Description
Technical field
The present invention relates to a kind of polymeric material field, be specifically related to a kind of PVC guardrail formula and preparation method thereof.
Background technology
Guardrail i.e. fence, refers to industrial " guard rail ", guardrail is mainly used in house, highway, shopping centre, public place etc.
To personal safety and the protection of installations and facilities and protection in occasion.
Traditional guardrail is generally made up of steel, such as rustless steel, round steel pipe, square steel tube or profiled sheet, but steel
Guardrail easily cave in, and color mostly is single Lycoperdon polymorphum Vitt, and moulding is dull, needs periodic maintenance, and difficulty of construction is big, the easy oxygen of steel plate simultaneously
Metaplasia is embroidered, and produces relatively costly, even if lighter impulsive force easily causes guardrail deformation；In addition steel produce and to consume many energy
Source, and production process easily produces pollution.The most now commonly used macromolecular material is as guardrail material, such as PVC and moulds
Material etc..
Although but plastic product has a heat conductivity advantage little, lower-cost, but the most aging becoming fragile, intensity is low；Cause
For this fence used as open air, it is clear that not having advantage, so PVC guardrail is widely used, prior art is to PVC
When guardrail produces, a kind of modified PVC injection molding plastic for fence fitting as disclosed in Chinese patent CN200810135358.X,
Raw material includes S～700PVC45-55, methyl stannum 1.7-1.9, stearic acid 0.18-0.22, paraffin wax 0.09-0.1, ACR1.6-2, titanium
White lead 2.3-2.7, calcium carbonate 4.5-5.5, CPE3.6-4.4, UV absorbent 0.23-0.27, antioxidant 0.23-0.27, increasing
White agent 3.8-4.1, ultramarine 5.5-6.6, although the PVC guardrail intensity being processed into is high, toughness foot, but owing to PVC(mass is 45
Between ~ 55 parts, and raw material total amount is only 70 ~ 80) ratio exceeded 65%, and this has also resulted in steeply rising of cost, PVC ratio
Example is less than 65%, is unsatisfactory for again toughness requirements；In addition processing technique generally uses a plasticizing forming so that the PVC after molding protects
Hurdle low in glossiness, basic no-reflection effect, it is unsatisfactory for consumer demand.
Summary of the invention
The invention is intended to provide a kind of PVC guardrail formula and preparation method, excessive to solve prior art PVC content, make
The problem playing the guardrail low in glossiness after the rising of cost and molding.
A kind of PVC guardrail formula in this programme, including major ingredient and adjuvant, described major ingredient is calculated as with parts by weight: calcium powder
40 ~ 60 parts, polyvinyl chloride resin 70 ~ 80 parts, described adjuvant with parts by weight be calculated as CPE5 ~ 6 part, stabilizer 3.5 ~ 4 parts, titanium dioxide 0 ~
3.5 parts, stearic acid 0.5 ~ 1 part, 0.5 ~ 1 part of PE wax, dioctyl ester 2 ~ 2.5 parts, ACR2 ~ 2.5 part, 0 ~ 0.15 part of brightening agent.
One of them embodiment: PVC guardrail formula, each constituent is calculated as with parts by weight: calcium powder 40 parts, polyvinyl chloride resin
70 parts, CPE5 part, stabilizer 3.5 parts, titanium dioxide 3.5 parts, stearic acid 0.5 part, 0.5 part of PE wax, dioctyl ester 2 parts, ACR2 part, increasing
White agent 0.15 part.
Another embodiment: PVC guardrail formula, each constituent is calculated as with parts by weight: calcium powder 50 parts, polyvinyl chloride resin 75
Part, CPE6 part, stabilizer 4 parts, stearic acid 0.7 part, 0.7 part of PE wax, dioctyl ester 2 parts, ACR2 part.
