate-2-ethylhexyl, 2,5-dimethyl-2,5-bis The mixture of (tert-butyl peroxide) hexane and N-methyldiallylamine is adjusted to the mass ratio of the three respectively: (1) 6:1:1; (2) 5:1: 1; (3) 3:1:1; (4) 2:1:1. Other components and consumption are identical with comparative example 1. According to the method and conditions described in Comparative Example 1, a cast film and a laminated cured film were prepared.
[0062] The cast film and laminated cured film prepared by the composite crosslinking agent with different mass ratios in Example 2 were analyzed and tested, and the results are shown in Table 2.
