Problems solved by technology

[0005] The current problems of degradable plastics are mainly that they are expensive and difficult to popularize and utilize. Starch-filled plastics cannot be degraded. , Accurate degradation controllability, rapid degradability after use, complete degradability and recycling technology of leftover materials need to be further improved and perfected
Environmentally degradable polymers have not yet had a unified definition in the world and have completely established a unified test evaluation method, identification mark and product testing standards, resulting in confusion in the technology market and product market.
In addition, the current research on degradable plastics is still mainly based on the degradation of polymer resins, and most of them fail to take into account the factors of additives; except for completely biodegradable plastics, the intermediate degradation of other various degradable plastics in the degradation process The impact of the product on animals and plants has not been evaluated, etc.

Abstract

The invention discloses polyhydroxybutyrate-based degradable 3D (Three Dimensional) printing supplies. The polyhydroxybutyrate-based degradable 3D (Three Dimensional) printing supplies are prepared from the following ingredients in parts by weight: 50 to 80 parts of master batch, 40 to 80 parts of modified starch, 1 to 3 parts of pigment and 2 to 4 parts of assistant, wherein the master batch is polyhydroxybutyrate plastic; the assistant is prepared from the following ingredients in parts by weight: 10 to 15 parts of lubricant, 20 to 40 parts of plasticizer and 5 to 10 parts of antioxidant; the lubricant is one of barium stearate, fatty acid amide and glycerol monostearate; the plasticizer is one of DEHP (Di 2-Ethyl Hexyl Phthalate), DOP (Dioctyl Phthalate) and DBP (Dibutyl Phthalate); the antioxidant is an antioxidant 1010 or an antioxidant TNP (Trinitrophenol). The polyhydroxybutyrate-based degradable 3D (Three Dimensional) printing supplies disclosed by the invention have stronger mechanical property and good stability, are not easy to emit harmful substances during a using process and can be widely applied to the field of food packaging and living.

Description

technical field [0001] The invention relates to a polyhydroxybutyrate-based degradable 3D printing consumable. Background technique [0002] Degradable plastics refer to the addition of some additives to promote their degradation in plastics or the use of renewable natural raw materials, which can meet the application performance requirements during the use and storage period, and after use, under specific environmental conditions, in a short period of time Its chemical structure will change significantly over time, resulting in the loss of certain properties, or a type of plastic that has degradable properties when synthesized. Degradable plastics play a pivotal role in solving the global white pollution problem. [0003] As a multifunctional new technology material, degradable plastics have a wide range of applications and great market potential. According to relevant data, the consumption of biodegradable polymers accounted for about 2% of the total plastic consumption ...
