Embodiment Construction

[0027] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the present invention, rather than Full examples.

[0028] The preparation method of the embodiment of the present invention alkyd resin is as follows:

[0029] In the production process operation, first check that the carbon dioxide is fed for 15 minutes (flow rate 5L / min), and then the vegetable oil, isooctanoic acid, diethylene glycol, phthalic anhydride, pentaerythritol, trimethylolpropane, and xylene materials are correct. Add it into the reaction kettle, and at the same time ensure that the temperature of the reaction kettle is lower than 50°C and add hypophosphorous acid. After the above materials are accurately put into the reactor, check that the vent valve of the reactor remains open (because the pro...

Abstract

The invention provides novel low-temperature easy-to-polish odorless alkyd resin. The alkyd resin is prepared from the following raw materials in parts by weight: 6 to 10 parts of C8 fatty acid, 11 to18 parts of odorless vegetable fat, 4 to 10 parts of polyhydroxy ether, 8 to 12 parts of a chain extender, 25 to 35 parts of intramolecular anhydride, 10 to 15 parts of pentaerythritol, 0.01 to 0.05part of a color reducer and 22 to 33 parts of a solvent. C8 saturated fatty acid is adopted, the problem that traditional alkyd resin is prone to precipitation due to incomplete reaction is solved, peculiar smell is reduced, and meanwhile, polyhydroxy ether, a chain extender and pentaerythritol are matched, so that the stability of the alkyd resin is improved.

Description

technical field [0001] The invention relates to an alkyd resin, in particular to a novel low-temperature, easy-to-polish, clean-odor alkyd resin and a preparation method thereof, which belong to the field of furniture decoration wood coating. Background technique [0002] In the field of furniture decoration and wood coating, the construction performance of the paint depends on the performance of the selected resin. The choice of a resin determines the main performance of the wood coating. Improving the performance of the resin is to increase the market share of the corresponding coating. At present, in the wood coating market, in the low-temperature construction in winter, spraying primers in thin spray thick coatings, etc., the abrasiveness has the disadvantage of sticking to sandpaper and difficult to polish. According to market demand analysis, it is developed in combination with environmental protection type and applied in the technical field of wood coating manufacturi...
