Abstract

The invention discloses a ultra-low temperature anti-penetration PVB interlayer film. The interlayer film comprises an interlayer film body, wherein the interlayer film body is made from high-viscosity PVB resin, a fiber reinforced layer is compounded in the interlayer film body, and a plurality of bulges are formed on the upper surface and lower surface of the fiber reinforced layer; and a compound plasticizer which is triethylene glycol diisooctanoate is compounded in the interlayer film body. Compared with a conventional product, the interlayer film has the characteristic of better anti-penetration performance, can be applied to manufacture of interlayer safety glass and meet high-level safety requirements for strong penetration resistance, and can be widely applied to the fields of front and rear windshields of an automobile, bulletproof glass and the like, so that technological progress of a domestic PVB interlayer film is facilitated, the international competitiveness of the domestic PVB interlayer film is improved, and a positive promoting effect on the competitiveness and brand building of enterprises is achieved.

Description

technical field [0001] The invention relates to an ultra-low temperature anti-penetration PVB intermediate film. Background technique [0002] Polyvinyl butyral (PVB) film is the most widely used material in architectural laminated glass and automobile laminated windshield glass. It has good light transmission, adhesion, toughness and optical properties. The PVB interlayer film can firmly bond the two outer layers of glass together, making the laminated glass have strong impact resistance and energy-absorbing buffering functions, providing protection for the personal safety of users. [0003] The total production capacity of PVB interlayer film in the world is insufficient, mainly because the production technology requirements of PVB interlayer film are relatively high, only a few countries can produce independently, and the major manufacturers with advanced PVB interlayer film production technology strictly keep their technology secret, which is even more serious The unbal...
