Hard wax oil and preparation method thereof

Abstract

The invention provides hard wax oil prepared from the following components in parts by weight: 40-80 parts of vegetable oil, 3-15 parts of biological wax, 5-15 parts of rosin glycerol resin, 0.2-1.0 part of drier, 0.1-0.5 part of anti-skinning agent, 0.1-0.3 part of mixed UV (Ultra-Violet) absorber and 0.1-0.3 part of defoaming agent. The preparation method of the hard wax oil, which is provided by the invention, comprises the steps of generating bodied oil with relatively smaller molecular weight under the action of nitrogen protection and adding an oil-based UV absorber with synergy and a hindered amine light stabilizer, and thus the UV absorption performance of the hard wax oil is improved. The prepared hard wax oil is suitable for outdoor woodenware products, has good weatherability, favorable water resistance and ideal durability effect under the condition that sunlight and UV rays exist, and the hard wax oil hardly sags and has tough firm formed in coating construction, belongs to natural coatings, accords with the environmental protection requirement and can be also used for decorating private indoor rooms.

Description

technical field

[0001] The invention relates to the field of coatings, in particular to a wood wax oil and a preparation method thereof. Background technique

[0002] Today, people pay attention to the current buildings, wooden structures and indoor and outdoor decoration, such as: wooden ceilings, wooden floors, wooden walls, wooden door and window frames, wooden terraces, gazebos, wooden flower pots, furniture, wooden children's toys, wooden Most of the wood products such as handicrafts are painted with traditional paint, but when traditional paint is used outdoors, it mainly forms a layer of paint film with strong physical and chemical properties on the surface of the wood to seal the surface of the wood, making the wood unable to breathe, and it is easy to crack after a long time. The paint film is easy to fall off; when exposed to sunlight and ultraviolet rays, it is easy to produce yellowing, and the weather resistance and durability are poor; Harm, can no longer meet...

[0041] The preparation method of wood wax oil provided by the invention may further comprise the steps:

[0042] a) Take 40-80 parts by weight of vegetable oil, and pass it into nitrogen protection, and polymerize, and polymerize into molecules with relatively small molecular weights, which can effectively penetrate into the interior of wood and improve the weather resistance of wood wax oil , then adding 3-15 parts by weight of biological wax and 5-15 parts by weight of rosin glycerin resin to vegetable oil for mixing, heating up to 200°C-250°C for reaction, preferably for 7h-10h, and cooling to 30°C-60°C after the reaction;

[0043] b) Add the following components in parts by weight to the obtained mixture in sequence: 0.2-1.0 parts by weight of drier, 0.1-0.3 parts of mixed ultraviolet absorber, 0.1-0.5 parts of anti-skinning agent, 0.1-0.3 parts of defoamer, after mixing and stirring The output is wood wax oil.

Embodiment 1

[0046]Take 44 parts of soybean oil and 30 parts of linseed oil and mix them under nitrogen protection. Mix 10 parts of carnauba wax and 4.3 parts of beeswax, heat until melted, then add to the above mixed oil, stir and mix evenly, react at 200°C for 8 hours, and cool to 60°C; add 0.8 parts of rare earth drier, UV absorber and hindered amine light stabilizer at a weight ratio of 1:1, a total of 0.3 parts, 0.5 parts of butanone oxime, and 0.2 parts of defoamer, mix and stir for 5 minutes, and The product is produced. Example 2:

Embodiment 2

[0047] Take 30 parts of tung oil, 20 parts of linseed oil, and 10 parts of castor oil, and mix them with nitrogen protection at the same time. Mix 5 parts of carnauba wax and 3 parts of candelilla wax, heat until melted, then add to the above mixed oil and stir to mix evenly , reacted at 240°C for 7 hours, cooled to 50°C; sequentially added 0.5 parts of cobalt naphthenate drier, UV absorber and hindered amine light stabilizer at a weight ratio of 0.9:1, 0.2 parts in total, 0.5 parts of butanone oxime, 0.2 parts of defoamer, mixed and stirred for 5 minutes, and discharged after uniformity to obtain the product.
