Abstract
The invention discloses extruded low-foaminess PVC section bar. The extruded low-foaminess PVC section bar comprises following ingredients, by mass, 100 parts of PVC, 0.2 to 0.8 part of sodium bicarbonate, 1 to 3 parts of calcium stearate, 1 to 4 parts of DOP, 2 to 6 part of DBP, 5 to 10 parts of CPE, 1 to 5 parts of dimethicone, 1 to 3 parts of tribasic lead sulfate, 0.5 to 1 part of dibasic lead phosphate, 1 to 4 parts of a modifier, 1 to 8 parts of calcium carbonate, 0.5 to 1 part of zine stearate, and 0.5 to 1 part of lead stearate. Product relative density is 0.93, bending strength ranges from 60 to 65MPa, impact strength ranges from 28 to 30kJ/m<2>, tensile strength ranges from 30 to 35MPa, and elongation ranges from 9 to 12%. The extruded low-foaminess PVC section bar possesses acid and alkali resistance, and wear resistance, and can be used for replacing existing materials continuously; and large-scaled production can be realized.
Description
Technical field
The application belongs to plastic material field, relates in particular to one and extrudes low foaming PVC section bar.
Background technology
PVC section bar is to be added after various functional agents by polyvinyl chloride resin, through industry and the life PVC product of high temperature extrusion moulding; By performance, can be divided into hard and soft two kinds.Hard PVC section bar is used for building aspect, as made PVC door and window, PVC floor, pvc pipe material etc.; Flexible PVC section bar is for PVC flexible pipe, feeder cable etc., and the PVC section bar that has added functional agent has anti-aging, uvioresistant, corrosion-resistant, intensity is high, low price, insulation and heat-proof quality are good, can part substitution of Al section bar, steel etc.
PVC section bar product has experienced introduction period and high-speed development period, from the time, can be defined as respectively about the twentieth century eighties-the mid-90 and nineteen ninety-five-2002 year.After 2003, PVC section bar industry has entered the transitional period.In the introduction period of product: manufacturer generally pursues low cost, simplified door-window section bar section, calcium carbonate filled in a large number in formula, cause product performance very low, the appearance of a lot of quality problems has affected the popularization of product, along with the development of social city, technicalization, hommization, designs a kind of flexural strength high, the high PVC section bar of shock strength, to meet the need of market, is very important.
Summary of the invention
the technical problem solving:
The application extrudes low foaming PVC shape bending intensity and the technical problem such as shock strength is low for existing, provides one to extrude low foaming PVC section bar.
technical scheme:
One extrudes low foaming PVC section bar, consists of, take mass fraction representation as PVC100 part following raw materials according; Sodium bicarbonate 0.2-0.8 part; Calcium stearate 1-3 part; DOP1-4 part; DBP2-6 part; CPE5-10 part; Dimethyl silicone oil 1-5 part; Tribasic lead sulfate is 1-3 part; Dibasic lead phosphite is 0.5-1 part; Properties-correcting agent 1-4 part; Calcium carbonate 1-8 part; Zinic stearas 0.5-1 part; Lead stearate 0.5-1 part.
As a preferred technical solution of the present invention: described in extrude low foaming PVC section bar, its moiety, take mass fraction representation as: its composition take mass fraction representation as PVC100 part; 0.5 part of sodium bicarbonate; 2 parts of calcium stearates; DOP2.5 part; DBP4 part; CPE7.5 part; 3 parts of dimethyl silicone oils; Tribasic lead sulfate is 2 parts; Dibasic lead phosphite is 0.8 part; 2.5 parts of properties-correcting agent; 4.5 parts, calcium carbonate; 0.7 part of Zinic stearas; 0.75 part of lead stearate.
As a preferred technical solution of the present invention: described properties-correcting agent adopts ACR.
beneficial effect:
One of the present invention is extruded low foaming PVC section bar and is adopted above technical scheme compared with prior art, has following technique effect: 1, product relative density 0.93, flexural strength 60-65MPa; 2, shock strength 28-30kJ/m
2; 3, tensile strength 30-35MPa, elongation 9-12%; 4, product acid and alkali-resistance, wear-resisting, can the not division of history into periods of widespread production replace current material.
