example 1

[0075] The water-soluble ultralight clay provided by the invention is prepared by the following steps:

[0076] 1) Add 19g of PVA to 63g of water, stir the mixture and heat it at 90-98°C for about half an hour, then add 2g of sodium hexametaphosphate until the PVA forms a clear and transparent colloid;

[0077]2) Add 4.6g (artificial resin) hollow microspheres to the colloid, add 0.4g polyoxyethylene and 8g wetting agent to make it completely mixed;

[0078] 3) In order to improve the stability of the obtained composition, 3 g of additives, including colorants and preservatives, can also be added to the above-mentioned semi-finished product.

[0079] The water-soluble clay composition prepared in this example has the characteristics of ultra-light weight, non-toxic, non-sticky, good toughness, smooth surface, not easily deformed, good hand feeling and good stability.

example 2

[0081] Compared with Example 1, this example is the same except for the change of sodium hexametaphosphate in step 1: In this example, the sodium hexametaphosphate is replaced by sodium tripolyphosphate.

[0082] What can be obtained in this embodiment is an ultra-light clay composition with very poor hand feeling and stickiness.

example 3

[0084] Compared with the foregoing example 1, this embodiment also only has the change of sodium hexametaphosphate in step 1, and the other steps are the same: in this embodiment, the addition of the sodium hexametaphosphate is 1% of the composition ratio , correspondingly adjust the addition of described water simultaneously, compare the addition of sodium hexametaphosphate in the best embodiment and increase the addition of water.

[0085] Compared with Example 1, this example obtains an ultra-light clay composition that is slightly sticky to the hand, easy to mold and has better other properties.

Abstract

The present invention relates to a water-soluble clay composition and a preparation method thereof. The clay composition comprises polyvinyl alcohol, water, sodium hexametaphosphate, polyoxyethylene, a wetting agent, hollow micro-beads, and other components. The preparation method comprises: adding polyvinyl alcohol to water according to a predetermined ratio, carrying out stirring heating for about 0.5 h on the mixture at a temperature of 90-98 DEG C until a transparent colloidal material is formed, adding sodium hexametaphosphate, polyoxyethylene, a wetting agent and hollow micro-beads with a particle size of 5-60 mum to the transparent colloidal material, and completely and uniformly stirring to obtain the finished product. The water-soluble clay composition has characteristics of ultra-light weight, high quality, no toxicity, no stickiness, excellent toughness, smooth surface, deformation resistance, good hand feeling, easy operation and good stability, and is suitable for extrusion of various modeling.

Description

technical field [0001] The invention belongs to the field of modeling clay as a handicraft material, in particular to a water-soluble clay composition and a preparation method thereof. Background technique [0002] Prior art has various clay or plasticine as handicraft modeling material, as U.S. Pat.No. The function of weight, and the plasticine obtained by this scheme also has multiple superior properties such as enhanced durability, elasticity, not easy to break, and shrinkage in the drying process is greatly reduced. However, gelling agents such as borax or other boron-containing chemical reagents are also used in this water-soluble plasticine, and these chemicals will be highly toxic if swallowed. In order to prevent accidental ingestion, this plasticine is not suitable for children. And because it contains toxic ingredients, it should not be widely used as handicrafts. Chinese Patent No. ZL200910104830.8 and the corresponding U.S. Pat. No. 7,897,659 also disclose a wa...
