Description

Technical Field

[0001] The invention relates to the field of coatings, and in particular to a scorch paste for wood crafts and a preparation method and a use method thereof. Background Art

[0002] Handicrafts include wood carving, painting, knitting, clay, fabric art, etc. It is an activity that combines art, education, and psychological healing. It has important value and significance for both individuals and education. Through wood carving, children can learn the ability to observe, imagine, create, and actually operate. The crafts they make can also be used as decorations.

[0003] DIY carbonization pattern decoration on the wood surface requires easy coating, simple operation, safety and non-toxicity, short carbonization time, and the pattern cannot be deformed during the carbonization process. At present, the methods for carbonizing the wood surface include high temperature method and concentrated sulfuric acid dehydration carbonization method. For example, the high temperature method is to form a carbonized layer by keeping warm at high temperature in a carbonization kiln for a certain period of time. This method requires specific equipment, has a complex process and a long carbonization time, and is not suitable for handicrafts decorated with DIY patterns. In addition, the concentrated sulfuric acid dehydration carbonization method is to apply concentrated sulfuric acid on the wood surface, and then heat the wood surface layer to dehydrate and form a carbonized layer. This method is convenient for DIY pattern making on the wood surface, but the pattern is easily deformed during the heating process, and concentrated sulfuric acid is highly corrosive and easily causes harm to the human body, which is also not suitable for handicrafts decorated with DIY patterns.

[0004] In summary, how to prepare a jiaoji paste that is easy to apply, simple to operate, safe and environmentally friendly, has a short carbonization time, and can solidify during the carbonization process is a current technical challenge. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a carbonized paste for wood craft and a preparation method and a use method thereof, which has the advantages of short carbonization time, easy coating, simple operation, safety and environmental protection.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] A charcoal paste for wood crafts comprises: 1-40wt% of a surfactant, 10-60wt% of a thickener, 3-40wt% of a carbonizing agent, 20-60wt% of a solvent and 1-3wt% of a preservative; the carbonizing agent comprises 1-40wt% of a phosphoric acid flame retardant, 0-30wt% of a sulfate compound, 5-60wt% of a ferric ion / ferrous ion compound and / or 3-50wt% of a phosphoric acid metal compound.

[0008] The charcoal paste for wood craft of the present invention can be used for DIY handmade wooden board decoration. The charcoal paste for wood craft includes a carbonizing agent containing 1-40wt% of phosphoric acid flame retardant, 0-30wt% of sulfate compound, 5-60wt% of iron ion / ferrous ion compound and / or 3-50wt% of phosphoric acid metal compound. Phosphoric acid flame retardant is an important class of organic phosphorus flame retardant, which decomposes at high temperature to form phosphoric acid or polyphosphoric acid. These compounds act as dehydrating agents to promote dehydration and carbonization of the polymer surface to form a stable carbon layer. Phosphoric acid metal compound and phosphoric acid flame retardant can produce a synergistic effect, which can promote the formation of carbon layer, enhance the stability of carbon layer, and improve the compactness of carbon layer. In addition, iron ion and ferrous ion compounds as inorganic flame retardants can produce a synergistic effect with phosphoric acid flame retardant, iron ion can promote the cross-linking of polymer and the formation of carbon layer, and ferrous ion can act as a reducing agent to participate in pyrolysis reaction, reduce the thermal decomposition temperature of polymer, thereby acting together with phosphoric acid flame retardant to promote dehydration and carbonization to form a more stable carbon layer. When the content of the carbonizing agent is less than 3wt%, the carbonization intensity is small, the carbonization time is long, and it is difficult to form the desired painting effect; when the content of the carbonizing agent is greater than 40wt%, it is not easy to form an ideal paste-like state that is easy to apply, it is easy to agglomerate and precipitate, and the cost is relatively high. In addition, controlling the content of surfactants, thickeners, and solvents within the above range is conducive to the formation of an ideal viscous state of the Jiaoji paste for wood crafts, which is easy to adhere to the wooden board. The Jiaoji paste described in the present invention has low production cost, simple and feasible preparation process, and has the characteristics of excellent carbonization effect, high safety, high storage stability, non-toxic and environmentally friendly, easy to apply, and little pollution to the environment. It can be used for DIY handmade wooden board decorative patterns, and can also be used for carbonization of wood surface for insect prevention, flame retardancy and anti-corrosion.

[0009] Furthermore, the phosphoric acid flame retardant is selected from at least one of phosphoric acid, phosphorous acid, polyphosphoric acid, diammonium phosphate, red phosphorus, polyphosphate amine, phosphamide, and tricresyl phosphate; the phosphoric acid metal compound is selected from at least one of iron phosphate, ferrous phosphate, lithium iron phosphate, cobalt phosphate, aluminum phosphate, yttrium phosphate, potassium phosphate, barium phosphate, sodium phosphate, magnesium phosphate, molybdenum phosphate, and zirconium phosphate; and the iron ion / ferrous ion compound is selected from at least one of ferric chloride, ferrous chloride, ferric chloride hexahydrate, ferric sulfate, and ferrous sulfate.

[0010] The sulfate compound is selected from at least one of ammonium sulfate, ammonium persulfate, ammonium sulfite, ammonium persulfate, ammonium thiosulfate, ammonium ferric sulfate, and ammonium hydrogen sulfate. The sulfate compound helps to form a stable carbon layer on the surface of the polymer. The sulfate compound is used in combination with a phosphoric acid flame retardant to achieve a better flame retardant effect.

[0011] Furthermore, the surfactant is selected from at least one of monoglyceride, succinylglycerol monoester, sucrose fatty acid ester, Span-80, Tween-80, propylene glycol fatty acid ester, lauric acid and soybean lecithin.

[0012] Furthermore, the thickener is selected from at least one of starch, gum arabic, pectin, agar, gelatin, sodium starch phosphate, glutinous rice flour, sodium carboxymethyl cellulose and polyvinyl pyrrolidone.

[0013] Furthermore, the solvent is selected from at least one of water, ethanol, n-propanol, isopropanol, propylene glycol and the like.

[0014] Furthermore, the preservative is selected from at least one of benzoic acid, sodium benzoate, sorbic acid, potassium sorbate, and hydroxybenzoic acid esters.

[0015] A method for preparing a Jiaoji paste for wood crafts comprises the following steps: uniformly dispersing the surfactant, the thickener, the carbonizing agent and the preservative into the solvent at a certain temperature, heating to a certain temperature and reacting for a certain time to make it into a viscous paste, and cooling to room temperature to obtain the Jiaoji paste for wood crafts.

[0016] Furthermore, the dispersion temperature is 10-50°C; the heating reaction temperature is 60-140°C; and the reaction time is 0.1-3 hours.
