Embodiment 1

[0043] A wooden furniture surface waterproof coating, made of the following raw materials in parts by weight: 50 parts of modified propylene styrene emulsion, 4 parts of inorganic filler, 0.8 part of flame retardant, 1 part of defoamer, 0.5 part of leveling agent, wetting agent 1 part, 10 parts of deionized water;

[0044] The waterproof coating is made by the following steps:

[0045] The first step is to add deionized water into the container, add wetting agent, half of the defoamer, flame retardant and inorganic filler in sequence under 150r / min uniform stirring state, transfer to the ball mill and mill at 120r / min for 60min;

[0046] The second step, the mixture after ball milling is transferred to the container again, adjust the speed to 700r / min, add the modified propylene styrene emulsion, stir for 10min, add the remaining defoamer and leveling agent, continue stirring for 30-40min, then use 400 Mesh filter.

Embodiment 2

[0048] A wooden furniture surface waterproof coating, made of the following raw materials in parts by weight: 55 parts of modified propylbenzene emulsion, 5 parts of inorganic filler, 0.9 part of flame retardant, 1.5 parts of defoamer, 0.55 part of leveling agent, wetting agent 1.3 parts, 12 parts of deionized water;

[0049] The waterproof coating is made by the following steps:

[0050] The first step is to add deionized water into the container, add wetting agent, half of the defoamer, flame retardant and inorganic filler in turn under the state of 1700r / min uniform stirring, transfer to the ball mill and mill at 120r / min for 60min;

[0051] Step 2: Transfer the ball-milled mixture to the container again, adjust the speed to 750r / min, add the modified propylene styrene emulsion, stir for 15 minutes, add the remaining defoamer and leveling agent, continue stirring for 35 minutes, and use a 400-mesh sieve net filter.

Embodiment 3

[0053] A wooden furniture surface waterproof coating, made of the following raw materials in parts by weight: 60 parts of modified propylene emulsion, 6 parts of inorganic filler, 1 part of flame retardant, 2 parts of defoaming agent, 0.6 part of leveling agent, wetting agent 1.5 parts, 14 parts of deionized water;

[0054] The waterproof coating is made by the following steps:

[0055] The first step is to add deionized water into the container, add wetting agent, half of the defoamer, flame retardant and inorganic filler in sequence under 200r / min uniform stirring state, transfer to the ball mill and mill at 120r / min for 60min;

[0056] The second step, transfer the ball-milled mixture to the container again, adjust the speed to 800r / min, add the modified propylene styrene emulsion, stir for 20min, add the remaining defoamer and leveling agent, continue stirring for 30-40min, then use 400 Mesh filter.

Abstract

The invention discloses a waterproof coating for the surface of wooden furniture. The waterproof coating is prepared from the following raw materials: in parts by weight, 50-60 parts of a modified styrene-acrylic emulsion, 4-6 parts of inorganic filler, 0.8-1 part of a flame retardant, 1-2 parts of a defoamer, 0.5-0.6 part of a leveling agent, 1-1.5 parts of a wetting agent and 10-14 parts of deionized water. The invention also discloses a preparation method of the waterproof coating. The modified styrene-acrylic emulsion is adopted as a film-forming material for the coating, a styrene-acrylicemulsion is modified by polysiloxane, and therefore the obtained film-forming substrate not only has excellent waterproof performance, but also has heat resistance and bacteriostasis; through addition of the flame retardant which is a compound to the coating, the flame retardant properties can be developed from gas phase dilution, catalytic carbonization and different aspects, so that the coatinghas a good effect of flame retardancy; and then the waterproof coating with flame retardancy and bacteriostasis is prepared through auxiliary preparation of other additives, and is suitable for the wooden furniture, and the service life of the wooden furniture is improved.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, in particular to a waterproof coating for wooden furniture surfaces and a preparation method thereof. Background technique [0002] Wooden furniture is furniture made of solid wood, which has the advantages of being beautiful and natural and environmentally friendly. However, wooden furniture is made of solid wood sawn timber or solid wood boards as the base material, which is easy to rot in a humid environment. Apply a layer of protective material. In the past, tung oil and other drying oils, raw lacquer and nitro lacquer were mostly painted, but now they have transitioned to various synthetic resins, mainly solvent-based alkyd resin coatings, polyurethane coatings and nitro coatings, but these coatings have high solvent content. The pollution of the environment is relatively large. With the requirements for environmentally friendly products, water-based coatings have been develope...
