Abstract
The invention relates to polyvinyl chloride plastics. The polyvinyl chloride plastics comprise the following raw materials in parts by weight: 30 to 60 parts of polyvinyl chloride resin, 10 to 15 parts of a plasticizer, 5 to 15 parts of an antioxidant, 13 to 25 parts of a coloring agent, 3 to 10 parts of a flame retardant agent, 1 to 6 parts of stearate, 1 to 4 parts of triethanolamine and 0.1 to 0.5 part of sodium diethyldithiocarbamate. By adding the plasticizer, the combustibility of the soft polyvinyl chloride plastics can be reduced, the safety is guaranteed, and the soft polyvinyl chloride plastics have better flame-retardant property.
Description
Technical field
The present invention relates to a kind of igelite, belong to plastic cement field.
Background technology
Plastics are taking synthetic resins as major ingredient, and add other additive, and the high molecular synthetic material of plasticizing forming under certain temperature and pressure, after chemical reaction is synthetic, synthetic plastics be by many compared with little and simple in structure small molecules, combined by covalent linkage.Plastics of a great variety, if generally classify with the variation to heat, it can be divided into two large classes: after thermosetting resin heating, can make molecular configuration be combined into net pattern, once be combined into network polymer, can not soften even if reheat also; Can fusing after thermoplastics heating, can flow to mold cools down aftershaping, the plastics that can melt again after reheating, can use heating and cooling, make it produce [reversible change] (liquid ← → solid-state), are so-called physical changes.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of good toughness, the igelite of good transmittance.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of igelite, comprises the raw material of following parts by weight: 30～60 parts of polyvinyl chloride (PVC) RESINS, 10～15 parts, softening agent, 5～15 parts, oxidation inhibitor, 13～25 parts of tinting materials, 3～10 parts of fire retardants, 1～6 part of stearate, 1～4 part of trolamine, 0.1～0.5 part of Thiocarb.
The invention has the beneficial effects as follows:
It is the combustibility in order to reduce soft PVC plastics that the present invention adds the object of softening agent, ensures its safety, in order to make soft PVC plastics there is better flame retardant resistance, and the preferred phthalic ester plasticizer of flame-retardant plasticizer or phosphoric acid.The object that adds oxidation inhibitor be for fear of PVC in processing use procedure, because being heated, ultraviolet effect is oxidized, and for antioxidant is combined with radical, forms stable compound, makes chain reaction termination, preferably selects dihydroxyphenyl propane as oxidation inhibitor.The present invention, in the time selecting dihydroxyphenyl propane as oxidation inhibitor, can add triphenyl phosphite and phosphorous acid benzene di-isooctyl as auxiliary antioxidant, and major-minor oxidation inhibitor is also with bringing into play synergy.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the optimum value of described igelite comprises the raw material of following parts by weight: 35 parts of polyvinyl chloride (PVC) RESINS, 11 parts, softening agent, 10 parts, oxidation inhibitor, 15 parts of tinting materials, 5 parts of fire retardants, 4 parts of stearate, 3 parts of trolamines, 0.4 part of Thiocarb.
Further, described softening agent is phthalic ester plasticizer and/or phosphate plasticizer.
Further, described oxidation inhibitor is dihydroxyphenyl propane, triphenyl phosphite or phosphorous acid benzene di-isooctyl.
Further, described tinting material comprise that phthalocyanine is red, any one or plural mixing in chrome yellow, cadmium yellow, titanium dioxide or carbon black.
Further, described fire retardant is any one in clorafin, antimonous oxide or phosphoric acid ester.
