Abstract

The invention belongs to the technical field of tensile testing of a thin film, and particularly relates to a tensile testing machine for the thin film and a tensile testing method. The tensile testing machine for the thin film comprises a base, X-axis bidirectional screw rods, X-axis movable slide bars, Y-axis bidirectional screw rods, Y-axis movable slide bars, planar movable sliders, shear forkexpansion brackets, thin film clamping devices and motor drive devices, wherein the two X-axis bidirectional screw rods and the Y-axis bidirectional screw rods are mounted on the base, and the shearfork expansion brackets are mounted between every two adjacent planar movable sliders; a plurality of thin film clamping devices are uniformly mounted on the shear fork expansion brackets; each thin film clamping device comprises a lower clamp seat, an upper clamp seat and a clamp cylinder. Testing raw materials can be substantially reduced, testing time is shortened, and testing cost is saved. Besides, the tensile temperature and the tensile speed of the tensile testing machine can be subjected to gradient selection, curing tensile test of a coating film can be performed, a uniaxial tension technology after online coating of the coating film is imitated completely, optimized research of a coating liquid formula is performed, and diversified demands are met.

Description

technical field [0001] The invention belongs to the technical field of film tensile testing, in particular to a film tensile testing machine and a tensile testing method. Background technique [0002] At present, there are more and more high-value-added varieties of plastic films in China, and the research and development of functional films cannot meet the surface treatment requirements of existing films, that is, corona treatment. Therefore, more research and development of polyester with online pre-coating treatment is required. Films are used to improve surface adhesion, antistatic and other requirements. The key point of online pre-coating polyester film is the coordination of pre-coating agent formula and production line. If it is not suitable, it will easily produce coating lines and cannot be used, or the effect of pre-coating cannot be achieved, and a functional surface cannot be obtained. Since changes in film thickness, production line speed, and coating liquid f...
