Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a manufacturing process of a super wear-resistant belt, and the wear resistance of the manufactured belt is greatly improved.
The above object of the present invention is achieved by the following technical solutions:
a manufacturing process of an ultra-wear-resistant belt comprises the following process steps:
s1: the raw materials are put into an extruder in proportion for mixing, and after mixing is finished, the raw materials are extruded to obtain a mixed rubber material, wherein the raw materials comprise the following components in parts by weight:
s2: introducing the mixed rubber material into a calender for calendering to obtain a formed belt;
s3: and (5) coiling and packaging the formed belt to obtain a finished belt product.
By adopting the technical scheme, the super wear-resistant belt is mixed according to the raw material proportion, then the mixture is subjected to mixing extrusion to obtain a mixed material, all components in the mixed material are uniformly mixed by an extruder, then the mixed material is introduced into a calender for calendering and molding, the belt is obtained after molding, and then the belt is rolled and packaged. The production process of the super wear-resistant belt is simple and rapid, the working procedures are few, and the efficiency is high.
The raw materials of the super wear-resistant belt comprise butadiene rubber, natural rubber, styrene-butadiene rubber and wear-resistant resin which are used as main matrix resin of the super wear-resistant belt, so that the wear resistance of the super wear-resistant belt is enhanced. The addition of the wear-resistant filler and the filler reinforces the belt and reduces the volume cost. The stearic acid can soften and plasticize the matrix resin, fully disperse the filler and the wear-resistant filler, and promote the vulcanization of the rubber. The anti-aging agent is mainly used for prolonging the practical service life of the belt, reaches the surface of the belt through the migration effect and reacts with substances such as ozone and the like which cause aging, thereby achieving the purpose of prolonging the service life. The accelerator and the sulfur enable the rubber to be vulcanized, the reaction between the sulfur and the rubber is slow, the vulcanization is activated after the accelerator is added, the vulcanization time is shortened, and the efficiency is improved. By adding short fibers, the rubber is reinforced, and the rigidity of the belt in the length direction is enhanced by controlling the orientation of the fibers.
The present invention in a preferred example may be further configured to: the wear-resistant resin comprises the following components in percentage by weight:
20-50% of polyvinylidene fluoride;
15-40% of polyether-ether-ketone
10-40% of ultra-high molecular weight polyethylene.
By adopting the technical scheme, the polyvinylidene fluoride is a polymer of vinylidene fluoride, has the characteristics of both fluororesin and general resin, and has the characteristics of good chemical corrosion resistance, oxidation resistance and high strength; the polyether-ether-ketone is a special high polymer material, has better corrosion resistance and high temperature resistance, and has fatigue resistance under alternating stress which is comparable with that of an alloy material; the ultra-high molecular weight polyethylene is a thermoplastic engineering material with a linear structure, has very high strength and super wear resistance. Therefore, when the wear-resistant resin obtained by mixing polyvinylidene fluoride, polyether-ether-ketone and ultra-high molecular weight polyethylene is combined with other matrix resins in the raw materials, the wear-resistant performance of the belt is greatly enhanced, and the weather resistance and the corrosion resistance of the belt to the environment are enhanced. The present invention in a preferred example may be further configured to: according to the weight percentage, 2-3% of an auxiliary agent is also added into the wear-resistant resin, and the auxiliary agent comprises the following components in percentage by weight:
30-60% of sucrose ester;
20-30% of fluorocarbon surfactant;
20-40% of pentaerythritol ester.