Another embodiment: PVC guardrail formula, each constituent is calculated as with parts by weight: calcium powder 60 parts, polyvinyl chloride resin 80
Part, CPE6 part, stabilizer 4 parts, titanium dioxide 3.5 parts, stearic acid 1 part, 1 part of PE wax, dioctyl ester 2.5 parts, ACR2.5 part, brightening agent
0.15 part.
Beneficial effects of the present invention: 1, use calcium powder, polyvinyl chloride resin, CPE, stabilizer, titanium dioxide, stearic acid, PE wax, two
Monooctyl ester, ACR and brightening agent are as raw material, and wherein titanium dioxide is mainly anti-ultraviolet effect, ACR rise lubrication, increase toughness and
Increasing the effect of brightness, CPE is PVC stabilizer；Above-mentioned raw materials is prepared by the proportioning of science, is ensureing guardrail
Toughness, on the basis of intensity, control the content of polyvinyl chloride resin below 50%, effectively reduce the cost of guardrail, same to time
Brightness is higher.2, PVC guardrail has the intensity more much better than timber and toughness, has enough intensity, simultaneously simple installation, fast
Victory, for the seating meanses such as welding, can use plug-in connection part to install, be greatly improved installation rate, this
Kind of connection make guardrail easily on slope or irregular ground with arbitrarily angled, install along different directions.3, PVC guardrail
More tough and tensile than timber, and more full of elasticity and high-impact performance, harmless to people, animal, also will not protect as steel, ferrum even if being not intended to touch guardrail
Hurt sb.'s feelings like that in hurdle.4, service life is long, PVC guardrail ensure that service life is more than 20 years, simultaneously as have employed titanium dioxide
Etc. ultraviolet-resistant absorbent, make guardrail to fade, turn to be yellow, peel, dry and decayed, ftracture, bubble, warpage and damaging by worms, in addition due to
Being not required to safeguard, eliminating the trouble of maintenance management and make integrated cost, the maintenance cost in later stage is far below wooden and iron and steel guardrail.
5, it is beneficial to recycle, the guardrail that will recycle, after pulverizing, direct and mix particles, it is transported to firmly determine in machine, effectively
Cost-effective, reach the purpose of sustainable production.
The preparation method of PVC guardrail, comprises the following steps:
Step one, dispensing mix: each constituent weighed by weight, put into high speed mixer carries out mixing 20 ~
30min, mixing temperature rises to 120 DEG C；
Step 2, once plasticizing: step one gained mixed material is sent into heating plasticizing in Plasticator, and the rotating speed of Plasticator is 18
~ 20r/s, plasticizing rate, 70 ~ 80%, extrudes particle；
Step 3, secondary plasticizing: be delivered to firmly determine in machine by the particle of step 2 gained, the rotating speed firmly determining machine is 18 ~ 20r/s,
Plastifying material is obtained after extruding hot briquetting；
Step 4: cooling, molding: the plastifying material of step 3 gained is air-cooled through blower fan, is cooled to room temperature, obtains guardrail sectional material.
Beneficial effects of the present invention: by twice plasticizing forming, puts into Plasticator after high-temperature stirring intensification for the first time and moulds
Metaplasia is produced, and plasticizing rate, when 70 ~ 80%, extrudes particle, and the particle of extrusion is transported to firmly determine in machine, and secondary plasticizing is plastified
Material, is fabricated to the guardrail of various model after cooling afterwards.The advantage of twice plasticizing forming is: breach tradition once
The technique of straight forming material after plasticizing forming, makes that the section bar after processing is elegant in appearance, Surface of profile is smooth, brightness and glossiness
Higher, reflective is effective, meets consumer's aesthetic requirement to guardrail；The same density adding plastifying material constantly, makes this
Product hardness, toughness have the highest lifting.
Preferably, when step one batch mixing, add the organic pigment of 0.015 ~ 0.5 part.Organic pigment includes red pigment
And yellow uitramarine, processing color beautiful, bright-coloured, smooth surface becomes clear, and is the guardrail product of most decoration functions, to environment
Decorative effect is more preferable.
