Problems solved by technology

Based on these advantages, FRP is now the first choice for the cover and base of automobile air conditioners to replace the previous metal cover and metal base. Often installed on the top of the car, FRP is easy to break, and the density of FRP is relatively high. Taking a 45-seat bus as an example, the weight of the cover and base of the vehicle air conditioner is about 120-150Kg, plus With the compressor installed, the total weight of the entire air-conditioning system is basically above 300Kg, and some even reach about 400Kg. The load is as high as two to three hundred kilograms, which virtually increases the energy consumption of the car, which is not conducive to energy conservation and environmental protection.
In addition, FRP is used to manufacture the cover plate and base of the vehicle air conditioner. Since the cover plate and the base are irregularly shaped parts, it is necessary to manually add a layer of base material, a layer of reinforcing fiber, and a layer of base material. , a layer of reinforcing fiber, so that it is repeatedly coated, and finally the FRP part body of the desired shape is obtained, and then it needs to be exposed to the sun for 4 to 6 hours, or baked in an oven at 100°C for 2 to 4 hours, This kind of FRP material is inefficient in the manufacture of the cover and base of the car air conditioner. The cover and base of a car air conditioner basically takes more than 4 hours, the production efficiency is low, and most of the work is done by manpower ,high cost

Abstract

The invention relates to air conditioner accessories for vehicles, in particular to a DCPD (dicyclopentadiene) composite material for cover plates of air conditioners for vehicles. According to the scheme, the DCPD composite material is prepared by mixing a material A and a material B according to a mass ratio that the A to the B is equal to 0.5 to 1.5, wherein the material comprises the following components in parts by weight: 85 to 98 parts of DCPD, 1 to 8 parts of a catalyst, 0.1 to 4 parts of a stabilizer and 0.1 to 4 parts of an additive; and the material B comprises the following components in parts by weight: 85 to 98 parts of DCPD, 5 to 10 parts of an activating agent and 0.5 to 5 parts of a regulator. The DCPD composite material for the automobile air conditioner cover plates, provided by the invention, has excellent performance, such as heat resistance, acid and alkali resistance, friction resistance and the like, has high insulativity, and can be used for manufacturing the cover plates of the air conditioners for the vehicles, wherein the cover plates include cover plates for automobile air conditioners, cover plates for train air conditioners, cover plates for subway air conditioners and the like.

Description

technical field [0001] The invention relates to an air conditioner accessory for a vehicle, in particular to a DCPD composite material for a cover plate of an air conditioner for a vehicle. Background technique [0002] At present, the cover plates of vehicle air conditioners on the market are made of glass fiber reinforced plastics. The scientific name of FRP is glass fiber reinforced plastic, commonly known as FRP (Fiber Reinforced Plastics), that is, fiber reinforced composite plastic. Fiber-reinforced composites are composed of reinforcing fibers and a matrix. According to the fiber used, it is divided into glass fiber reinforced composite plastic (GFRP), carbon fiber reinforced composite plastic (CFRP), boron fiber reinforced composite plastic, etc. It is a composite material with glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as reinforcing material and synthetic resin as a matrix material. The diameter of the fiber (or whisker) is very small, ge...
