Problems solved by technology

[0003] Although wood protection has been regarded as an important technology that can save wood consumption and improve the service life of wood, the current research and application of wood protection are limited to simple termite control and flame retardant treatment, and there is no comprehensive treatment from wood drying, anticorrosion, insect protection, and moisture resistance. , anti-mildew, anti-termite, anti-crack, flame retardant, modification and other aspects are considered comprehensively to improve its overall grade
On the other hand, due to the strengthening of people's awareness of environmental protection and the various green barriers faced by exporting wood products, it has become the main choice of wood protective agents from the aspects of colorless, odorless, high efficiency, low toxicity, pollution-free, multi-functional and environmentally friendly. Therefore, the use of formaldehyde or formaldehyde-containing organic substances for protection has become a restricted and prohibited use of protective agent raw materials and supplies

Embodiment 1

[0026] Embodiment 1 gets each raw material by following weight parts:

[0027] 54 parts of linseed oil, 35 parts of tung oil, 10 parts of crude beeswax, 1 part of iron oxide, 0.01 part of catalyst,

[0028] Heat linseed oil and tung oil together at 250-290°C for 10-12 hours, react to the end and then when the temperature drops to 80-90°C, disperse and add the wax at high speed, then add inorganic pigments and rare earth drier, stir and mix evenly , to obtain the wood wax oil.

[0029] The wood wax oil for wood protection can be directly used for spray protection of wood products, and can also be used for infiltration of molded products after dilution with environmentally friendly organic solvents. After testing, the treated wood products will not produce any toxic and harmful substances. At the same time, it can meet the excellent performance of breathability, waterproof, moisture-proof, insect-proof, anti-corrosion and crack-proof.

Embodiment 2

[0030] Embodiment 2 gets each raw material by following weight parts:

[0031] 60 parts of sunflower oil, 25 parts of tung oil, 10 parts of carnauba wax, 5 parts of iron oxide, 0.1 part of catalyst, heat sunflower oil and tung oil at 250-290 ° C for 10-12 hours, react to the end and then the temperature drops to 80 At -90°C, disperse and add wax at high speed, then add inorganic pigment and rare earth drier, stir and mix evenly to obtain the wood wax oil.

Embodiment 3

[0032] Embodiment 3 gets each raw material by following weight parts:

[0033] 60 parts of soybean oil, 15 parts of carnauba wax, 1 part of iron oxide, 0.1 part of catalyst, 0.3 part of commercially available modified silicone oil dispersant, 0.01 part of dimethyl silicone oil defoamer,

[0034] Heat and melt carnauba wax, then filter to obtain refined carnauba wax, then add soybean oil and catalyst, stir and react for 40 minutes under temperature control conditions of 180-250°C, then add iron oxide, commercially available modified silicone oil dispersant and Simethicone defoamer, stirred until evenly mixed to obtain the wood wax oil in paste form.

Abstract

The invention discloses wood wax oil for protecting wood and a method for preparing the same. The raw materials of the wood wax oil comprise vegetable oil and wax, and the wood wax oil is characterized in that the compositions of the raw materials of the wood wax oil comprise vegetable oil, animal or vegetable wax, ferric oxide and a catalyst. The wood wax oil and the preparing process can protect the wood completely, can keep the elasticity and environmental protection performance of wood, can prevent the wood from cracking effectively and enable the wood to have various comprehensive properties such as drying, as well as corrosion, insects, moisture, mildew, termite, anti-cracking, and fire-retardant resistance, and the like, and meet all requirements of environmental protection, and does not to release any harmful substance during long-term use. The preparing process of the wood wax oil is simple and no organic solvent is needed to be added, thereby avoiding the incorporation of harmful substances.

Description

technical field [0001] The invention belongs to the technical field of chemicals for protection of wood and wood products, and in particular relates to a wood wax oil for wood protection that can comprehensively protect wood and fully meet environmental protection requirements and a preparation process thereof. Background technique [0002] Wood products are still one of the most commonly used products in people's daily household and utensils. Wood protection refers to reducing or avoiding the damage of various biological or abiotic factors to wood by physical, chemical and biological means, improving wood quality and improving wood quality. use value. Including wood anti-corrosion, anti-mildew, anti-insect, wood flame retardant and wood modification, it is the most important technical policy and measure for rational utilization and saving of wood, which has been proved by long-term practice at home and abroad. [0003] Although wood protection has been regarded as an impor...
