What chemicals should be used in plastic products?

Answer:

Additives mainly in the following categories:OneAntioxidantsAntioxidantUnsaturated double bonds in plastics are absorbed by oxygen atoms, heat and lightCaused by breaking, resulting in free radicals, which cause a chain reaction, so that the molecular chain scission or formation of chain cross-linking,Resulting in lower or weaker strength of plastic products. The function of antioxidants is to delay the oxidation of plasticsBreak down and prolong the life of plastic products. The antioxidants used in the plastics industry can be divided into functions: (One)Inhibitors of oxidative chain reactions, such as alkylphenolAlkylPhenolButyl tolueneButylatedHydroxytolueneAbbreviationBHT) aromatic aminesAromaticAmines) phenyl - -B-Resistant amine(Phenyl-B-Naphthylamine), were of Kun (AlkylQuinoneAlkenyl bisphenol A(AlkyleneBisphenolAlkyl phenol sulfideAlkylPhenolthioetherSalicylic acidBenzene fingerPhenylSalicylateAnd so on) etc.. (

Several commonly used plastic additivesPlastic additives can be divided into seven categories according to their specific functions: additives for improving processability, such as thermal stabilityA constant agent, lubricant, etc. Additives for improving mechanical properties, such as plasticizers, toughening agents, etc.. The changeAdditives for good surface properties, such as antistatic agents, coupling agents, etc.. Additives to improve optical properties, such asColorant, etc.. Additives to improve aging properties, such as antioxidants, light stabilizers, etc.. The reduction of plasticAn additive such as an extender, a filler, etc.. The specific effect of giving other additives such as foaming agent,Flame retardant and anti mildew agent etc..Additives are meant to be dispersed in the plastic molecular structure without serious impactA chemical structure of plastics that improves its properties or reduces its cost. Addition of additives, energyThe plastic can improve the processing, physical and chemical functions of the base material and increase the physics and chemistry of the base materialCharacteristic。
