Description

A kind of high gloss environment-friendly PVC section bar and preparation method thereof
Technical field
The invention belongs to PVC profile, be specifically related to a kind of high gloss environment-friendly PVC section bar and preparation method thereof.
Background technology
Because lead salt belongs to heavy metal human health being had to harm, along with people are to the raising of lead salt recognizing dangers, from the eighties in last century, American-European-Japanese proposition in succession prohibits the use the requirement of lead salt, cadmium salt class stablizer.Decree has all been put into effect in the countries and regions such as the U.S., Japan, Canada, South America, forbids or limit the use of lead, cadmium series products in PVC product.European Union has also concluded lead salt by European stablizer Vasep (ESPA) and has substituted action, all will eliminate Lead salt thermal stabilizer before 2015.
In section bar production, countries in the world research and develop lead, tin substitute one after another.The use of country variant and regional thermo-stabilizer has very large difference.First the U.S. make important progress on organic tin stablizer, goes on the main developing direction using organic tin stablizer, and European Countries is then devoted to development nontoxic calcium zinc class one package stabilizer.China be by continue to use or foreign imitation formula and progressively develop, main adopt the use calcium-zinc composite stabilizing agent similar with Europe to substitute lead salt stabilizer.
Current Environmental Protection in China calcium zinc class one package stabilizer is still in Continual Improvement, and the continuous seepage cycle of operation extends to some extent, but the section bar apparent masses such as glossiness still comparatively complex lead salt stabilizer gap to some extent.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of high gloss environment-friendly PVC section bar, surface gloss obviously promotes, and smooth exquisiteness.
Present invention also offers a kind of preparation method of high gloss environment-friendly PVC section bar.
A kind of high gloss environment-friendly PVC section bar provided by the invention, comprises the material of following weight part:
The described PVC polymerization degree is 1000, the SG-5 type PVC that can obtain for ethylene process or calcium carbide route.
Described stabilizer Environment-friendlycalcium calcium zinc stabilizer.
Described titanium dioxide is rutile-type.
Described processing aid is acrylic polymer.
Described weighting agent is light active calcium carbonate.
Described toning agent be pure aluminium silicate containing sulfur compound.
Described lubrication conditioning agent is high-density oxidized polyethlene wax.
The preparation method of a kind of high gloss environment-friendly PVC section bar provided by the invention, comprises the following steps:
(1), polyvinyl chloride (PVC) 100 parts, stabilizer 3.5-6 part, titanium dioxide 5-12 part, shock resistance ACR properties-correcting agent 4-7 part, shock resistance CPE properties-correcting agent 4-8 part, processing aid 0.5-2 part, weighting agent 5-12 part, lubrication conditioning agent 0.02-2.0 part, toning agent 0-0.1 part are dropped into Hot mixer mixing, temperature is drained into after reaching 120 DEG C in cold mixing machine, coldly mix to 40-45 DEG C, after roots blower and reciprocating sieve remove foreign matter, enter storage deposit tank, homogenizing 24 hours, obtains PVC dry blend;
(2), PVC dry blend is added twin screw extruder hopper, utilize screw rod rotary presser mode, continuously the molding materials plastified is got into extrusion die from the machine barrel of forcing machine, melting material is shaped to the continuum similar with Oral incision by machine head port mould, is pulled out continuously by moulded products with towing mechanism from mould, carries out cooling and shaping simultaneously, overlay film, cutting, through packing after the assay was approved, warehouse-in.
Current domestic PVC profile formula mainly uses CPE as impact modifier, has the features such as the low and strong adaptability of use cost.CPE itself is in chain-like structure, and work in-process forms cubic network, and PE segment soft in molecular chain provides toughness; The segment that similar PVC is chlorinated, consistency with PVC is provided, the performance of CPE modified PVC effect and the formational situation of network structure have much relations, network-type impact modifier obtains the work range relative narrower of optimum physical mechanical property, shock strength and change of processing conditions mixing with PVC compound is comparatively responsive, simultaneously the declining by a big margin of tensile strength and modulus and heat-drawn wire.
The material of a kind of shell-core structure of anti-impact ACR properties-correcting agent, kernel is the elastomerics of lightly crosslinked butyl acrylate, rubber like; Shell is methyl methacrylate, provides the excellent compatibility with PVC.ACR absorbs impact energy suffered by PVC by the elastomerics of stratum nucleare, therefore, the application of ACR is less by the impact of processing conditions, and work range is wider, disperse more even, effectively can promote low-temperature impact-resistant performance and the apparent mass of PVC plastic section bar.Elastic body toughening PVC can improve toughness and the processing characteristics of PVC product, but this improvement condition premised on the tensile strength of sacrificing PVC and resistance toheat often.
Due to above reason, improve the toughness of PVC on the basis selecting anti-impact ACR properties-correcting agent and CPE to work in coordination with to be used in and to ensure the superperformances such as PVC tensile strength, the advantage of these two kinds of impact modifiers complementary, further raising improves some performances of PVC profile.
Middle-high density oxidized polyethlene wax of the present invention: there is rate of extrusion and improve, keep product surface high gloss.Not metal ion, prevents from separating out.Postpone gathering of heat of friction, improve the characteristics such as thermostability at high temperature, for extruding, injection moulding, prolongs pressure and plastic uptake, the industries such as blowing.To in PVC outer lubrication compare balance, at hard transparent, add its oilness of oxidized polyethlene wax in opaque PVC formula and be better than other lubricants.Playing outer cunning is in the present invention that main having concurrently in part slides regulating effect.
Compared with prior art, the PVC profile surface gloss that the present invention produces obviously promotes, and smooth exquisiteness; Not containing heavy metals such as Ba, Cd and Pb in composition, asepsis environment-protecting, and be not vulnerable to sulfide staining; Light fastness aging is excellent, and performance can promote about 20%.Solve Traditional Environmental-protection calcium zinc stabilizer formula and produce the problems such as section bar surface gloss is relatively poor, and feel is fine and smooth not.
