Embodiment 1

[0029] A kind of good PVB film of weather resistance of the present embodiment comprises the raw material of following weight portion:

[0030] 55 parts of modified grafted PVB resin, 15 parts of graphene emulsion, 10 parts of zeolite-based composite weathering agent, 2 parts of active dispersant, 1 part of dibutyl sebacate toughening agent;

[0031] The preparation method of described modified grafted PVB resin is:

[0032] S1, PVB resin surface treatment: Put the PVB resin into a sodium carbonate solution with a mass fraction of 2% and soak for 10 minutes at a temperature of 45°C, then take it out, dry it, and then irradiate it with cobalt 60-γ rays. Irradiate for 20 minutes, the irradiation power is 150W, and the irradiation is over;

[0033] S2, steam explosion treatment: send PVB resin into the blasting pretreatment liquid, then carry out microwave treatment for 10 minutes, the processing power is 20W, after the treatment is completed, then send it into the steam explosi...

Abstract

The invention provides a PVB diaphragm with good weather resistance, comprising the following raw materials in parts by weight: 55-65 parts of modified grafted PVB resin, 15-25 parts of graphene emulsion, 10-20 parts of zeolite-based composite weather resistance agent, Active dispersant 2-8 parts, dibutyl sebacate toughening agent 1-5 parts. The bentonite of the present invention is treated in a rare earth medium to enhance its activity. After being treated with a coupling agent, the organophilic and inorganic properties of bentonite are perfected. The introduction of branches into PVB resin can significantly enhance the bonding force between PVB resin and inorganic raw materials and organic raw materials, thereby improving the weather resistance of the product as a whole.

Description

technical field [0001] The invention relates to the technical field of PVB membranes, in particular to a PVB membrane with good weather resistance and a preparation method thereof. Background technique [0002] PVB film is also called PVB film, PVB film, PVB interlayer, etc., and its chemical name is: polyvinyl butyral film. Its essence is a thermoplastic resin film, which is produced by PVB resin plus plasticizer. Since it is made of plastic resin, it has the characteristics of recyclable processing and repeated use. PVB film can be widely used in architectural laminated glass, automotive laminated glass, solar photovoltaic glass, bulletproof glass, soundproof glass, etc. It has good safety and prevents the glass from being broken due to external force and the fragments splashing and hurting people. In addition, it has sound insulation, UV protection, can be made into color or high transparency, and has optical application value, such as the application of solar photovolt...
