Problems solved by technology

As we all know, toys are mostly made of plastic. However, plastic toys in the prior art, due to the use of stabilizers, plasticizers, crosslinking agents, etc. in the production process, are abandoned after damage and cannot be degraded, which is extremely harmful to the environment. Therefore, it is necessary to develop a degradable plastic material to make toys and reduce the harm to the environment

preparation example Construction

[0016] A preparation method for a novel environment-friendly material for toy manufacture, comprising the following steps:

[0017] (1) Use a grinder to grind the rice husk into 420-450 purpose tiny grain rice husk powder;

[0018] (2) Add rice husk powder into a high-temperature high-speed mixer, then add cellulose, polylactic acid, talcum powder and calcium carbonate in sequence and mix evenly, inject 50-80 parts by mass of water during the mixing process, and then take it out and cool it;

[0019] (3) Stir and mix the materials in step (2), natural resin, polyvinyl alcohol, food coloring, polyethylene and photodegradant evenly at room temperature, and then extrude at an extrusion temperature of 120-160° C. for 3 minutes.

Embodiment 1

[0020] Embodiment 1: A new type of environmentally friendly material for toy manufacturing and its preparation method, including the following raw materials in parts by weight: 17 parts of rice husk, 22 parts of cellulose, 36 parts of natural resin, 16 parts of polylactic acid, and 7 parts of polyvinyl alcohol , 1.5 parts of talcum powder, 0.8 part of food coloring, 16 parts of calcium carbonate, 20 parts of polyethylene and 0.6 part of photodegradant; the calcium carbonate is heavy calcium carbonate.

Abstract

The invention discloses a novel environment-friendly material for toy manufacturing and a preparation method. The degradable non-toxic environment-friendly toy material is prepared from the followingraw materials in parts by weight: 10 to 18 parts of rice husk, 20 to 25 parts of cellulose, 30 to 38 parts of natural resin, 10 to 16 parts of polylactic acid, 5 to 9 parts of polyvinyl alcohol, 1 to3 parts of talcum powder, 0.5 to 0.8 part of edible pigment, 10 to 16 parts of calcium carbonate, 15 to 20 parts of polyethylene and 0.4 to 0.8 part of light degradation agent. The degradable non-toxic environment-friendly toy material prepared by adopting the formula and the method has the characteristics of being non-toxic and environment-friendly, can be biodegraded and photodegraded, can become an organic fertilizer after being degraded, returns to nature, is moderate in hardness and density, does not change color, mildew, shrink, embrittle, crack and deform, and is very suitable for manufacturing toys.

Description

technical field [0001] The invention relates to the field of toy manufacturing, in particular to a novel environment-friendly material for toy manufacturing and a preparation method. Background technique [0002] With the development of science and technology and the progress of society, people's purchasing power and desire to buy are gradually increasing, and the amount of toys that adults buy for children is also gradually increasing. As we all know, most of the toys are made of plastic. However, due to the use of stabilizers, plasticizers, cross-linking agents, etc. in the production process, plastic toys in the prior art are abandoned after damage and cannot be degraded, which is extremely harmful to the environment. Therefore, it is necessary to develop a degradable plastic material to make toys and reduce the harm to the environment. Contents of the invention [0003] According to the deficiencies of the prior art, the present invention provides a novel environment-...
