Plastic material for antioxidants
Antioxidants in plastic plastic materials should be stable, in the process of using high temperature environment and less volatile loss, don't change color or no color, no decomposition (except for the processing of the thermal stability antioxidant). The anti-oxidants of plastic materials should not react with other additives in adverse chemical reactions, and do not corrode mechanical equipment and are not easily extracted by other substances on the surface of the product. Hindered amine light stabilizer is commonly low alkaline chemicals, selection of plastic materials, hindered amine light stabilizer for should not contain in the recipe acidic other additives, the corresponding plastic products used in acid environment.
The production consumption of colorant colored plastic products accounts for more than 80% of the total consumption of plastic products. Because colorants molecules contain chemical element, chemical structure is different, different kinds of plastic colorants products not only USES, tinting strength, hiding power, coloring, weather resistance, chemical resistance character a persistence or firmly significant differences, toxicity and other main performance, but also for coloring plastics molding, machining process of the thermal stability of oxygen, light, oxygen stability of using process have an impact. Especially light, oxygen stabilization of colored plastic products, plastic colorants if cooperate with antioxidant and light stabilizer is undeserved, can cause premature coloring plastics fade or change color, but also speed up the light colored plastic products, oxygen aging.
Plastic is a monomer as raw material, through the addition polymerization and polycondensation reaction of polymerization of polymer compounds (macromolecules), commonly known as plastic (plastics) or resin (resin), free to change the style, composition and form consists of synthetic resin and packing, plasticizer, stabilizer, lubricant, ink additive composition and so on.
The main component of plastic is resin. The term resin is originally derived from the lipids secreted by plants and animals, such as rosin, shellac, etc. Resin refers to the high molecular compound that has not been mixed with various additives. Resin accounts for 40% ~ 100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of resins, but additives also play an important role. Some plastics are basically made up of synthetic resins, without or without additives, such as organic glass and polystyrene.
Plastic, in fact, is one of the synthetic resins, similar to those found in natural resins, which are chemically synthesized and called plastic.
Plastic material is defined as a synthetic or natural macromolecular compound that can be arbitrarily shaped into a material or a plastic material that can last in shape.
Triphenyl phosphite (TPPi antioxidants, stabilizer) is mainly used in PVC, polyethylene, polypropylene, polystyrene, polyester, abs resin, epoxy resin, synthetic rubber antioxidant stabilizer, used in polyvinyl chloride (PVC) products as a chelating agent, when is given priority to with metal stabilizer, cooperate with this product can reduce the harm of metal chlorides, maintain product transparency, and inhibition of color change, is also a good chemical intermediates, with phosphorus-containing flame retardant and use, can play a role of flame retardant antioxidant, and with stable performance, light can be used for synthesis alkyd resin and polyester, main raw materials for resin, this product can also be preparing pesticide intermediates trimethyl phosphite.
Most plastics are light, chemical stable, and do not rust; Good impact resistance; Good transparency and wear resistance; Good insulation, low thermal conductivity; General molding, good coloring, low processing cost; Most plastics have poor heat resistance, high thermal expansion rate and easy to burn; Poor dimensional stability and easy deformation;
Most plastics have low temperature resistance, brittle at low temperature and easy to age. Some plastics are soluble in solvents.
Plastic can be distinguished between thermosetting and thermoplastic type, the former cannot be reshaped, and the latter can be produced again. The physical elongation of thermal plasticity is large, usually between 50% and 500%. The force is not completely linear at different elongation rates.
The different properties of plastic determine its use in industry. With the improvement of technology, the research on plastic modification has not been stopped. It is hoped that in the near future, plastics will be more widely used in the future, and may even replace steel and other materials and no longer pollute the environment.
There are basically two types of plastics: the first is the linear structure, and the polymer compound with this structure is called linear polymer. The second type is the structure of the body, which is called the body polymer. Some polymers have branched chains, known as branched polymers, which belong to the linear structure. Some polymers, even though they have crosslinks between molecules, have fewer crosslinks, called reticular structures, and are in the shape of their bodies.
Two different structures show two opposite properties. Linear structure, heating can melt, hardness and brittleness less characteristic. Hardness and brittleness of body type. Plastic is a polymer of two kinds of structure, made of linear polymer is thermoplastic, made of body type polymer is thermoset plastic.
The plastic we usually use is not a single component, it is made of many materials. One polymer (or synthetic resin) is the main component of plastic, in addition, in order to improve the performance of the plastic, and add all kinds of auxiliary materials in the polymer compounds, such as packing, plasticizer, lubricant, stabilizing agent and colouring agent, antistatic agent, etc., to become a good performance of plastic.
