This kind of plasticine has poor adaptability to temperature differences. It is hard to pinch in winter, and it is easy to stick to hands in hot summer. Moreover, various raw materials in its formula will volatilize toxic substances, pollute the environment, and harm the body; It is replaced by non-toxic and harmless flour plasticine, but after using this flour plasticine for a period of time, the moisture in the plasticine will evaporate, causing the plasticine to crack, harden and deteriorate, and cannot be repeated. Use; At present, in order to overcome the defects of the above-mentioned flour plasticine, a plasticine made of flour, glutinous rice flour, honey, glycerin, wheat starch, preservatives, pigments, salt, sodium benzoate, water, etc. has been proposed to prevent plasticine The product is cracked and hardened, but there are still problems of cracking and deterioration in actual use. It cannot be used repeatedly in the classroom, and there are also defects that easily cause bacteria to multiply and produce toxic substances. Some plasticine products are directly Adding chemical sterilizing agents not only has unsatisfactory sterilizing effect, but it is more likely to cause mildew of plasticine products, which will affect the health of teachers and students; some manufacturers have added a large amount of chemical pigments in order to make the plasticine bright, so that Further aggravating the health damage to teachers and students
At the same time, when using the above formula to shape English letters, there are still defects such as difficult demoulding, easy molding, and difficult inversion. After the plasticine letter handicraft is made, the letter is easy to soften, causing the letter to deform. The upper adhesion is not strong enough to demonstrate splicing on the blackboard

The special handwork plasticine for English course is prepared from the following raw materials in parts by weight: 30 parts of resin clay, 10 parts of pectin, 0.5 part of bone glue, 5 parts of aloe gel, 40 parts of modified corn starch, 10 parts of glutinous rice flour, 5 parts of neodymium iron boron magnetic material powder, 3 parts of almond oil, 1 part of palm oil, 1 part of chamomile essential oil, 0.2 part of pericarpium granati extract, 0.5 part of refined salt, 3 parts of calcite powder, 20 parts of flour, 0.5 part of calcium stearoyl lactylate, 0.2 part of sodium tripolyphosphate, 0.2 part of polymethylphenyl siloxane liquid, 5 parts of kieselguhr, 0.5 part of food coloring and 10 parts of water. In the invention, the English characters or words to be learned are shown on the blackboard in forms of plasticine characters so as to enhance the teaching interestingness and realize the characteristics of environmental protection, no toxin, harm or crack, antibacterial property, good forming property, moderate hardness and convenience in demoulding.
Description
technical field [0001] The present invention relates to a special manual plasticine for English courses, which is made into manual plasticine letters and pasted on the blackboard by making English letters or words that need to be recognized during English teaching in schools or kindergartens, thereby enhancing the fun of teaching. and its production method. Background technique [0002] Now schools and kindergartens have manual courses, and many companies provide plasticine materials to schools or kindergartens for teaching use. However, traditional clay, plasticine, is generally based on paraffin, rubber, and polyvinyl chloride paste resin. Add a lot of plasticizers, such as dibutyl phthalate or dioctyl phthalate, petrolatum. This kind of plasticine has poor adaptability to temperature differences. It is hard to pinch in winter, and it is easy to stick to hands in hot summer. Moreover, various raw materials in its formula will volatilize toxic substances, pollute the envir...
