Preparation Of Strong Polar And High-Deformation PVC Gel And Design Of Actuator Model

PVC(polyvinyl chloride)material is one of the most widely used raw materials in the plastics processing industry in the world.Due to its excellent chemical properties,and cheap and easy preparation,it is widely used in daily production and is one of the important raw materials in the field of chemical synthesis.Due to its excellent chemical stability,insulation,transparency,mechanical properties,and corrosion resistance,PVC materials are widely used in industrial production,insulation coatings,and soft or hard household products.In recent years,researchers have focused on the plastic modification of PVC materials.Due to the large number of C-Cl-dipole moments inside the PVC molecules,the materials have strong polarity.Inorganic non-metallic soft materials used in electro-actuated response have been found to have a wide range of application prospects such as:biomimetic engineering,flexible electronics,software robots,etc.The prepared PVC soft material has good mechanical properties and durability,and also shows its advantages over other soft materials under the effect of electrical stimulation.This paper first analyzes the research progress of soft materials in the field of soft robots in the research progress at home and abroad,and then combs and analyzes the research status of PVC gel materials,and improves the polarity of PVC,from process improvement,material modification and model design.In terms of research on PVC gel:(1)In view of the problem of process improvement,the research found that in the exploration of PVC gels used in optical products,the commonly used process of preparing PVC gels often has insufficient dissolution,poor preparation materials,poor surface roughness,poor light transmission,etc.For this problem,combined with the theoretical support of molecular thermal motion,the research starts with the optimal use temperature of the raw materials,and discusses the different stirring temperatures(40℃-70℃,temperature gradient 10℃)in the preparation of PVC gel.It is concluded that the reaction temperature can make the cross-linked system more uniform,which in turn affects the material properties.After that,the molded PVC gels were tested in groups,including mechanical properties,surface characteristics,transparency,etc;studies have shown that 60℃ is an optimal reaction temperature point,and the performance of the prepared gels is the best.Above or below 60℃,the performance of the material has declined in varying degrees.The response time and recovery time of the gel and varifocal microlens were nearly doubled compared with previous studies.(2)In view of the material modification problem,the DC voltage of the existing driving PVC gel is still very high(from 200V to 1500V),and the energy consumption is high for experimental exploration.To solve this problem,the study added polarity.The stronger carboxylated nanocellulose can improve the conductivity of the material,and can be driven with a lower voltage within the same degree of electrical stimulation deformation.The formed gel with nanocellulose was analyzed and tested,and the response time and deformation effect at the same voltage were tested under the measurement of the laser displacement collector with the help of the experimental model of the multilayer film structure.The nanocellulose can improve the electrical conductivity and mechanical properties of the material,which is equivalent to reducing the driving energy consumption and shortening the response time.During the test,it was found that trace amounts of nano-cellulose had a certain effect on the transparency of the gel material.At the same time,because the experiment involves the use of hazardous chemicals,this article also conducts a hazard analysis of the raw materials used and suggestions for emergency measures.(3)For the model design,the study summarizes the existing PVC gel actuation model,summarizes its existing performance and structural deficiencies,and according to the experimental phenomenon,it is known that most of the electric actuation models are powered off.After the recovery hysteresis,it is proposed to use additional elastic force(spring)to improve the model recovery time after energization contraction.Through the connection of the drive circuit and the relay,the deformation in a single direction is controlled,so that the drive module can achieve multi-directional deformation under a single DC power supply.The finite element simulation analysis of the model is carried out,and the simulation results are compared with existing research conclusions,to confirm the rationality of the design.And it provides a theoretical possibility for the design of the new driver.In summary:the solution method is used to prepare the polymer composite PVC gel.In view of the problems of high driving voltage,poor transparency,and slow response time proposed by the application status,the reaction process,polarity optimization,and driving architecture were studied and improved,and excellent performance results were obtained,which accumulated data and experimental experience for the subsequent preparation of PVC gel,laid the foundation for other applications of PVC gel,and provided technical support.
