Problems solved by technology

At the beginning, the choice of pigments was only for some automotive grades, but in tests and applications, it was found that the requirements for automobiles are only more than ten years, and the service life of buildings cannot be achieved.

Embodiment approach 1

[0027] Embodiment 1: Transparent fluorocarbon paint without color.

[0028] In 100 kg of finished fluorocarbon coatings, polyvinylidene fluoride accounts for 30 kg, acrylic resin accounts for 10 kg, isophorone accounts for 25 kg, and xylene accounts for 35 kg.

Embodiment approach 2

[0029] Embodiment 2: white fluorocarbon paint.

[0030] In 100 kg of finished fluorocarbon coatings, 25 kg of polyvinylidene fluoride, 15 kg of acrylic resin, 20 kg of isophorone, 25 kg of xylene, and 15 kg of titanium dioxide are used as pigments.

[0031] Below for embodiment one and embodiment two, give the embodiment of its production method respectively:

Embodiment approach 3

[0032] Embodiment 3: the production method of Embodiment 1.

[0033] a. Premixing, put 10 kg of acrylic resin, 25 kg of xylene, and 18 kg of isophorone into a disperser, mix and disperse at a low speed until the acrylic resin dissolves, and add 30 kg of polyvinylidene fluoride to see After less than polyvinylidene fluoride powder, start to disperse the mixture at high speed for 10 minutes until it is uniform, and then use 3 kg of isophorone to adjust the mixture to a viscosity of 90KU;

[0034] B. Sand milling, the viscosity of the premixed material after step a is adjusted to 75KU with 2 kilograms of isophorone, then put into the sand mill for chemical industry and carry out sand milling;

[0035] c. Dilute and adjust viscosity, use 5 kg of xylene and 2 kg of isophorone to dilute the abrasive material after step b, and disperse at high speed for 5 minutes until uniform, then add 5 kg of xylene to adjust the viscosity to meet the requirements of the finished product .

Abstract

The invention relates to the chemical field and in particular relates to paint and a production method thereof. The fluorocarbon paint mainly comprises the following steps of: adding pigments to polyvinylidene fluoride and thermoplastic acrylic resin by adopting dimethylbenzene and isophoron as solvents according to the color requirements; and obtaining the fluorocarbon paint through the processes such as pre-mixing, grinding, diluting, viscosity-adjusting and the like. The fluorocarbon paint disclosed by the invention can be extensively applied to the base materials of high-level external wall decorative protective materials such as aluminum curtain wallboards, color plates and the like, so that the service life of the building can be prolonged to several tens of years even hundreds of years, and the original color of the building is kept.

Description

[0001] This application is a divisional application of the patent application with application number 200810020484.0. The filing date of the original application is March 10, 2008. The title of the invention is "fluorocarbon coating and its production method". technical field [0002] The invention relates to the field of chemical industry, in particular to a paint and a production method thereof. Background technique [0003] Buildings, especially high-level buildings or buildings in harsh environments, such as public facilities, airports, commercial or office buildings, supermarkets, industrial plants, hangars and grain depots, etc., have to be protected for decades or centuries. Damage and always maintain a beautiful color, foreign scientists and architects have been studying, until the 1960s, the United States ElfAto company developed "Kynar500" as a trademark of polyvinylidene fluoride (PVDF) fluorocarbon resin, which contains a large amount of The F-C bond has a bond e...
