Problems solved by technology

[0004] While the branches are crushed, there is a lot of water in the fresh branches. When the pulverizer crushes them, the water is distributed in the shell and on the crushing roller. Some branches The sap is acidic, such as the branches of an orange tree, the sap is acidic, and the acidic sap adheres to the crushing roller, which can cause surface corrosion of the crushing roller and reduce the crushing effect of the crushing roller on the branches, resulting in insufficient crushing of some branches. Input broken, affect the production and processing effect

[0059] 2-5 parts of polyvinyl alcohol;

[0060] 3-6 parts of butyl acrylate;

[0061] Plant fibers are used as raw materials for plastics, and plant fibers can be straw fibers, tree fibers, grass fibers, etc.; branches or branches trimmed from fruit trees are generally handled in existing ways, such as crushing them, and then...

Embodiment 2

[0076] refer to Figure 6 , Comparative Example 1, as another embodiment of the present invention, wherein the base block 3 is provided with a water spray hole 25; the water spray hole 25 is connected to the external water pump of the housing 1 through a water pipe, and the water spray hole 25 is The oil delivery pipe 5 is connected through the intermediate pipe, and a one-way valve 26 is arranged in the intermediate pipe; through setting the water spray hole 25, the water spray hole 25 sprays clean water, and the clean water first impacts on the surface of the crushing roller 2 to wash away the debris adhered to the surface Then turn off the water pump, drive the oil supply pump, and spray the protective oil on the surface of the crushing roller 2 to reduce the blockage of debris on the protective oil, and carry out antirust treatment on the crushing roller 2 more comprehensively. When the oil pressure is greater than the one-way valve 26 When the threshold value is opened, p...

Abstract

The invention belongs to the technical field of plastic production, and particularly relates to fully-degradable modified plastic and a preparation method thereof.The preparation method of the fully-degradable modified plastic comprises the following steps that S1, raw materials are prepared, specifically, plant fibers with different mesh numbers are prepared, and branches are put into a pulverizer to be smashed into chippings for standby application; s2, adding the base material and the additive into a reaction kettle, heating in a water bath to 70-100 DEG C, stirring at a constant speed to react for 20-30 minutes, and carrying out low-pressure reaction; s3, after the low-pressure reaction is finished, the pressure of the reaction kettle is increased to 2.0-3.5 MPa, the temperature is increased to 100-120 DEG C, the stirring time is controlled to be 15-20 minutes under the low-speed stirring condition of 30-70 rpm, then the pressure is relieved, the vacuum degree is kept to be 0.02-0.08 MPa, and flexible lumps are obtained for standby application; s4, putting the flexible bulk into a dispersion machine, mixing and dispersing the flexible bulk in the dispersion machine, controlling the time to be 3-6 minutes, controlling the temperature to be 80-90 DEG C, then putting into a screw reaction extruder, and shearing, mixing, devolatilizing, extruding and granulating through the screw extruder to obtain the full-degradable modified plastic.

Description

technical field [0001] The invention belongs to the technical field of plastic production, in particular to a fully degradable modified plastic and a preparation method thereof. Background technique [0002] Plastic products provide many conveniences for manpower, and are widely used in any field of human activities. Compared with metal, stone, and wood, plastic products have the advantages of low cost and strong plasticity. They are widely used in the national economy. The plastic industry occupies an extremely important position in the world today. Important position, the production of plastic products has developed at a high speed all over the world for many years. [0003] The development of plastics has also brought many environmental problems. Due to the characteristics of plastics, it is difficult to be decomposed in the natural environment, pollute the environment, and be swallowed by animals in the local area, resulting in the death of animals. Plastic products are ...
