Description

A method of making salt carving

Technical field

The invention belongs to craftwork manufacturing fields, and in particular to a kind of preparation of salt carving handicraft article.

Background technique

Modern salt carves the art work, typically directly obtains saturated bittern using the outer solarization of the brine chambers such as seawater, then be concentrated crystallization, Engraving moulding, colouring etc. are prepared, by taking TW200844051A as an example, during solarization, and chlorine contained in saturated bittern Change sodium and persistently crystallize precipitation, is crystallized according to mold shape, finally obtain salt carving handicraft article.In the actual production process, Shen It asks someone to find, there are many defects for outdoor solarization: 1, outdoor solarization is easy the inclusion of dirt in crystallization process, leads to scrap of the product Rate is higher, and 2, solarization temperature and illumination condition are closely related, and solar temperature is low, and crystallization speed is slow, and crystallization is uneven, production efficiency It is low.

A kind of method for preparing salt carving substrate is disclosed in CN102218963A, directly with dry salt grain and asphalt mixtures modified by epoxy resin Rouge is raw material, and salt carving substrate is prepared by processes such as vacuum defoamation, forming, surface cleans.It is disclosed in CN102417322A Salt fines and resin, methyl ethyl ketone peroxide, cobalt iso-octoate etc. are mixed, film-forming prepares the scheme of salt carving, main purpose It is to solve the problems, such as salt carving dampness, Yi Ronghua, not easy to maintain.A kind of salt carving coating, public involved in CN107523184A The process sprayed on salt carving surface has been opened, coating is made of epoxy resin and curing agent mixing, wherein it is not disclosed how Salt carving crude product is prepared, only discloses last spraying process.

During directlying adopt the progress salt carving production of the brine such as seawater, inventors have found that even across the behaviour such as spraying To make, obtained salt carving handicraft article still will appear the defect of discoloration after placing a period of time, significantly reduce ornamental value, For this problem, corresponding solution is not provided at present in the prior art.

Summary of the invention

Defect present in method for existing production salt carving, inventor are raw material to provide one kind by salting liquid, The new process of salt carving is prepared by filtering, chelating the processes such as removal of impurities, concentration, moulding, demoulding, this method does not need additionally in salt It is the discoloration problem that can effectively avoid subsequent product that the reagents such as fluorescent whitening agent, which are added, the salt carving works holding time being prepared Long, ornamental value is high, and product rejection rate is greatly reduced in production process, high production efficiency, and economic value is high.

The solution of the present invention is specifically:

Step 1, it configures saline solution in dustless factory building and stirs and be fused to saturated solution, filter；

Step 2, chelating agent is added into the saturated solution of step 1, stirring to precipitating occurs, filtering；

Step 3, the heating of step 2 acquired solution is concentrated into paste, is injected in mold after being mixed with resin and curing agent, solidification modeling Shape；

Step 4, it demoulds, drying, polishing, modification corner, polishing obtain finished product until product is smooth.

Wherein it is preferred to salt described in step 1 concretely sea salt, rock salt, well salt, lake salt and rock salt and industrial tail salt One such or several combination configures, and stirring and dissolving is crossed and filtered out to being saturated in 55 DEG C to 65 DEG C of deionized water Remove the insoluble impurities such as silt.Wherein the industrial tail salt is one of trade waste, is carried out again to trade waste sharp Be country encourage and policy guidance.By industrial tail salt be used to produce salt carve for salt carving production provide new thinking, reduction Environmental pollution, imparts new economic value.The industry tail salt can be the reverse flotation tail salt generated in potassium fertilizer production process, When selecting the industry tail salt is raw material, increase calcining, dissolution, the operation of crystallization before step 1.Specifically, tail salt is placed in In nonmetallic vessel, 15-40min is calcined at 400-600 DEG C, and deionized water is added and dissolves by heating, is filtered to remove not after standing Molten object obtains salt grain after taking clarified solution to be concentrated by evaporation.

Preferably, chelating agent described in step 2 is that citric acid, EDTA etc. can form flocculate with non-ferrous metals such as iron, copper Chelating reagent, preferably citric acid, on the basis of sodium chloride, the molar ratio of salt and chelating agent is 1:0.1-0.5, preferably 1: 0.3-0.5.By chelation, non-ferrous metal is removed from salting liquid, it is possible to prevente effectively from what subsequent finished product changed colour Problem extends the ornamental service life of craftwork.

Preferably, electric heating, heating water bath or steam heating, heating temperature are heated to be in step 3 and is not higher than 100 DEG C, is satisfied Stop heating when being lower than 10-50% with the moisture specific gravity in solution.Wherein preferred heating temperature is 50-90 DEG C, more preferable 60-70 DEG C, moisture specific gravity is preferably shorter than 10-30%, more preferably less than 10-15%.The resin include but is not limited to epoxy transparent resins, Acrylic resin etc., preferred epoxy.The curing agent includes but is not limited to aliphatic polyamine, alicyclic polyamine, phenolic aldehyde, acid Acid anhydride etc..Preferably, increase vacuum defoamation after injecting mold, to remove the vacuole in mixture.

Preferably, optionally increase color drawing for curved surface of body step after obtaining finished product, carve surface coating color in salt, it is preferably sharp It is painted with transparency dye spraying, is painted relative to general paint application, transparency dye spraying colouring can make colouring more Uniformly, bright, it is not easy decoloration for a long time and fades away.

The salt carving handicraft article that the technique provided according to the present invention is prepared, raw material sources are extensive, production process is simple, at Product rates is high, not easy to change, watches that the service life is long, value is high, and homogeneous, engraving property is good, overcome traditional salt carving be easy discoloration, at The problems such as product rate is low has splendid prospects for commercial application.

Specific embodiment:

Embodiment 1:

Step 1, it in dustless factory building, takes commercially available sea salt that deionized water dissolving is added and obtains saturated solution, filtering removal silt etc. Insoluble matter；Step 2, the above citric acid of 95% purity is added into the saturated solution of step 2, stirring to precipitating occurs, and filtering takes Clarified solution；Step 3, step 3 acquired solution being heated at a temperature of 60-70 DEG C using steam and is concentrated into paste, moisture is lower than 8%, It injects in mold, vacuumizes after being sufficiently stirred with epoxy resin and curing agent M50, pressurization solidification moulding；Step 5, it demoulds, dries Dry, polishing, modification corner, polishing obtain finished product until product is smooth.