By adopting the technical scheme, the sucrose ester, the fluorocarbon surfactant and the pentaerythritol ester are taken as the surfactants, and have the effect of promoting dispersion of all components in the wear-resistant resin, so that when all components in the wear-resistant resin are mixed with other matrix resins in the raw materials, the components are mixed more uniformly, all parts of the belt have uniform and stable performance, and the wear-resistant strength is excellent. The sucrose ester and the pentaerythritol ester contain a large amount of hydroxyl, and the oxygen in fluorine in polyvinylidene fluoride in the wear-resistant resin and the oxygen in carbonyl in polyether ether ketone in the wear-resistant resin are easy to form hydrogen bonds with hydroxyl hydrogen in the sucrose ester and the pentaerythritol ester, and the hydrogen bonds are less formed when the raw materials are mixed, so that the components in the auxiliary agent play a main role of a surfactant to disperse materials, and when extrusion, calendering and shaping are carried out, the hydrogen bonds are more formed, so that the auxiliary agent is used for connecting the components of the wear-resistant resin, a similar net structure is formed in the belt after calendering, the strength of the belt is improved, and the wear resistance of the wear-resistant resin to the belt is enhanced. The fluorocarbon surfactant has good compatibility, and can make sucrose ester and pentaerythritol ester well compatible. The present invention in a preferred example may be further configured to: the wear-resistant filler comprises the following components in percentage by weight:
50-60% of porous ceramic microspheres;
40-50% of nano magnesium oxide.
By adopting the technical scheme, the porous ceramic microspheres and the nano magnesium oxide have higher strength, wherein the size of the porous ceramic microspheres is equivalent to the fineness of common coating, the porous ceramic microspheres can be dispersed in a resin matrix, and the dispersed porous ceramic microspheres can improve the strength and the wear resistance of the belt. On one hand, the nano magnesium oxide can improve the mechanical strength of the belt and the wear resistance of the belt, and meanwhile, the flame retardant property of the belt can be improved by adding a large amount of nano magnesium oxide, so that the belt can be prevented from being burnt to be broken, and the safety is improved.
The present invention in a preferred example may be further configured to: the anti-aging agent comprises the following components in percentage by weight:
20-40% of N-phenyl-2-naphthylamine;
20-30% of N-phenyl-N' -isopropyl-p-phenylenediamine;
30-50% of N- (1, 3-dimethyl) butyl-N' -phenyl p-phenylenediamine;
by adopting the technical scheme, the N-phenyl-2-naphthylamine, the N-phenyl-N '-isopropyl-p-phenylenediamine and the N- (1, 3-dimethyl) butyl-N' -phenyl-p-phenylenediamine can play an anti-aging role in rubber components in the belt, and can migrate to the surface of the belt, so that substances which can generate oxidation action with the belt on the surface of the belt are reacted, and the service life of the belt is prolonged. The N-phenyl-N '-isopropyl-p-phenylenediamine and the N- (1, 3-dimethyl) butyl-N' -phenyl-p-phenylenediamine belong to p-phenylenediamine antioxidants, and can be complexed with stearic acid in raw materials to form a part of p-phenylenediamine antioxidants, and the stearic acid is used as a slow release agent, so that the antioxidants can be released and migrated to the surface to be supplemented after the antioxidants on the surface of the belt react, and the service life of the antioxidants is prolonged.
The belt generates heat due to friction in the using process, the more the generated heat is, the more the antioxidant complexed by stearic acid is released, the higher the concentration of the antioxidant on the surface of the belt is, so that the anti-aging capability of the belt is enhanced under the condition of higher temperature, and the service life of the belt is prolonged. And the nano magnesium oxide and the porous ceramic microspheres in the wear-resistant filler have good heat conductivity, so that heat generated in the moving process of the belt can be quickly transferred, the antioxidant complexed by stearic acid in the belt is quickly released in response, and the aging resistance of the belt is improved.
The present invention in a preferred example may be further configured to: the filler comprises the following components in percentage by weight:
70-80% of carbon black;
10-20% of white carbon black;
5-10% of a coupling agent.
By adopting the technical scheme, the filler is added to modify the carbon black and the white carbon black into the dual-phase filler for the belt, and the white carbon black is dispersed in the carbon black phase, so that the interaction between the filler and the filler is reduced, the action between the filler and the rubber is improved, and the wear resistance of the matrix resin is improved. The addition of the coupling agent causes a small amount of gel to be generated during the mixing of the raw materials in the extruder, and the gel helps to increase the viscosity of the matrix resin, thereby causing a tighter bond between the matrix resin and the filler.
The present invention in a preferred example may be further configured to: the temperature of a feeding section in the extruder is controlled to be 55-65 ℃, the temperature of a screw of the extruder is controlled to be 80-90 ℃, and the temperature of a machine head of the extruder is controlled to be 90-100 ℃.
