Problems solved by technology

However, some halogen flame retardants have harmful substances to the environment and human health, especially during the combustion process.
The addition of phosphorus-based flame retardants to polycarbonate seriously reduces the physical properties of the material, and the flame retardant performance cannot reach the UL94-VO level.

Abstract

The invention discloses a damage-proof automobile front hood supporting frame which comprises a trapezoidal body, supporting frame handles, limiting blocks and a positioning block. Supporting legs are mounted on the lower surface of the first edge of the trapezoidal body, elastic materials are connected to the lower portions of the supporting legs, and the elastic materials are prepared from an epoxy composition and a carbonic ester composition. The epoxy composition is composed of bis(2,3-epoxy cyclopentyl)ester, adipic acid bis(3,4-epoxy-6-methyl cyclohexyl formic acid), bis(4-amino-3-methyl cyclohexyl)methane, glass beads and methacrylic acid. The carbonic ester composition is composed of dinaphthyl, dicyclohexyl carbonic ester, mica, dyhydroxyl polydiethylsiloxane, amine phosphate and N-hydroxymethyl acrylamide. The damage-proof automobile front hood supporting frame is arranged on an automobile front cabin body and stabilized through the supporting legs and supporting feet, the supporting legs are located above automobile headlamps, the position of the supporting frame can be moved through the supporting frame handles, and the limiting blocks and the positioning block are matched to guarantee that a front hood is mounted in place.

Description

technical field [0001] The invention belongs to the field of automobile front cover assembly equipment, and in particular relates to a damage-resistant automobile front hatch cover support frame during front cover assembly, which can be used for precise control of the assembly process of the automobile front cover. Background technique [0002] Machinery manufacturing is a country's basic industry and a pillar industry for national economic development. It directly reflects a country's productivity level and is an important factor that distinguishes developing countries from developed countries. The automobile industry is a very important part of the machinery manufacturing industry. It can reflect a country's machinery manufacturing capabilities and represent a country's industrial level. Cars are generally composed of four basic parts: engine, chassis, body and electrical equipment. The engine casing surface belongs to the automobile automobile cover. There are many devi...
