A kind of salt carving raw material and preparation process

Abstract

The invention relates to a salt sculpture raw material and a preparation process thereof. The salt sculpture raw material and the preparation process are characterized in that: the raw material comprises 95-99 parts by weight of sea salt, 0.5-3 parts by weight of alpha-cyanacrylate glue, and 0.1-2 parts by weight of polyurethane; the sodium chloride content in the sea salt is higher than 99.5%; the particle size of the sea salt is lower than 0.15 mm; and the process includes adding the sea salt according to the weight part into a stainless container, adding the alpha-cyanacrylate glue according to the weight part, stirring for 30 min, adding the polyurethane according to the weight part, stirring for 20 min, pressing the mixture into a mould under a pressure of 105 Pa, placing the mould at 15-25 DEG C for 2 h, demoulding after the mixture is cured and formed, putting into a heating oven, heating at 400 DEG C for 5 h, lowering the temperature of a product taken out from the heating oven to 15-25 DEG C, and polishing artificially to obtain a salt sculpture product. According to the process, the salt sculpture product with high salt content can be obtained by adopting the sea salt as the basic raw material and adopting a small amount of other auxiliary materials. The salt sculpture product has a salt content higher than 95%, is snow white, and is fine in texture, high in moulding stability, convenient to store and long in storage time.

Description

technical field [0001] The invention relates to the technical field of sculpture, in particular to a raw material for salt sculpture and a preparation process. Background technique [0002] At present, there are many kinds of raw materials for sculpture, such as stone, wood, ice, plastic, mud, etc. All kinds of raw materials have both advantages and disadvantages in actual carving. Among many sculpture materials, salt sculpture is a new kind of sculpture Materials, salt carving products are white and elegant, calm and atmospheric, with profound cultural connotations, and are more and more popular among people. [0003] Most of the existing salt carving product preparation processes first use salty brine to make salt bricks by sunlight, and then carry out subsequent steps such as carving and coloring. In the process of salt crystallization, this process is affected by factors such as changes in brine concentration, impurities in brine, brine depth, wind direction, relative h...

AI Technical Summary

Problems solved by technology

In the process of salt crystallization, this process is affected by factors such as changes in brine concentration, impurities in brine, brine depth, wind direction, relative humidity, rainfall, water evaporation speed, crystallization rate, temperature changes, etc. The color and shape of salt bricks cannot be precisely controlled

In addition, the structure of the salt bricks produced by the above process is usually loose powder or fine blocks, and it is difficult to have a large salt block with sufficient hardness, so that it is difficult to preserve, not refined enough, difficult to paint, and even difficult to produce in large quantities.

[0004] In addition, most of the existing salt carving products are difficult to break through the technical problems that salt is easy to dissolve and difficult to shape, and in order to ensure its stability, the salt content of most existing salt carving products can only reach 50%-80%, and the rest Use a large amount of curing agent and other auxiliary materials to ensure the stability of salt carving products

If the salt content is too high, the hardness and toughness will be too poor to ensure the stability and durability of the salt carving products, but the salt content is too low and the aesthetic feeling and grade of the salt carving products will be reduced
