Description
Technical field
The present invention relates to suitable in bank protection class twisted pair steel wire field, particularly to a kind of twisted pair steel wire semihard ash material PVC plastic that resists cold.
Background technology
For a long time, because the construction landslide in formed hillside fields, soil erosion bring great hidden danger to our personal safety as well as the property safety.In order to solve this problem, be generally adopted the method covering lid layer twisted pair steel wire in slope at present and it reinforced, through 3～5 years, until slope grow various vegetation have self protect soil function time, the bank protection effect of twisted pair steel wire completes.In order to make twisted pair steel wire reach the service life of regulation, it is armor coated that we are everlasting on steel wire, it is prevented that the oxidized degraded of steel wire.
It is known that PVC plastic is with its cheap price, good ageing resistance and mechanical performance etc., the fields such as all kinds of protective layer, wire cable insulating material it are successfully applied to.Owing to bank protection class twisted pair steel wire uses the particularity of environment; PVC plastic is when as twisted pair steel wire protective layer, and As time goes on long-term easily aging under sun exposure, mechanical strength is unstable with ambient temperature; especially, easily harden and cracking etc. at low ambient temperatures.Based on said one or multiple shortcoming, cause that domestic PVC plastic slowly fails to be applied in twisted pair steel wire field for a long time.
Chinese patent CN201210396064 " the PVC sizing material that tolerance to cold improves " discloses the use of the cold resistant plasticizer of high level in order to improve the cold-resistant impact fracture rate of material, but the disclosure patent does not illustrate cold resistant plasticizer type used and its implementation result describes fuzzy；Chinese patent CN201410470912 " PVC cable jacket of a kind of resistance to cold and summer-heat " discloses the formula of a kind of PVC cable jacket, the stability when lifting of its performance is mainly reflected in high temperature resistant, and this PVC plastic and is mainly used in cable insulating material；Chinese patent CN102352077A " a kind of stone wood plastic composite " discloses a kind of environment-friendly anti-aging PVC plastic, PVC and stabilizer, calcium carbonate, titanium dioxide, ACR is adopted to combine, but its photooxidation resistant and photoaging effect are bad, cold-resistant bad mechanical strength etc.；Chinese patent CN201310295810 " a kind of resistance to oxidation PVC " adopts PVC and bisphenol-A, triphenyl phosphite, epoxy chloroparaffin, plasticizer, heat stabilizer, UV absorbent, antioxidant combines, but this patent does not consider mechanical strength when it is cold-resistant owing to its technical field limits.
Although the PVC plastic synthesizing formula that current domestic patent relates to is a lot, but also fail to find a kind of bank protection class twisted pair steel wire that can fully meet to use the PVC plastic of environmental requirement.
Summary of the invention
For solving above-mentioned prior art Problems existing, it is an object of the invention to provide a kind of PVC plastic that disclosure satisfy that twisted pair steel wire Special use environment.
For reaching above-mentioned purpose, the technical scheme is that
A kind of twisted pair steel wire semihard ash material PVC plastic that resists cold, the composition of described semihard ash material PVC plastic and proportioning are (mass parts meter):

The above-mentioned twisted pair steel wire semihard ash material PVC plastic that resists cold, described plasticizer is mixed by a certain percentage by SA dioctyl ester, dimethyl phthalate and epoxy soybean oil.
The above-mentioned twisted pair steel wire semihard ash material PVC plastic that resists cold, described complex stabilizer is lanolin fatty acid calcium-zinc composite stabilizing agent.
The above-mentioned twisted pair steel wire semihard ash material PVC plastic that resists cold, described filler is calcium carbonate.
The above-mentioned twisted pair steel wire semihard ash material PVC plastic that resists cold, described lubricant is ACR401.
The above-mentioned twisted pair steel wire semihard ash material PVC plastic that resists cold, described antioxidant is diphenol propane (bisphenol-A).
The above-mentioned twisted pair steel wire semihard ash material PVC plastic that resists cold, described ultraviolet-resistant absorbent is Octabenzone (UV531).
Described plasticizer mass parts in the total component of formula is that SA dioctyl ester is 10～20 mass parts, dimethyl phthalate 20～30 mass parts, epoxy soybean oil 5～15 mass parts.
Relative to prior art, the invention have the benefit that
In this formula, patent of the present invention adds the SA dioctyl ester that content is higher in PVC plasticizer, in order to improve the resistance to low temperature of this material, makes this material still have the mechanical strength of excellence under cryogenic.Simultaneously patent of the present invention uses diphenol propane (bisphenol-A) as antioxidant and Octabenzone (UV531) as ultraviolet-resistant absorbent in PVC synthesizing formula, makes this material possess excellent photooxidation resistant and photoaging ability.Appropriate amount of components ensure that the heat stability of this material, particularly mechanical strength under cryogenic.Product prepared by the current present invention has been successfully applied to twisted pair steel wire field, and is mark Fei Er (Changsha)NovelZhi Dang Science and Technology Development Co., Ltd. stably supplies.Product simultaneously involved in the present invention can also apply to cold-resistant condition is required higher electric wire PVC plastic field, and can play the effect more excellent than other properties of product similar.The successful Application of this material breaks external monopolization, has filled up domestic blank, and especially, the successful exploitation of this material makes its price reduction to imported material half, brings good social benefit and economic benefit.
