Description
Technical field
The invention belongs to board technology field, in particular to the dedicated toughening high-strength weather-proof PVC composition of a kind of plate and
Preparation method.
Background technique
In plate application field, polyvinyl chloride (PVC) plate is due to it is with excellent waterproof, sound insulation and thermal insulation property
It is widely used in building, squeezes out processing aspect.PVC board is mainly by the processing aids such as polyvinyl chloride resin and plasticizer, stabilizer
It after cooperation, is squeezed out or is rolled and be process, wherein to squeeze out based on processing.It will be appreciated, however, that since PVC molecule chains
There is more unstable α-cl in structure, degradation is easy in machine-shaping, and then lead to PVC product existing defects, under room temperature
The toughness of product is poor, and impact strength is lower, and weather resistance is poor in long-term use process outdoors, easily by sunlight
Ultraviolet light destroys and causes the metachromatisms such as jaundice.Thus in order to solve the problems, such as PVC structure, there are latent defects, often at present
It is the auxiliary additive that addition contains heavy metal " lead " in PVC board process, but the addition of " lead " will necessarily be big
Increase the risk to cause damages to surrounding enviroment and human body greatly.
Summary of the invention
The technical problems to be solved by the present invention are: it is high to overcome the deficiencies of the prior art and provide a kind of dedicated toughening of plate
Weather-proof PVC composition of intensity and preparation method thereof, to solve general PVC board, there are poor toughness, impact strength difference and weatherabilities
The defects of insufficient problem.
The technical solution adopted by the present invention to solve the technical problems is: a kind of dedicated toughening high-strength weather-proof PVC of plate
Composition, which is characterized in that parts by weight composition are as follows: 100 parts of polyvinyl chloride resin, 4 ~ 6 parts of stabilizer, 3 ~ 10 parts of titanium dioxide, anti-impact clicks to change
5 ~ 16 parts of agent of property, 1 ~ 3 part of processing aid, 0.5 ~ 2 part of antioxidant, 3 ~ 12 parts of calcium carbonate, 0.1 ~ 1 part of lubricant, pigment 0.01 ~
0.1 part.
Preferably, the polyvinyl chloride resin degree of polymerization is 700 ~ 1300.
Preferably, the stabilizer is stabilizer.
Preferably, the titanium dioxide is rutile-type.
Preferably, the processing aid is novel linear PVC processing aid.
Preferably, the antioxidant is four [β-(3,5- di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol esters.
Preferably, the calcium carbonate is calcene.
Preferably, the lubricant be stearic acid lubricant and high density oxidized polyethylene wax in any one or
More than one combination.
Preferably, the toner pigment is environmental-friendly pigment ultramarine.
Preferably, the stabilizer is rare earth calcium zinc stabilizer, and the selection of stabilizer is to influence plate
One of the factor of material safe handling, and the present invention has selected nontoxic rare earth calcium zinc stabilizer, and heavy metal is free of in composition,
Effectively prevent harm of the heavy metal to human body and the pollution to surrounding enviroment.
Preferably, the anti-impact modifier is ACR and CPE, and the chain structure phase of the nucleocapsid structure of ACR and CPE
Mutually intersect, the toughness of PVC board, anti-impact modifier ACR and CPE are greatly improved on the basis of guaranteeing PVC board tensile strength
Collaboration use, further increase the performance of PVC board.
Rare earth calcium zinc stabilizer and the [β-(3,5- di-tert-butyl-hydroxy phenyl) of antioxidant four are selected in the present invention
Propionic acid] pentaerythritol ester addition, not only preferably improve the weatherability of PVC board, and avoid and generate sulfide staining
Problem；Furthermore the addition of novel linear PVC processing aid, not only substantially increases the mobility of PVC, increases in production and processing
The production stability of PVC, and ensure that in being used for a long time the metachromatism that turns to be yellow will not occur for PVC board, substantially improve PVC
The weatherability of plate.
The present invention provides a kind of preparation method of dedicated toughening high-strength weather-proof PVC composition of plate, comprising the following steps:
Hot mixer is put into according to the weight percent of each component, after precise to carry out mixing and being made mixture, works as Hot mixer
Ingredient is discharged into cold mixing machine when temperature reaches 115 ~ 120 DEG C, then discharge is carried out when cold mixing machine temperature is 50 DEG C, obtains
Finally PVC dry blend is added to conical double screw extruder for PVC dry blend, is moulded at a temperature of 160-190 DEG C by extruder
Change and squeeze out, oral mold forming, stock mould cooling and shaping draws and is cut into PVC board.
The utility model has the advantages that the PVC board prepared of the present invention its with good toughness, excellent impact resistance, good
Weatherability and corrosion resistance；Simultaneously the PVC board prepared of the present invention its be not only free of heavy metal, asepsis environment-protecting, Er Qieqi
Low manufacture cost, simple production process are easy to large-scale industrial production, improve the real value of PVC board.
