Abstract
The invention relates to an organic high polymer composite material, more specifically to wear-resistant filling plastic, comprising the following components by weight ratio: 45-72.5% of nylon, 10-25.5% of phenolic aldehyde, 4-25% of halogen free nitrogen and phosphorus fire retardant, 0.5-8.5% of graphite, 0.5-3.9% of molybdenum disulfide, 0.5-4.7% of dispersing agent, 0.1-1.8% of antioxidant and 0.3-3.2% of active carbon. The wear-resistant filling plastic provided by the invention can improve the anti-rubbing and anti-abrasion performances of plastic by adding graphite and molybdenum disulfide as filler and reduce the cost of plastic by adding the filler.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of wear-resistant filled plastics.
Background technology
The physicochemical property different according to various plastics; Can be divided into two types of thermosetting resin and thermoplastic plastics to plastics; Thermoplastics (Thermo plastics): refer to melt after the heating, can flow to the mold cools down aftershaping, the plastics that can melt again behind the reheat; Can use heating and cooling, make its generations reversible change (liquid state ← → solid-state), be so-called physical change.Its successive use temperature of general thermoplastics is below 100 ℃, Vilaterm, SE, gathers nylon 6, PS and is called four big general-purpose plastics.Thermosetting resin be meant be heated or other conditions under can solidify or have insoluble (melting) characteristic plastics, like phenoplast, epoxy plastics etc.Thermosetting resin divides two types of formaldehyde crosslinking type and other cross-linking types again.Formation cannot not have moltenly insoluble cured article behind the thermo forming, and its molecular resin is cross-linked into reticulated structure by linear structure.Add heat-flash again and then can decompose destruction.Typical thermosetting resin has materials such as phenolic aldehyde, epoxy, amino, unsaturated polyester, furans, poly(silicon aether), also has newer polyphenyl dioctyl phthalate two nylon 6 ester plastics etc.They have the thermotolerance height, the advantage such as not yielding of being heated.
Nylon 6 is to use one of several kinds of maximum engineering plastics at present; His amide group has polarity; In his structure, has well-set hydrogen bond; Make that the fusing point of nylon 6 is higher, have good physical and mechanical property and wear resistance and self lubricity, these comprehensive characteristics are that other plastics are not available.But there is the imperfect shortcoming of flame retardant resistance in pure nylon 6, thereby has limited the application of nylon 6, and then has dwindled downstream industry design engineer's selection leeway again.Therefore, launched nylon 6 is carried out the research of composite flame-proof modification.
Mainly use nylon 6 to come with some shortcomings for the main plastics of making composition, not wear-resisting, the plastics that every usefulness is of a specified duration, aging Chengdu is very fast, and all there are some frictions in frosting, and is not attractive in appearance, and also has some quality crisp partially.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide a kind of and keeping good wear-resistant filled plastics at comprehensive mechanical performance.
Technical scheme provided by the invention is following: a kind of wear-resistant filled plastics of the present invention, by following composition by weight forming nylon 6:45-72.5%; Phenolic aldehyde: 10-25.5%; Halogen nitrogen phosphorus flame retardant: 4-25%; Graphite: 0.5-8.5%; Molybdenumdisulphide: 0.5-3.9%; Dispersion agent: 0.5-4.7%; Inhibitor: 0.1-1.8%; Gac: 0.3-3.2%.
Wear-resistant filled plastics-production flow process of the present invention is: earlier nylon 6 is carried out mechanical stirring or vibration, add dispersion agent simultaneously, make monomer be dispersed into drop; The polymerization process that suspends in water and carry out, operations such as the polymkeric substance that obtains separates, washing, drying promptly get the synthetic resins of nylon 6; In synthetic resins, add a certain amount of phenolic aldehyde, Halogen nitrogen phosphorus flame retardant, inhibitor, gac again; In order to make the plastics that make have certain wear resisting property, also should add graphite, molybdenumdisulphide, these two kinds of additives all possess wear resisting property; And two kinds of reagent can serve as stopping composition simultaneously to be used; Further reduced the cost of manufacture of plastics, treat the reaction of these solvent thorough mixing after, obtain the salts solution of nylon 6; Carry out saturated processing and should be 80-95T heat-wind circulate drying 6 hours with the saturated solution of nylon 6; Place bolt special at last, penetrate in the injection moulding machine of chewing with independent temperature control, and the temperature in the injection moulding machine is set to 160 degrees centigrade, the reaction times is can make wear-resistant filled plastics in 5 hours.
The advantage of a kind of wear-resistant filled plastics of the present invention: add as stopping composition through graphite and molybdenumdisulphide, can improve wear-resisting wiping, the abrasion resistance properties of plastics, also add stopping composition simultaneously and can also reduce the plastics cost; Production procurement is convenient; Employing halogen-free environmental technology reduces the pollution to environment, all adopts homemade supplementary material and additive and production unit; Production cost and material cost reduce greatly, effectively raise the comprehensive competitive power of product like this.
Embodiment
Below be the most preferred embodiment of wear-resistant filled plastic raw materials of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of wear-resistant filled plastics are provided, by following composition by weight forming nylon 6:66.8%; Phenolic aldehyde: 12.8%; Halogen nitrogen phosphorus flame retardant: 5.8%; Graphite: 6.5%; Molybdenumdisulphide: 2.4%; Dispersion agent: 2.1%; Inhibitor: 0.9%; Gac: 2.7%.
Earlier nylon 6 is carried out mechanical stirring or vibration; Add dispersion agent simultaneously, make monomer be dispersed into drop, the polymerization process that suspends in water and carry out; Operations such as the polymkeric substance that obtains separates, washing, drying; Promptly get the synthetic resins of nylon 6, in synthetic resins, add a certain amount of phenolic aldehyde, Halogen nitrogen phosphorus flame retardant, graphite, molybdenumdisulphide, inhibitor, gac again, obtain the salts solution of nylon 6; Carry out saturated processing and should be 80-95T heat-wind circulate drying 6 hours with the saturated solution of nylon 6; Place bolt special at last, penetrate in the injection moulding machine of chewing with independent temperature control, and the temperature in the injection moulding machine is set to 160 degrees centigrade, the reaction times is can make wear-resistant filled plastics in 5 hours.
The above; Be merely embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
