Problems solved by technology

There are the following disadvantages: (1) Since the density of glass fiber cloth and glass fiber mat is more than twice that of epoxy resin, the proportion of composite resin is greatly increased, and with the increase of the above-mentioned filler ratio, the density of composite resin Increased brittleness and decreased impact resistance
(2) Although brominated epoxy resin has good flame resistance, it has become a pollutant that diffuses everywhere in the daily environment, and it will release harmful substances during combustion and heating, polluting the environment and endangering human health

Abstract

The invention relates to the technical field of automobile manufacturing, and concretely to an automobile interior decorative part and a preparation method thereof. The automobile interior decorativepart includes a fabric and composite resin connected to the fabric in an injection moulding manner. The composite resin is prepared by the following raw materials based on 100 parts of epoxy resin, byweight: 100 parts of epoxy resin, 5-20 parts of a chlorine source, 10-40 parts of polyether polyol, 12-48 parts of isocyanate, 5-12 parts of a catalyst, 3-15 parts of reinhanced fibers, 1-10 parts ofa chain extender, 2-8 parts of a surfactant, 10-15 parts of a curing agent, and 80-200 parts of an organic solvent. According to the method, the epoxy resin is modified by using the chlorine source so as to improve the flame retardant and smoke suppression properties of the epoxy resin. The epoxy resin continuously reacts with the polyether polyol and the isocyanate to produce the composite resinof the epoxy resin and polyurethane. Through the synergistic effect of the epoxy resin and the polyurethane, the composite resin can have high toughness, high strength and excellent flame retardancy.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile interior trim and a preparation method thereof. Background technique [0002] With the rapid development of the world economy and the continuous improvement of people's lives, the automobile industry is developing rapidly, the production of cars is changing with each passing day, and the car models are constantly being updated. People's requirements for cars are not only the beautiful appearance, but also the comfort, integrity and functionality of the interior decoration. It is required that these materials not only have the characteristics of heat insulation, noise reduction, shock resistance, flame retardancy, aesthetics and practicality, but also require structural door panel materials and other structural interior materials of some functional parts such as CD boxes and instrument boxes to have the following requirements (1) It has certain impa...
