Connection structure of automobile skylight and water draining pipe

Abstract

Disclosed is a connection structure of an automobile skylight and a water draining pipe. The connection structure comprises a tubular-structure skylight water draining outlet and a skylight water draining pipe. The skylight water draining outlet is connected with a conduit. One end of the conduit is connected with the skylight water draining outlet. The other end of the conduit is arranged on an automobile chassis. The inner wall of the skylight water draining outlet and the inner wall of the skylight water draining pipe are both coated with waterproof paint which comprises a hydrophobing agent, inorganic pigment, a dispersing agent, a film-forming agent, a thickening agent, auxiliaries and pure acrylic emulsion. The hydrophobing agent is a hydrophobing composite. The hydrophobing composite comprises, by weight, 5-10 parts of inorganic oxide particles, 10-15 parts of organosilane, 1-3 parts of methylcellulose and 20-30 parts of ethanol. The inorganic oxide particles are composed of micron-grade particles and nanometer-grade particles. The mass ratio of the micron-grade particles to the nanometer-grade particles is 8:1. The average particle size of the micron-grade particles is 1 [mu]m-20 [mu]m. The average particle size of the nanometer-grade particles is 50 nm-200 nm. Through arrangement of the waterproof paint, the problem of water erosion can be prevented effectively.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a connection structure between an auto sunroof and a drain pipe. Background technique [0002] The car sunroof is widely used in the field of automobile technology. The car sunroof can quickly remove the fog inside the car, quickly cool down and save energy, improve the environment inside the car, and bring healthy and comfortable enjoyment to people. At the same time, car windows can also broaden the field of vision, and are often used for shooting needs of mobile photography. [0003] There are many problems in the design of the existing sunroof on the sunroof drain pipe, such as blockage and deformation caused by rain erosion for a long time, so there is an urgent need for a new type of connection between the car sunroof and the drain pipe structure. Contents of the invention [0004] The object of the present invention is to provide a connection structure b...
