Abstract
The invention relates to a modification formula of PVC (polyvinyl chloride) plastic. The modification formula of the PVC plastic comprises the following components: 75-78% of PVC resin, 6-10% of activated calcium carbonate, 2.5-4% of compound stabilizer, 1-1.2% of ACR process additive, 0.2-0.4% of paraffin, 0.2-0.4% of stearic acid, 2-2.4% of titanium dioxide, 0.1-0.12% of chlorination resisting agent, 0.02-0.04% of brightening agent, 4.5-5% of CPE (chlorinated polyethylene) flexibilizer and 1.2-2% of aluminum powder. The PVC plastic prepared from the modification formula disclosed by the invention has good acid and alkaline resistances, does not generate a situation of yellowing and hydrolyzing after being exposed to the sun and rain year after year, and has longer service life compared with other material products.
Description
Technical field
The invention belongs to the plastic material processing industry, particularly a kind of modified formula of PVC plastic cement.
Background technology
In the plastic material processing industry, the processing of PVC plastic cement and use very extensively, especially aspect plastic door, window, but in process of production, following point all can be run into by a lot of manufacturing enterprises:
1, for improving competitive market power, reduce door, window plastic irregular profile production cost, enterprise of large section all is the consumption that increases former processing aid calcium carbonate.But the requirement that the shock resistance of product is difficult to be up to state standards.
2, domestic auxiliary agent kind for the production of plastics is more, enterprise is also a lot, the ability of raw materials quality does not detect in most of enterprise that produces plastic material at present, and the producer that much produces auxiliary agent increases because the factors such as increasing price of raw materials and cost of labor cause cost.And the quality of the quality of PVC plastic cement and prescription has directly and contacts.
?
Summary of the invention
The technical problem to be solved in the present invention provides a kind of modified formula of novel PVC plastic cement, and the PVC plastic cement that adopts this prescription to process can well combine with acrylic.
A kind of modified formula of PVC plastic cement, the modified formula of this PVC plastic cement is: the prescription % of polyvinyl chloride resin 75～78%, activated Calcium carbonate 6～10%, one package stabilizer 2.5～4PVC plastic cement, ACR process auxiliaries 1～1.2%, paraffin wax 0.2～0.4%, stearic acid 0.2～0.4%, titanium dioxide 2～2.4%, anti-chlorine agent 0.1～0.12%, whitening agent 0.02～0.04%, CPE toughner 4.5～5%, aluminium powder 1.2～2%.
The PVC plastic cement acid-proof alkaline that adopts prescription of the present invention to process is good, can be because of not exposing to the sun and rain year in year out, and produce the phenomenon of yellowing and hydrolysis, and to compare with other material product, the life-span is long.
?
Embodiment
The quality of PVC plastic cement is mainly determined by following four aspects:
(1) prescription: prescription is the assurance of making the high-quality section bar.If the section bar prescription is unreasonable or the unstable bad or defectiveness of raw materials quality of use, the section quality of producing is difficult to guarantee.
(2) choose high quality raw material and auxiliary agent: the section bar prescription is comprised of multiple former auxiliary, good prescription again, if the former auxiliary quality of using is unstable, even only have a kind of raw material defective, the quality that all directly affects section bar by the gross no matter formulating of recipe how good, if raw material and auxiliary agent are unreliable, wherein a kind ofly there is problem also can make section quality influenced or defective even only have.
(3) equipment and mold: equipment comprises batching, mixing equipment, section bar extrusion apparatus for production line and utility appliance, pipeline system etc.
(4) production technique of section bar wants correct: the production technique of section bar comprises work program from the former full scale production process of expecting the section bar finished product, processing parameter, working method main points, precaution etc.
The invention provides a kind of modified formula of novel PVC plastic cement, the modified formula of this PVC plastic cement is: polyvinyl chloride resin 75～78%, activated Calcium carbonate 6～10%, one package stabilizer 2.5～4%, ACR process auxiliaries 1～1.2%, paraffin wax 0.2～0.4%, stearic acid 0.2～0.4%, titanium dioxide 2～2.4%, anti-chlorine agent 0.1～0.12%, whitening agent 0.02～0.04%, CPE toughner 4.5～5%, aluminium powder 1.2～2%
Adopt the present invention to fill a prescription through batching, batch mixing, feeder, extrusion moulding, automatically cut plate, form at last needed PVC plastic cement.This PVC plastic cement combines with acrylic and is applied on refrigerator doorframe and the strip of paper used for sealing together, and is not only with low cost, and good looking appearance.
The PVC plastic cement that adopts the foregoing invention prescription to process has the following advantages:
1, good weathering resistance: very strong to physical environment adaptability, even at sun exposure, wind and weather its performance is changed for a long time, ageing resistance is good, also can feel at ease to use outdoor
2, processing characteristics is good: not only suitable mechanical workout but also easily thermoforming
3, excellent over-all properties: the PVC plastic cement that adopts present method to process does not need to spray and secondary processing again, i.e. environmental protection has reduced again production cost, and has the comprehensive of excellence.
4, nontoxic: even harmless with people's Long Term Contact, the gas that produces when burning does not in addition produce toxic gas yet.
