How to choose wood paint? Oil, water-based paint silly.

Written in front

Traditional paint is divided into plant-based paint, oil-based paint and water-based paint as well as the gradual use of many foreign countries in the past two years to get wood wax oil, the following briefly introduce their differences and performance.

A traditional plant paint

Simply put, the plant paint is actually from the ancient paint development over, the ancients used to use tung oil to do the paint, the main ingredient is the glycerol ester of tung oil, brush will be absorbed by the wood in the interior, cooked tung oil advantages: fast drying, light specific gravity, good gloss, strong adhesion, heat, acid and alkali resistance, corrosion, Anti-corrosion, anti-rust and other characteristics. Disadvantages: single texture, toxicity. Nowadays, it is mainly used to make oil-based paint, ink or medical and chemical purposes.

Two, oil-based paint

Earlier in the time or oil-based wood lacquer market share, the main types of polyurethane (PU) lacquer is the most widely used, followed by nitro (NC) lacquer and polyester (PE) lacquer and UV lacquer of these kinds.

NC paint

The main film-forming material is nitrocellulose, advantages: fast drying, easy to refurbish, surface drying even coated, feel good. Disadvantages: the film thickness is poor to repeatedly brush, and alkali solvent resistance is poor, temperature resistance, aging resistance are poor, easy to discoloration cracking, etc., the biggest problem is not environmentally friendly, oil-based paint pollutants mainly from diluents and curing agents, etc., their volatiles contain benzene and other hazardous substances, general use 1-2 months, basically can not smell anything, but the harmful gases will continue to evaporate for several 10 years.

PU paint

Polyurethane paint adhesion, durability and film gloss are relatively excellent, but the same indoor air has a lot of pollution, so foreign countries can not meet the environmental requirements and was eliminated.

PE paint

Because PU paint and NC paint environmental issues advantages and disadvantages are too obvious, so now gradually by the synthesis of better polyester (PE) paint replaced. Because the oil paint on the wood is closed protection, after painting attached to the wood surface, so it will cover the wood grain texture, feel will be smoother, if you want to buy oil paint or recommended to buy a better performance, VOC content to meet the national environmental standards of polyester paint.

? Third, water-based paint

Earlier water-based paint is not mature, the shortcomings are also more obvious, film hardness and fullness is poor, and oil-based paint film effect is not comparable, so not many people, but because of the development of these years of technological innovation is more rapid, the market share is also higher and higher, the most important characteristic of water-based paint is to use water as a diluent, so the relative VOC content is lower, the environmental grade is higher. The most important feature of water-based paint is that it uses water as a diluent, so it has a relatively low VOC content and a higher environmental rating.

Common water-based paint is mainly polyacrylic acid, acrylic acid and polyurethane composite?

These three types of waterborne paints are polyacrylic, acrylic and polyurethane composite, and pure polyurethane.

Pure polyurethane waterborne paint

The most superior overall performance, high fullness, high film hardness, wear-resistant performance even more than oil-based paint, service life, color mixing have obvious advantages. Good water-based paint performance is able to reach the oil-based paint, of course, the price will be higher, but in order to protect the environment is small.

? Fourth, wood wax oil

Wood wax oil should now be the most environmentally friendly, the best effect of wood paint, the main ingredients: raw materials are mainly to catalpa oil, linseed oil, thuja oil, pine oil, carnauba wax, plant resins and natural pigments fusion and become.

Wood wax oil and paint protection principle is different, wood wax oil is open, paint is closed. Paint is to protect wood products through the fully closed paint film, while the oil in wood wax oil can penetrate into the interior of the wood, and the wax can be tightly combined with the wood fiber to enhance the surface hardness, waterproof and anti-fouling, wear-resistant and resistant to abrasion.

Summary:

Environmental protection: wood wax oil＞water-based paint＞oil-based paint

Appearance and touch: wood wax oil＞oil-based paint≥water-based paint

Durability: oil-based paint≥water-based paint＞wood wax oil

Hardness and abrasion resistance: oil-based paint≥water-based paint＞wood wax oil

Weatherability: Wood wax oil > water-based paint ≥ oil-based paint

So the integrated environmental protection and performance of the two blocks of wood wax oil should be the most environmentally friendly wood paint, water-based paint is currently the most balanced performance of wood paint, oil-based paint is the closure and lacquer effect of the best wood paint.
