Abstract
The invention discloses a polyvinylchloride low temperature resistance and anti-aging salt film to prevent rainfall from diluting bittern, which comprises the following parts: (A) polyvinylchloride resins 100 parts; (B) 10-40PHR phthalandione dioctyl; (C) 10-40PHR terephthalic dioctyl; (D) 2-12 PHR adipinic dioctyl; (E) 2-5 PHR thermally-stabilized agent; (F) 1-4 PHR carbon black; (G) 0.1-40 PHR 2- hydroxyl-4- n-octyl oxide benzophenone (or 2- hydroxyl-4-methyl benzophenone); (H) 0.1-0.8 PHR 4, 4- isopropylidene bisphenol. The invention can be used in low temperature condition, which improves the salt film lifetime.
Description
One, technical field:
The present invention relates to a kind of polyvinyl chloride film of protecting salt pond bittern to use, particularly a kind of overcast and rainy covering prevents that on the salt pool surface rainwater from watering down the low temperature resistant polyvinyl chloride of bittern, salt film for anti-aging.
Two, background technology:
At present, the polyvinyl chloride salt film of known technology mainly is to be added auxiliary agents such as softening agent, stablizer, carbon black by polyvinyl chloride (PVC) RESINS, through the common polyvinyl chloride film that mixes, plastifies, makes after the processes such as calendering.Wherein, softening agent is based on dioctyl phthalate (DOP), and Octyl adipate (also available dioctyl sebacate replaces) is auxilliary as low temperature resistant softening agent, the plasticity of reinforced polyvinyl chloride resin.This be that the low temperature flexibility of film is very restricted under the Plasticising system of primary plasticizer with the dioctyl phthalate (DOP), film will hardening when envrionment temperature is lower than 5 ℃, the user just dare not folding and unfolding, in order to avoid film breaks.
Aspect the opposing ultraviolet ray ageing, the traditional salt film producer is existing mistaken ideas to the approach that ultraviolet ray destroys the salt film aspect the understanding: think that the salt film only in overcast and rainy use, can not be subjected to the direct projection of sunlight, so be subjected to the chance of ultraviolet ray infringement just few.Actually this is not so, though when cloudy day cloud layer stopped ultraviolet direct projection,, cloud layer but can strengthen ultraviolet diffuse-reflectance, so the salt film still can be subjected to ultraviolet destruction when cloudy.The ordinary salt film mainly with carbon black as ultraviolet screening agent, ultraviolet ray is intercepted, prevent its destruction to the polyvinyl chloride molecular chain, its effect is not fine, so have a greatly reduced quality the work-ing life of ordinary salt film.
Three, summary of the invention:
Purpose of the present invention is exactly the above-mentioned defective that exists at prior art, provide a kind of and aspect low temperature resistant, anti-aging, obtain abundant improved polyvinyl chloride salt film, thereby solve salt membrane product out of use situation under the lesser temps state, and effectively improve low temperature resistant polyvinyl chloride, the salt film for anti-aging in the work-ing life of salt film.
Its technical scheme is: comprise that following component is formulated: (A) 100 parts of weights of polyvinyl chloride (PVC) RESINS; (B) dioctyl phthalate (DOP) 10-40PHR; (C) dioctyl terephthalate 10-40PHR; (D) Octyl adipate 2-12PHR; (E) thermo-stabilizer 2-5PHR; (F) carbon black 1-4PHR; (G) Octabenzone (or 2-hydroxy-4-methyl benzophenone) 0.1-0.6PHR; (H) 4,4-isopropylidene bis-phenol 0.1-0.8PHR.
Described thermo-stabilizer can be selected liquid stabilisers and the compound use of metallic soap class stablizer for use, and at least one section of metallic soap class stablizer selects barium stearate or lead stearate.
In plasticiser system, substitute the part dioctyl phthalate (DOP) with dioctyl terephthalate.In the photostabilizer system, add Octabenzone or 2-hydroxy-4-methyl benzophenone.
In the above-mentioned prescription: (1) substitutes dioctyl phthalate (DOP) with the part dioctyl terephthalate, because the special linear chain structure of dioctyl terephthalate molecule, its stable performance, low temperature resistant effect is better than dioctyl phthalate (DOP); The low temperature resistant softening agent Octyl adipate in prescription Central Plains continues to use.The thin film low temperature snappiness is by dioctyl terephthalate and the common realization of Octyl adipate; (2) adopt Octabenzone (or 2-hydroxy-4-methyl benzophenone) as UV light absorber in the photostabilizer system, under the prerequisite that carbon black effectively shields ultraviolet ray, strengthened the ultraviolet absorption of incident, effectively prevented the photooxidation resistance of film.
The invention has the beneficial effects as follows: low temperature resistant, anti-aging aspect obtains abundant improved polyvinyl chloride salt film, thereby solves salt membrane product out of use situation under the lesser temps state, and the work-ing life of effectively improving the salt film; The one, solved when winter temperature is lower than 5 ℃ can not folding and unfolding salt film problem; The 2nd, can make to prolong 2-3 in work-ing life of salt film.
Four, embodiment:
Embodiment 1: its prescription comprises that following component is formulated: (A) 100 parts of weights of polyvinyl chloride (PVC) RESINS; (B) dioctyl phthalate (DOP) 10PHR (resin by 100 parts of weights is the parts by weight of the other materials of benchmark, down together); (C) dioctyl terephthalate 10PHR; (D) Octyl adipate 2PHR; (E) thermo-stabilizer 2PHR; (F) carbon black 1PHR; (G) Octabenzone (or 2-hydroxy-4-methyl benzophenone) 0.1PHR; (H) 4,4-isopropylidene bis-phenol 0.1PHR.Wherein, thermo-stabilizer can be selected liquid stabilisers and the compound use of metallic soap class stablizer for use, at least a barium stearate or the lead stearate of selecting of metallic soap class stablizer.
In addition, in plasticiser system, substitute the part dioctyl phthalate (DOP) with dioctyl terephthalate; In the photostabilizer system, add Octabenzone or 2-hydroxy-4-methyl benzophenone.
Embodiment 2: 100 parts of weights of (A) polyvinyl chloride (PVC) RESINS in the said components; (B) dioctyl phthalate (DOP) 40PHR; (C) dioctyl terephthalate 40PHR; (D) Octyl adipate 12PHR; (E) thermo-stabilizer 5PHR; (F) carbon black 4PHR; (G) Octabenzone (or 2-hydroxy-4-methyl benzophenone) 0.6PHR; (H) 4,4-isopropylidene bis-phenol 0.8PHR.
Embodiment 3: in the said components with reference to following table.
After 1 each component is weighed in the table one, stirred 5 minutes with homogenizer, under 165 ℃, plasticate then with Banbury mixer, carry out mixing in the open type plastic purificating set kind again, after forcing machine filters, roll into film by four-roll calender, the film after the moulding is shaped into desired product through drawing-off, expanding postcooling.The product low-temperature extension can reach 35%, and can reach more than 7 years work-ing life.
After weighing by each component of 2 in the table one, under 170 ℃ temperature, also can make the utility model product by the processing method of the foregoing description.
