Embodiment 1

[0017] The high-performance UV-curable anti-sticking agent for heat-sensitive substrates is prepared from the following raw materials in parts by weight: acrylate-modified polysiloxane prepolymer: 55 parts; pigment: 1 part; Benzoin methyl ether: 5 parts; lauryl methacrylate: 15 parts; 2,6-di-tert-butyl-p-cresol: 3 parts.

[0018] The acrylate-modified polysiloxane prepolymer is prepared by the following steps: mixing two-terminated hydroxyl dimethylpolysiloxane and γ-methacryloxypropyltrimethoxysilane and stirring, Then add dibutyltin dilaurate, heat to 80°C for 8 hours, and obtain it after purification.

[0019] Mix the acrylate-modified polysiloxane prepolymer, pigment, lauryl methacrylate, and 2,6-di-tert-butyl-p-cresol thoroughly, heat to 30°C and stir for 10 minutes, then add benzoin methyl ether, and stir uniform, and then let it stand to cool to obtain a high-performance UV-curable anti-adhesive agent for heat-sensitive substrates.

Embodiment 2

[0021] The high-performance UV-curable anti-sticking agent for heat-sensitive substrates is prepared from the following raw materials in parts by weight: acrylate-modified polysiloxane prepolymer: 60 parts; pigment: 2 parts; Benzoin ether: 4 parts; lauryl acrylate: 18 parts; 2,6-di-tert-butyl-p-cresol: 5 parts.

[0022] The acrylate-modified polysiloxane prepolymer is prepared by the following steps: mixing two-terminated hydroxyl dimethylpolysiloxane and γ-methacryloxypropyltrimethoxysilane and stirring, Then add dibutyltin dilaurate, heat to 100°C, continue for 10h, and obtain it after purification.

[0023] Mix acrylate-modified polysiloxane prepolymer, pigment, lauryl acrylate, and 2,6-di-tert-butyl-p-cresol thoroughly, heat to 50°C and stir for 30 minutes, then add benzoin ether, stir evenly, and then Standing and cooling to obtain a high-performance UV-curable anti-adhesive agent for heat-sensitive substrates.

Abstract

The invention relates to the technical field of adhesives and particularly relates to an ultraviolet curable adhesive for a thermosensitive substrate with high performance. The ultraviolet curable adhesive for a thermosensitive substrate with high performance is prepared from the following raw materials in parts by weight: 50-60 parts of acrylate modified polysiloxane prepolymers, 1-2 parts of pigment, 2-5 parts of photopolymerization initiator, 10-20 parts of reactive diluent and 1-5 parts of adjuvant. The ultraviolet curable adhesive is capable of saving energy sources, simplifying the process and improving the quality of a product, beneficial to environment protection and wide in development prospect.

Description

technical field [0001] The invention relates to the technical field of anti-adhesive agents, in particular to an ultraviolet curing anti-adhesive agent for high-performance heat-sensitive substrates. Background technique [0002] In pressure-sensitive substrates, just as important as pressure-sensitive adhesives are release agents. Among anti-adhesive products, polyorganosiloxane is the most widely used and relatively mature technology. Its development has roughly gone through three stages: solvent-based, emulsion-based and solvent-free (both heat-cured and radiation-cured). The first type consumes a lot of energy and resources, and is extremely dangerous in the production process. Currently, developed countries basically no longer use it; The quality is not stable. The heat-cured solvent-based anti-adhesive agent avoids the defects of the former good general type and has excellent product performance, but it is not suitable for the production requirements of heat-sensiti...
