Abstract

The present invention discloses a glass fibre reinforcement and surface modification method in the material manufacturing field of the automotive upholstery. According to the method, firstly, a modified polyurethane waterborne emulsion is prepared. Secondly, a water-soluble polyester, the modified polyurethane waterborne emulsion, the gamma-propyl-trimethoxy-silane, the gamma-propyl tri-methoxy silane, the deionized water, an ammonium salt and a fatty acid amide are adopted as raw materials and are mixed up to prepare a dipping solution. After that, a continuous glass fiber mat is immersed in the dipping solution and is taken out of the dipping solution after being subjected to supersonic vibration and impregnation. The obtained continuous glass fiber mat is dried while being kept out of the sun, and then a reinforced and surface-modified continuous glass fiber mat. According to the invention, the gamma-propyl-trimethoxy-silane and the gamma-propyl tri-methoxy silane are adopted as coupling agents to react with polyurethane to generate a copolymer. In this way, the interface performance of the fiber mat with a resin matrix is improved. Products obtained through the above method can be used for manufacturing the automotive upholstery and automotive structural parts, which have the advantages of light weight, small thickness and low cost under the same intensity.

Description

technical field [0001] The invention relates to a composite material which can be used for manufacturing automobile interior parts and a manufacturing method thereof, in particular to a composite material of glass fiber and polyurethane. Background technique [0002] Glass fiber continuous mat is a new type of inorganic reinforcement material, which is widely used in electrical appliances, automobiles and other industries due to its excellent performance. Glass fiber continuous strand mat is isotropic, with high isotropic strength, high bond strength between layers, and high porosity. Because of its advantages of fast and uniform resin penetration, it is more and more used in the automotive industry. Wide, such as used in the manufacture of interior parts, structural parts, etc. Its disadvantage is that when this glass fiber continuous mat is used to manufacture automotive interior parts and structural parts, it has the disadvantage of large dust, which will cause great har...
