Embodiment Construction

[0006] The invention adopts thermosetting resin-unsaturated polyester as the main processing material, and the processing method of resin transfer molding. Its processing technology: place the dry fiber prefabricated reinforcement (Perform) in the mold cavity, and then inject the liquid resin containing the initiator through external pressure or vacuum or both methods, so that the fiber can be impregnated. The preform acts as the skeleton of the material, and the orientation of the fibers lays the foundation for the high strength and high modulus of the part. After the reaction is complete, the part is removed and the whole process is recycled. This method is suitable for mass production, thereby saving costs. Before the resin reaches the gel point, there is a long working period (several hours) so that the resin can completely fill the entire cavity of the complex shape. When the injection temperature is reached, the resin viscosity becomes low, fully impregnates the prefor...

Abstract

The invention discloses a processing technology of a novel composite material antitheft door for home life. The processing technology is especially suitable for processing the antitheft door for home life and includes following steps: (1) placing a dried fiber preformed reinforcing member (Perform); and (2) injecting a liquid resin containing an initiator through an external pressure method, a vacuum method or a method including both the two to impregnate the fiber. The invention is advantaged in that the resin transfer moulding method is a closed die technology which can produce a unit being good in integration, high in quality and high in performances with only low-pressure devices being required. In addition, the processing technology is easy to carry out in large scale and can reduce cost.

Description

technical field [0001] The invention discloses a processing technology of a novel composite material anti-theft door, which is particularly suitable for the processing of household anti-theft doors. Background technique [0002] At present, in the processing technology of the traditional household anti-theft door, it is directly made of cast iron material through cutting, bending and post-processing, which has low impact strength, low bending strength and low safety performance. The processing technology of the anti-theft door directly affects the safety performance of the anti-theft door, and then affects the safety of the whole family. Therefore, in order to solve the above problems, the present invention provides a processing technology for household anti-theft doors, which can increase the impact strength of household anti-theft doors, has good bending strength, good thermal stability, good safety, and is widely used. Contents of the invention [0003] The object of t...
