Abstract

The invention discloses PVB (polyvinyl butyral) paste containing tungsten bronze and its preparing method. The PVB paste comprises, by weight, 35 to 45 parts of tungsten bronze, 3 to 7 parts of thermoplastic resin, 50 to 60 parts of plasticizer, 1 to 2 parts of surfactant, 2 to 3 parts of dispersant and 0.8 to 1 part of coupling agent. A membrane made of the PVB paste has long-lasting high thermal insulation, long service life and free of separation during usage and has good effect of blocking radiant heat and conductive heat; the defect that the ability to block the near-infrared area below 1400 nanometers is poor is overcome, and the effect of blocking the infrared of the band from 780 micrometers to 2500 micrometers is good; the texture of the PVB membrane and its color saturation are evidently improved; mistiness is decreased; transparency is good; the preparing method is simple and is easy to operate.

Description

technical field [0001] The invention relates to a PVB slurry containing tungsten bronze and a preparation method thereof, belonging to the field of polymers. Background technique [0002] The chemical name of PVB is polyvinyl butyral, which has high transparency, cold resistance and impact resistance. Good adhesion to metal, glass, wood, ceramics, fiber products, etc. The film made of PVB resin powder is used to make the interlayer material of safety glass. The safety glass has good transparency and high impact strength, and is widely used in high-rise buildings, aviation and automobile fields. [0003] PVB film itself has good light transmission and strong impact resistance, and has been widely used in high-rise building doors and windows in recent years. However, PVB itself has strong light transmission, and the heat insulation effect is not ideal, which may easily cause high indoor temperature. In order to improve the heat insulation effect of glass doors and windows, ...
