Oleophobic and hydrophobic waterborne paint and manufacturing and spraying method thereof

Abstract

The invention discloses a waterborne paint and a manufacturing and spraying method thereof. The invention aims to provide a safe, environment-friendly, oleophobic and hydrophobic waterborne paint anda manufacturing and spraying method thereof. The oleophobic and hydrophobic waterborne paint comprises the following components by mass: 5-20 parts of nano-silica, 5-10 parts of modified organic silicon resin; 5-20 parts of modified organic polysilazane; 5-10 parts of polysiloxane; 1-5 parts of a titanate coupling agent; 5-20 parts of nano-alumina; 5-20 parts of nano-zirconia; 1-10 parts of a siloxane coupling agent; 0.1-1 part of a leveling agent; 0.1-1 part of a wetting agent; 0.5-5 parts of a film-forming assistant; 0.1-3 parts of a non-stick assistant; 0.5-5 parts of a dispersant; 0.1-2 parts of a defoaming agent; 1-10 parts of a curing agent; and 10-30 parts of a diluents. The invention is mainly used for paint production.

Description

technical field [0001] The invention relates to a metal and plastic surface treatment process, in particular to an oil-repellent and water-repellent water-based paint and its manufacturing and spraying methods. Background technique [0002] In daily life, people use inorganic composite coatings on surfaces that are easily polluted by oil, such as kitchens, stoves, and disinfection cabinets, and most of the workpieces do not use coatings. It is resistant to acid and alkali, and does not have oleophobic and hydrophobic properties. The existing inorganic composite coatings usually include PTFE fluorocarbon coatings and silicone antirust paint or silicone powder used on the surface of tableware. The use of PTFE fluorocarbon coatings mainly has the following disadvantages: it is not environmentally friendly, and it is easy to produce toxic gas after being heated, and the poisonous gas damage was not discovered until 30 years later. High requirements, waste of energy, complicated...

AI Technical Summary

Problems solved by technology

[0002] In daily life, people use inorganic composite coatings on surfaces that are easily polluted by oil, such as kitchens, stoves, and disinfection cabinets, and most of the workpieces do not use coatings. Acid and alkali resistance, not oleophobic and hydrophobic, and the existing inorganic composite coatings usually include PTFE fluorocarbon coatings and silicone antirust paint or silicone powder used on the surface of tableware, etc.

The use of PTFE fluorocarbon coatings mainly has the following disadvantages: it is not environmentally friendly, and it is easy to produce toxic gas after being heated, and the poisonous gas damage was not discovered until 30 years later. High requirements, waste of energy, complex processing, need 3 layers of spraying, hardness ≤ 2H, not wear-resistant, non-sticky, poor self-cleaning, not weather-resistant

Silicone antirust paint or silicone powder spraying mainly has the following disadvantages: not environmentally friendly, easy to oxidize and pollute the environment, not resistant to weather, acid, and salt; fast aging, expensive maintenance costs, fast discoloration and easy cracking and peeling, hardness ≤ 2H, easy to scratch
