Abstract

The invention discloses a preparation method of a hydrophobic weather-resistant and aging-resistant composite fluorocarbon resin coating for a tent. The preparation method comprises the following steps of uniformly mixing sericite powder, silicon carbide ceramic particles, titanium dioxide coated with coupling modified aluminum oxide powder and cerium oxide, and silicon dioxide nanometer fluid, soas to obtain a pigment filler; adding a thinner and an additive into fluorocarbon resin of film-forming resin, uniformly stirring by a high-speed stirring machine, adding the uniformly mixed pigmentfiller, sand grinding and stirring by a sand mold high-speed stirring machine, adding a crosslinking curing agent, continuing to sand grind and stir until fully and uniformly mixing, putting into a vacuum drying box, vacuuming and defoaming. The coating with excellent corrosion-resistant property and aging-resistant property is prepared by using the fluorocarbon resin of film-forming resin as a substrate, using the diphenylmethane diisocyanate as the crosslinking curing agent, and using the titanium dioxide coated with cerium oxide, the silicon dioxide nanometer fluid, sericite, coupling agent-modified aluminum oxide powder and silicon carbide ceramic particles as the fillers, and is used for coating the tent; the weather-resistant and aging-resistant properties of the tent are improved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the field of tent coatings, in particular to a method for preparing a hydrophobic weather-resistant and aging-resistant composite fluorocarbon resin coating for tents. Background technique [0002] When carrying out activities in the wild, tents are often needed. Tents can provide people with a place to rest. When encountering rainy or hot weather, they can also be used to resist heavy rain and heat. The weather resistance puts forward a high test, such as the performance of rain resistance, sunlight resistance, high temperature resistance and so on. Most of the existing tents adopt common coatings, which have general properties, poor weather resistance, insufficient sunlight resistance and high temperature resistance. Contents of the invention [0003] The purpose of the present invention is to address the existing problems and provide a method for preparing a hydrophobic weather-resistant and aging-resistant composite fluo...
