preparation example Construction

[0056] Correspondingly, the preparation method of this bamboo clay specifically comprises the following steps:

[0057] 1) According to the mass ratio of water: polyvinyl alcohol of 4:1-3:1, add polyvinyl alcohol into water, stir and heat the mixture at a temperature of 85-95°C to form a transparent polyvinyl alcohol paste body;

[0058] 2) Add natural cellulose powder to the paste, and stir to make it fully wet; in order to improve the quality of the mixture, add wetting agents and additives to the above paste;

[0059] 3) Dissolve sodium tetraborate with a certain amount of water at about 75°C, slowly add sodium tetraborate solution to the mixture in step 2 while stirring, and continue stirring until it is completely mixed and does not stick to hands.

[0060]The invention is a water-soluble product made by using boric acid as the cross-linking agent of PVA. The bamboo clay made by the invention has strong plasticity, is easy to shape, and the surface can be colored; Hand,...

example 1

[0063] In this example, the recipe for bamboo clay is:

[0064] Polyvinyl alcohol 13g

[0065] Natural Fiber Powder 30g

[0066] Sodium tetraborate 1.5g

[0067] Wetting agent 5g

[0068] Additive 1.5g

[0069] 66g of water.

[0070] The concrete manufacture method of bamboo clay comprises the following steps:

[0071] First, add 13g of PVA to 51g of water, mix and stir it and heat it at 85-95°C for about one hour until the PVA forms a transparent pasty colloid;

[0072] In the second step, add 30g of natural fiber powder to the above-mentioned pasty colloid, the natural fiber powder can be selected with a mesh number of about 150, and stir well;

[0073] The 3rd step, in order to improve the quality of mixture, add wetting agent 5g in above-mentioned semi-finished product, as glycerol, sorbitol, propylene glycol etc., and the additive of 1.5g, comprise antiseptic, bittering agent etc., thereby make composition reach high density stage;

[0074] The fourth step is to d...

example 2

[0076] In order to better reflect the impact of the borax on the performance of the composition and the environmental protection of the product of the present invention, the present invention also provides two groups of comparative experiments:

[0077] The first group: this experiment is compared with above-mentioned embodiment one, and its only difference is in the 4th step, and in the 4th step we will see that along with adding gradually of borax solution, above-mentioned composition will be by very Sticky hands gradually become non-sticky, but if the quantity exceeds the limit, the product will be plasticized, so the quantity of borax will directly affect the quality of the product.

[0078] The second group: In the biodegradation test comparison, the "oily clay" on the market and the product of the present invention are buried in the soil at the same time. After a few months, we will see that the oily clay still exists in the soil, while the product of the present inventio...

Abstract

The invention relates to bamboo clay, which comprises polyvinyl alcohol, cellulose powder and sodium pyroborate. A preparation method of the bamboo clay mainly comprises the following steps of: adding polyvinyl alcohol into water in the mass ratio of 3:1-4:1, and stirring and heating the mixture to form transparent polyvinyl alcohol pasty cream; adding cellulose powder into the cream, and stirring till the cellulose powder is fully wetted; dissolving the sodium pyroborate with water, and slowing adding a sodium pyroborate solution under the stirring condition; and continually stirring till the components are fully mixed and are not sticky to hands. The bamboo clay disclosed by the invention has the advantages of safety, environmental friendliness, flexibility, stretchability, difficulty in cracking after being dried, light weight after being dried, high shaping performance, safety for using, readily-available raw materials, low cost and the like, and is suitable for children or artists.

Description

technical field [0001] The invention belongs to the field of water-based plasticine or clay Modeling Dough or Clay as a handicraft material, in particular to a bamboo clay and a preparation method thereof. Background technique [0002] In the prior art, there are many plasticines or clays as handicraft materials, such as traditional oily clay, starch-filled plasticine, etc. However, there are many deficiencies in the product, which limit its application in some aspects due to its non-air-drying characteristics. For example, shapes made with this oily clay don't dry out, are difficult to preserve, and have poor durability. However, starch-filled plasticine has the disadvantages of being easy to crack and heavy after drying, and easily broken when dropped. [0003] The main filling material of oily clay seen on the market is "hollow microspheres". Toxic or narcotic; (2) The biodegradability is extremely poor, which seriously damages the soil structure; (3) The shape is diff...
