Abstract
The invention discloses a formula of a low-cost environment-friendly flame-retardant 105-DEG C PVC cable material, belonging to the field of formulas of cable materials. The low-cost environment-friendly flame-retardant 105-DEG C PVC cable material comprises the following components in parts by weight: 100 parts of PVC resin, 30-50 parts of TOTM, 3-8 parts of epoxidized soybean oil, 1-3 parts of 70 chlorinated paraffin, 2-5 parts of antimony oxide, 0.3-0.8 part of an antioxidant, 60-80 parts of activated calcium carbonate, 5-10 parts of a calcium-zinc compound stabilizer, 10-15 parts of a flexible strength agent, 1-3 parts of an internal/external lubricant and 5-20 parts of DOS. The low-cost environment-friendly flame-retardant 105-DEG C PVC cable material has the advantages of high elongation, tensile strength and tearing strength, good toughness and elasticity and low cost.
Description
Technical field
The invention belongs to a kind of cable material formula, specifically, particularly relate to the fire-retardant 105 DEG C of PVC cable material formulas of a kind of low-cost environmental-protecting.
Background technology
Tradition 105 DEG C of basic materials softening agent of PVC level CABLE MATERIALS select TOTM usually, general 50 parts of conventional amount (100 parts of resins), but its kneading property is good not as good as DOP, mixed processes mixing time long (> 25 minutes), system viscosity is large, good cooling is not had to be easy to the caking that heats up, or stir and do not become dry powder to cause plasticizing bad, simultaneously due to not blanking restriction output, the use of serious restriction common singe screw tablets press processing units, especially require that low temperature flexibility uses in the formula of DOS well simultaneously, mixing becomes more difficult, energy consumption is very large, simultaneously in air-cooled pelletizing machine, temperature height very easily clay, the low plasticizing of temperature is poor.And formulation cost is very high, general enterprises is difficult to bear, and when manufacture 105 DEG C of high-temperature fine wires, especially has the technique of dipping in insullac and drying, and is easy to electric wire embrittlement occurs, and exposes copper wire and causes electronic unit to be scrapped.Its basic reason is that CABLE MATERIALS tear-resistant effect is poor, and toughness is inadequate, and 70 chlorinated paraffin decomposition, product hardness is large.Overcome the above problems, conventional thinking strengthens plasticising dosage, use cold resistant plasticizer as DOS, or use the anti-impact agent such as ACR, EVA, CPE, but product strength degradation, flame retardant effect worsens, cost significantly increases, especially cause mixing difficulty, easily lump without material in cooling situation, cause burn-down of electric motor.
Summary of the invention
The object of the invention is to provide that a kind of elongation and tensile strength and tear strength are high, the fire-retardant 105 DEG C of PVC cable material formulas of a kind of low-cost environmental-protecting of snappiness and good springiness, to overcome above-mentioned defect of the prior art.
The present invention realizes by the following technical solutions:
The fire-retardant 105 DEG C of PVC cable material formulas of a kind of low-cost environmental-protecting, comprise following weight ratio formula: polyvinyl chloride resin 100 parts, TOTM30-50 part, epoxy soybean oil 3-8 part, 70 clorafin 1-3 parts, weisspiessglanz 2-5 part, oxidation inhibitor 0.3-0.8 part, activated Calcium carbonate 60-80 part, calcium-zinc composite stabilizing agent 5-10 part, soft strong agent 10-15 part, inside and outside lubrication prescription 1-3 part, DOS5-20 part.
Described inside and outside lubrication prescription is PE wax and stearic acid.
Preferably, following weight ratio formula is comprised: polyvinyl chloride resin 100 parts, TOTM45 part, epoxy soybean oil 5 parts, 70 clorafin 1 part, weisspiessglanz 2-5 part, 0.5 part, oxidation inhibitor, activated Calcium carbonate 75 parts, calcium-zinc composite stabilizing agent 6 parts, soft strong agent 10 parts, inside and outside lubrication prescription 2 parts, DOS10 part.
Compared with prior art, the invention has the beneficial effects as follows:
1, environment-protecting asepsis of the present invention, significantly reduces production cost, significantly improves the elongation of goods and tensile strength and tear strength, significantly strengthens goods snappiness and elasticity, effectively improve goods bending albefaction problem; Significantly improve loading level, reduce softening agent usage quantity, improve cold-resistant, anti-aging, the oil resistant of goods, insulation, water resistance;
2, extrusion capacity of the present invention significantly improves, remarkable reduction melt viscosity, improve PVC product surface-brightening smooth finish, make goods feel good, pigment stability is increased, color is more lastingly bright-coloured, in elastic material, significantly improve snappiness and the elasticity of goods, and liquid towards plasticizing oil there is strong affinity, plasticizing oil is fixed in goods and does not move, anti-fuel-displaced and goods glue hand, and Article Stiffness Determination is stablized.
