Abstract
The present invention relates to a kind of cold-resistant waterproof material manufacture method, wherein, cold-resistant waterproof material comprises polythene material and middle colour carbon black, and the ratio of weight and number of described polythene material and described middle colour carbon black is 100:1; Manufacture method comprises the following steps: S1, polythene material and middle colour carbon black are evenly mixed, the ratio of weight and number of polythene material and middle colour carbon black is 100:1; S2, mixed polythene material and middle colour carbon black are imported in the screw rod of extruder, extrusion molding, the temperature of extruder is made as 160 DEG C; Described polythene material and described middle colour carbon black are coated on by extruder on the PVC layer of cable, and the specific area of described middle colour carbon black is 120-145m2/ g. The cold resistance of the cold-resistant waterproof material of the present invention is good, can bear the low temperature of-60 DEG C, simultaneously good waterproof performance.
Description
Technical field
The present invention relates to a kind of cold-resistant waterproof material manufacture method.
Background technology
At severe cold frost region, many materials are impaired because bearing low temperature, can not meet normal useNeed, for example cable, often because cold tolerance does not reach instructions for use, breaks and opens circuit, and causes signal transmission disorderlyDisorderly, make equipment produce misoperation, cause casualties and property badly damaged.
Summary of the invention
The technical problem to be solved in the present invention is, for the poor defect of existing material cold resistance, provides oneKind cold resistance well has the cold-resistant waterproof material manufacture method of water proofing property concurrently simultaneously.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of cold-resistant waterproof material manufacture method, comprises the following steps: S1, by polythene material and middle pigmentCarbon black evenly mixes, and the ratio of weight and number of polythene material and middle colour carbon black is 100::1; S2, will mixPolythene material after closing and middle colour carbon black import in the screw rod of extruder, extrusion molding, the temperature of extruderDegree is made as 160 DEG C; Described polythene material and described middle colour carbon black are coated on cable by extruderOn PVC layer, the specific area of described middle colour carbon black is 120-145m2/g。
Implement cold-resistant waterproof material manufacture method of the present invention, there is following beneficial effect: polythene material toolThere are good water resistance and low temperature tolerance ability, can bear the low temperature of-60 DEG C. Carbon black strong coloring force, viscosityLow, good fluidity, good with the amalgamation of polyethylene material, when polythene material and carbon black are coated by extruderOn PVC layer on cable time, very close to each other between cold-resistant waterproof material and PVC layer, form goodOvercoat, the cable that is coated with cold-resistant waterproof material has good cold resistance and water proofing property. Meanwhile, carbon blackAlso have good UV resistant function, improved the ageing-resistant performance of product.
Detailed description of the invention
Understand existing detailed description in detail originally for technical characterictic of the present invention, object and effect being had more clearlyThe detailed description of the invention of invention.
The present invention's waterproof material that resists cold, comprises polythene material and carbon black, polyethylene (PE, Polyethylene)The ratio of weight and number of material and carbon black is between 90:1 to 110:1. Polythene material has good waterproofPerformance and low temperature tolerance ability, can bear the low temperature of-60 DEG C. Carbon black strong coloring force, viscosity are low, good fluidity,Good with the amalgamation of polyethylene material, when polythene material and carbon black are coated on the PVC on cable by extruderOn layer time, very close to each other between cold-resistant waterproof material and PVC layer, form good overcoat, be coated withThe cable of cold-resistant waterproof material has good cold resistance and water proofing property. Meanwhile, carbon black also has good resistance to purpleOutside line function, has improved the ageing-resistant performance of product.
Further, the ratio of weight and number of polythene material and described carbon black is 100:1, carbon black can with poly-secondAlkene material fully merges, effective. Should be understood that, the ratio of weight and number in the present embodiment is just a kind ofPreferred embodiment.
Further, the carbon black in the present embodiment is middle colour carbon black, and the specific area of carbon black is 120-145m2/ g. This is a kind of preferred carbon black, can be better and polythene material fusion.
The present invention also provides a kind of cold-resistant waterproof material manufacture method, comprises the following steps:
S1, polythene material and carbon black are evenly mixed, the ratio of weight and number of polythene material and carbon black isBetween 90:1 and 110:1, preferred ratio of weight and number is 100:1;
S2, mixed polythene material and carbon black are imported in the screw rod of extruder, extrusion molding, extrudesThe temperature of machine is made as between 150 DEG C to 170 DEG C, is preferably set to 160 DEG C. Cold-resistant waterproof material after extrudingMaterial can directly be coated on the oversheath of cable, forms other layer protective layer. The oversheath of general cableFor PVC (PolyVinylChloride, polyvinyl chloride) layer, outside is coated after new protective layer, waterproofPerformance is improved, and cold resistance is good simultaneously.
Above embodiments of the invention are described, but the present invention is not limited to above-mentioned concrete realityExecute mode, above-mentioned detailed description of the invention is only schematically, instead of restrictive, this area generalLogical technical staff under enlightenment of the present invention, the scope that is not departing from aim of the present invention and claim and protectIn situation, also can make a lot of forms, within these all belong to protection of the present invention.
