Problems solved by technology

However, the addition of UV absorbers will greatly reduce the transmittance of ultraviolet rays, and cannot achieve the effect of high UV transmittance. Therefore, in order to obtain high ultraviolet (UV) film, it is necessary to solve the negative impact of ultraviolet rays on the film after it passes through the film.

Embodiment 1

[0032] Specific steps are as follows:

[0033] 1) Plasticizer mixing: Dissolve free radical scavenger, antioxidant and quencher in plasticizer; mix 20g 770, 10g 1010, 10g168, 5g bis(3,5-di-tert-butyl-4 -Hydroxybenzyl phosphate monoethyl ester) Nickel is dissolved in 2.4kg triethylene glycol diisocaprylate (plasticizer), the temperature of heating and dissolving is 70°C, after complete dissolution, add 3g silane coupling agent and stir evenly, keep warm 60min standby.

[0034] 2) Mix and extrude the PVB resin powder and the plasticizer prepared in step 1) according to the mass ratio of 71:29, process, melt and plasticize, pass through the mold, make PVB film, cool and shape, and obtain the finished product.

Embodiment 2

[0036] Specific steps are as follows:

[0037]1) Plasticizer mixing: Dissolve free radical scavenger, antioxidant and quencher in plasticizer; mix 20g 770, 10g 1010, 10g168, 5g 2,2'-thiobis(4-tert Butylphenoxy)nickel was dissolved in 2.4kg of triethylene glycol diisocaprylate (plasticizer), and the temperature for heating and dissolving was 70°C.

Abstract

The invention discloses a PVB (Polyvinyl Butyral) film as well as a preparation method and application thereof. The PVB film comprises the following components: PVB resin, a plasticizer, an antioxidant, a quenching agent and a free radical scavenger. The PVB film prepared by the invention has good adhesion to glass, high ultraviolet transmittance, high light transmittance and strong aging resistance under the condition of not absorbing ultraviolet rays.

Description

technical field [0001] The invention relates to the technical field of polyvinyl butyral (PVB) materials, in particular to a PVB film and its preparation method and application. Background technique [0002] In recent years, with the rapid development of construction and automobile industries, PVB film is also called PVB film or PVB interlayer. It is the best material for making laminated safety glass in the world today. PVB film is made of PVB resin. The resin is non-toxic, odorless, non-corrosive, not easy to burn, and has good light transmission, insulation, weather resistance, wear resistance, water resistance, oil resistance, and aging resistance. Plexiglass has special adhesion and light transmission properties. Therefore, PVB films with high strength and moisture resistance can be widely used in automobiles, buildings, various bulletproof glasses, aerospace vehicles, military instruments, solar cells, composite shock-absorbing steel plates for industry, etc., and ha...
