Embodiment 1

[0023] This water-based wood oil is prepared by the following steps:

[0024] Step 1: Put 7 parts of linseed oil and 2 parts of trimethylolpropane (TMP) into the reaction kettle, stir and heat to about 120°C, then add 0.001 part of catalyst LIOH, continue to heat up to 230-240°C and keep warm for alcoholysis, When the ratio of alcoholysis with methanol is greater than 3, the temperature is lowered to 70° C. to obtain mixture 1.

[0025] Step 2: Add 14 parts of N-methylpyrrolidone (NMP), 4 parts of dimethylolpropionic acid (DMPA) and 8 parts of oligomer polyether diol to the mixture one in step one, evenly After mixing, adopt the isocyanate dropwise process to raise the temperature slowly and maintain the temperature at 60-70°C to obtain the mixture 2.

[0026] Step 3: Add 10 parts of toluene diisocyanate (TDI) dropwise to the mixture 2 in step 2 in one hour, then keep it warm for one hour and then raise the temperature to 80°C and keep it until NCO≤0.3%, then cool down to 60°...

Embodiment 2

[0028] This water-based wood oil is prepared by the following steps:

[0029] Step 1: Put 4 parts of linseed oil, 4 parts of soybean oil and 2 parts of trimethylolpropane (TMP) into the reactor, stir and heat to about 120°C, then add 0.001 part of catalyst LIOH, and continue to heat up to 230-240°C ℃ for alcoholysis, until the ratio of alcoholysis with methanol is greater than 3, the temperature is lowered to 70 ℃ to obtain the mixture 1.

[0030] Step 2: Add 14 parts of N-methylpyrrolidone (NMP), 4 parts of dimethylolpropionic acid (DMPA) and 8 parts of oligomer polyether diol to the mixture one in step one, evenly After mixing, adopt the isocyanate dropwise process to raise the temperature slowly and maintain the temperature at 60-70°C to obtain the mixture 2.

[0031] Step 3: Add 5 parts of toluene diisocyanate (TDI) and 7 parts of diphenylmethane diisocyanate (MDI) dropwise to the mixture 2 in step 2 in one hour, then heat it up to 80°C for one hour and keep it warm until...

Embodiment 3

[0033] This water-based wood oil is prepared by the following steps:

[0034] Step 1: Put 2 parts of tung oil, 6 parts and 0.5 parts of pentaerythritol (PE), 1.5 parts of trimethylolpropane (TMP) into the reaction kettle, stir and heat to about 120°C, then add 0.001 parts of LIOH catalyst, and continue to heat up Heat alcoholysis at 230-240°C until the ratio of alcoholysis with methanol is greater than 3, then lower the temperature to 70°C to obtain mixture 1.

[0035] Step 2: Add 14 parts of propylene glycol methyl ether (PM), 4 parts of dimethylol butyric acid (DMBA) and 8 parts of oligomer polyether diol to the mixture 1 in step 1, after uniform mixing , adopt the isocyanate dropwise process, slowly raise the temperature, and maintain the temperature at 60-70°C to obtain the mixture 2.

[0036] Step 3: Add 5 parts of diphenylmethane diisocyanate (MDI) and 9 parts of isophorone diisocyanate (IPDI) dropwise to the mixture in step 2 in one hour, then heat up to 80 Keep warm ...

Abstract

The invention discloses development and application of a waterborne wood oil. The waterborne wood oil is prepared from, by weight, 5-15% of natural vegetable oil, 1-5% of polyalcohol, 10-20% of a cosolvent, 3-8% of waterborne monomers, 8-15% of isocyanate, 7-15% of oligomer diol, 1-4% of a neutralizer, 50-65% of deionized water, 0.1-0.5% of a defoaming agent and 0.1-0.5% of a leveling agent. According to the development and application of the waterborne wood oil, the preparation process is simple, only a part of the environment-friendly cosolvent is used, desorption is not needed, the preparedproduct is light in smell, the VOC content is smaller than or equal to 200 g / L, and the requirement for environmental protection is met; the advantages of alkyd resin and polyurethane resin are integrated, and through reasonable matching of soft and hard segments in the product structure, the waterborne wood oil finally has good hardness and flexibility; no waterborne dryer needs to be added, theproduct is translucent with blue light, the deionized water can be added for adjustment according to the viscosity during construction, and the waterborne wood oil has the advantages of quick drying,high hardness, good water resistance and high adhesion and can be widely used in furniture coating and home decoration.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to the development and application of a water-based wood oil. Background technique [0002] Water-based wood oil is refined by the world's advanced technology and can be diluted with water. It is non-toxic, purely environmentally friendly, does not contain formaldehyde, benzene, toluene, xylene, lead, zinc and other toxic and harmful substances, and has no harm to humans, animals and plants. It is widely used And outdoor landscape anti-corrosion wood, gazebo wooden tables and chairs, etc. [0003] But the preparation technology of water-based wood oil on the market is comparatively complicated now, and has certain irritating smell, and in construction process, adhesion is not ideal, and drying process is comparatively slow, does not have higher hardness and water resistance simultaneously. Contents of the invention [0004] The purpose of the present invention is to provide a kind...
