The characteristics and application of plastic reinforcing modifier

I. Introduction

jl-g01 modifier uses special chemical synthesis technology and functional composite technology to graft organic functional groups with chelating ability onto surfactant molecules. Therefore, the product integrates coupling agents, high-efficiency activators, processing aids and other functions. JL-G01 modifier is directly added in the processing of polyvinyl chloride (PVC) plastics. Jinan new era assay instrument Co., Ltd. has analyzed the internal structure of the experimental machine, which can not only make the inorganic filler highly dispersed, increase the amount of filler, but also improve the compatibility of each component of the system, promote plasticization, reduce melt viscosity, improve processing fluidity, and improve production efficiency. The products can be widely used in the processing of PVC plastic hard and soft products, such as plastic profiles, pipes, plates, conveyor belts, artificial leather, sealant strips, wires and cables and other polymer composites. It can also be used for surface activation modification of inorganic fillers, such as surface treatment of calcium carbonate, talc powder, mica powder, wollastonite, kaolin, aluminum hydroxide, magnesium hydroxide, etc

II. Application effect

1. It has a strong affinity for inorganic fillers, so that they can be fully activated and modified, destroy and prevent the aggregation of inorganic substances, so as to be more evenly dispersed into the polymer complex. Therefore, it can increase the amount of fillers, and rely on strong interfacial bonding to achieve the effect of toughening and strengthening

2. according to the industry, it can be used in the processing of UPVC profile, pipe and other hard products to improve the compatibility of each component of the system, promote plasticization, reduce melt viscosity, improve processing fluidity, reduce paste phenomenon and improve production efficiency. In the processing of UPVC profile, it can also improve the cold punching strength and surface properties of products, and improve the corner welding strength and elongation at break of products

3. When applied to the processing of soft products such as PVC cable materials and artificial leather, it can reduce the viscosity of the system, promote plasticization and improve the processing fluidity, so it can greatly increase the amount of filler, and at the same time, it can also improve the tensile strength, toughness and surface gloss of products

4. Used for PVC transparent or translucent pipes, plates, sheets, films, etc., it can effectively improve the compatibility and processability of the system, improve stability and whiteness, promote plasticization, improve impact strength, and increase weather resistance and aging resistance

III. technical index

l appearance: white, light yellow paste or wax

l melting temperature: no less than 40 ℃

l decomposition temperature: ≥ 260 ℃

l solubility: it is heated and dissolved in acetone, ethanol and other organic solvents, and this product is non-toxic

IV. usage

polyvinyl chloride (PVC) is added together with other additives when processing mixtures. According to the amount of inorganic filler, generally 0.20 - 0.50 parts of modifier are added per 100 parts of PVC resin (if the amount of filler is large, the amount should be appropriately increased). The processing technology bar is basically unchanged to get explosive big data pieces

when used to treat inorganic fillers, add 1.5 - 2.0% of the weight of fillers, and mix at high speed above 80 ℃ for 8 - 10 minutes

v. packaging and precautions

1. Plastic barrel packaging, net weight of each barrel 25kg, 50kg or composite bag packaging, net weight of each bag 25kg

2. pay attention to the production batch number, the best storage period is two years, put it in a dry place, sealed and protected from light (slightly purplish red does not affect the use)

the Ministry of industry and information technology has established a batch of upstream and downstream cooperation mechanisms in the fields of marine steel, electrical steel, civil aircraft aluminum and so on:
