A kind of fully degradable biological material polymerization production equipment and production method thereof

Abstract

The invention discloses a fully degradable biological material polymerization production equipment and a production method thereof in the technical field of fully degradable biological material polymerization production. The top of the mixing cylinder is fixedly connected with a lowering material cylinder, the top of the lowering material cylinder is fixedly connected with a drying cylinder, and the middle of the drying cylinder is rotatably connected with a rotating shaft; When mixing, the four materials that need to be dried are dispersed and mixed while being dried, so that the four materials can be in a dispersed and mixed state when they are in a solid state, avoiding material accumulation, which is more conducive to rapid mixing of materials, and the use of cones. The rotating shell, the first annular partition plate and the second annular partition plate separate and layer the materials for mixing, and cooperate with the blocking plate and the two sealing plates to mix the materials in the forward and reverse directions, so that the four materials can be mixed evenly. Faster even mixing.

Description

technical field [0001] The invention relates to the technical field of fully degradable biological material polymerization production, in particular to a fully degradable biological material polymerization production equipment and a production method thereof. Background technique [0002] Blending polylactic acid and poly(butylene terephthalate-co-butylene adipate) ester, taking advantage of the complementary performance advantages of the two, and adjusting the blending ratio of the two, not only can a higher strength copolymer be obtained. The blend can also improve the flexibility of the blend. The film prepared by using the blend can achieve full biodegradation and is an environmentally friendly material. [0003] The prior art discloses an invention patent for the polymerization production of partially fully degradable biomaterials. The Chinese patent with the patent application number CN201210297866.4 discloses a fully biodegradable PLA / PBAT composite material and a pre...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of fully degradable biomaterial polymerization production equipment and production method thereof, to solve the problems in the prior art in the prior art of polylactic acid, polyester, thermoplastic starch and compatibilizer A, B and When the filler is mixed, the mixed materials are gathered together and added to the mixing cylinder. Each material is piled up into a pile and falls into the mixing cylinder. When thermoplastic starch and other materials are mixed with water, they will condense into small particles, resulting in material mixing. The difficulty of uniformity is greatly increased. It takes a long time to mix and stir the materials to make some materials fully and evenly mixed, which leads to longer processing time and affects the processing efficiency.
