Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] According to the enlightenment of silkworm cocoon materials and structures in the biological world, the present invention selects 10 layers of glass with different strengths (decreasing from inside to outside), and the distribution direction of each layer of glass fiber is anisotropic, and a suitable PVB material is selected between each layer of glass As the intermediate film, it is preheated and pre-pressed at 120°C-140°C, and at the same time, each side is vacuumed with a vacuum tube to bond the layers of glass together to prevent damage caused by glass fragments after impact.

[0033] Such as figure 1 As shown, the main structure of the multi-layer impact-resistant laminated glass based on the cocoon gradient layered structure, its main components are 10 layers of plexiglass with decreasing strength from inside to outside and PVB interlayer...

Abstract

The invention discloses multi-layer anti-shock sandwich glass based on silkworm cocoon fiber distribution and a gradient laminated structure and a preparation method. According to the multi-layer anti-shock sandwich glass disclosed by the invention, multiple layers of glass in different strength (the strength is decreased progressively from inside to outside) are selected, the fiber distribution directions of all layers of glass are anisotropic, materials such as PVB (Poly Vinyl Butyral) selected between every two layers of glass are used as intermediate membranes, all layers of glass are adhered together through high temperature and high pressure or vacuum pumping, and the damage caused by glass fragments after a shock can be prevented. The multi-layer anti-shock sandwich glass achieves a better buffer energy absorption effect, so that the anti-shock performance of existing sandwich glass is further increased, and the potential safety hazard is reduced.

Description

technical field [0001] The invention relates to the field of industrial materials and auto parts, in particular to a multi-layer impact-resistant laminated glass based on cocoon fiber distribution and gradient layered structure and a preparation method thereof. Background technique [0002] With the gradual development of science and technology, laminated glass is widely used in aviation, automobile, construction, industry and other fields due to its excellent performance. Compared with traditional glass, laminated glass has the following advantages: (1) It is safer and can remain intact even if it is broken. The safety of relevant personnel; (2) good impact resistance, able to withstand the impact of hammers, bricks, etc., can be used in museums, jewelry stores and other places that need to protect valuables; (3) good sound insulation effect, can be used in factories, Workshops and other places that require high sound insulation effect. [0003] The existing laminated gla...
