Polytetrafluoroethylene modified vinyl floor coating

Abstract

The invention discloses formula components, a preparation process and other contents of a polytetrafluoroethylene modified vinyl floor coating, which is called FVC floor coating for short, the coating comprises three components of A, B and C, wherein the A component is prepared by 9 substances of vinyl resin, polytetrafluoroethylene resin, polyvinyl chloride resin, anionic carboxylic polymer dispersant and the like, the B component is methyl ethyl ketone peroxide, and the C component is cobalt naphthenate. When in use, the A component, the B component and the C component are mixed for preparing the polytetrafluoroethylene modified vinyl floor coating according to the weight ratio of 100: 1.5-4: 1.5-4. The invention simultaneously discloses a formula and the preparation process of producing an anti-corrosion floor by using the polytetrafluoroethylene modified vinyl floor coating, and the polytetrafluoroethylene modified vinyl floor coating is characterized by excellent chemical medium corrosion resistance, weather resistance, oil resistance, water resistance, good mechanical properties, construction performance and the like, as well as long service life, and good anti-cracking performance, and can be used in chemical industry, petroleum, foods, pharmaceutical industry and the like as protective materials of surface layers of basal bodies, such as concrete floors, wall surfaces and other building structures, members and the like.

Description

1. Technical field [0001] The invention is a multi-component solvent-based polytetrafluoroethylene modified vinyl floor paint, referred to as FVC floor paint, which belongs to the technical field of industrial anticorrosion. 2. Technical background [0002] The anti-corrosion floor coatings commonly used in the market currently include epoxy floor coatings, chlorosulfonated polyethylene floor coatings, unsaturated polyester resin floor coatings, etc. They have their own advantages, some have better water resistance, and some are easy to construct. , and some have high adhesion, but there are generally disadvantages such as unsatisfactory coating corrosion resistance, short service life, and frequent renovation. Based on the existence of these problems, Zhejiang Yonggu Bi Coatings Co., Ltd. Together we researched and developed a new series of anti-corrosion coatings with excellent corrosion resistance, wide application, easy construction, good anti-cracking performance and lo...

Problems solved by technology

[0003] In order to solve the common problems of poor corrosion resistance, low floor strength and short service life in floor coatings, we have developed FVC series coatings, among which FVC floor coatings are polytetrafluoroethylene modified vinyl floor coatings. It is more outstanding. The formula of the floor coating introduces components such as polytetrafluoroethylene and polyvinyl chloride resin with excellent corrosion resistance and stable molecular structure, and develops a kind of anti-impact corrosion resistant to most acids, alkalis and salts. It is a polytetrafluoroethylene modified vinyl floor coating with outstanding performance, easy construction, good anti-cracking performance and long service life. Form; B component is methyl ethyl ketone peroxide; C component is cobalt naphthenate, and the weight ratio formula of three components is: A component: B component: C component=100: 1.5-4: 1.5-4, The weight percent formula of component A is as follows: vinyl resin 70-75, polyvinyl chloride resin 3-7, polytetrafluoroethylene resin 1-5, anionic carboxylic acid polymer dispersant 0.3-0.7, iron oxide red 5-10 , barite powder 5-10, white carbon black 1-3, glass fiber 1-3, dioctyl phthalate 0.5-2, the preparation method of component A is: first put the vinyl resin into the reaction according to the proportion In the kettle and mixed at a speed of 300 rpm, at the same time, the specified amount of anionic carboxylic acid polymer dispersant, dioctyl phthalate, glass fiber, and white carbon black were put into the reactor and mixed at a low speed for 15 minutes. Then increase the stirring speed to a high-speed stirring of 600 revolutions per minute, and slowly add polytetrafluoroethylene resin and polyvinyl chloride resin, stir at high speed for 10 minutes, then add iron oxide red, barite powder and other components, and disperse evenly at high speed Stir at a low speed for another 30 minutes. Before construction, add a specified amount of methyl ethyl ketone peroxide to the above-mentioned component A. After stirring for 5 minutes, add a specified amount of cobalt naphthenate. After stirring for 5 minutes, It is dubbed into polytetrafluoroethylene modified vinyl floor coating
