Abstract
The invention discloses ultrafine calcium carbonate and talcum powder filled polypropylene, which consists of the following components in parts by weight: 100 parts of homo-polypropylene, 4-8 parts of calcium carbonate, 15-25 parts of talcum powder and 0.25-0.5 part of composite coupling agent, wherein the composite coupling agent consists of the following components in percentage by weight: 40-60 percent of isopropyl tri (dioctylphosphate) titanate and 40-60 percent of dipolymer diisooctyl acid phosphate magnesium stearate. The ultrafine calcium carbonate and talcum powder filled polypropylene disclosed by the invention has higher tensile strength and impact strength.
Description
Technical field
The present invention relates to a kind of acrylic plastering, relate in particular to a kind of calcium carbonate superfine powder talc powder filled polypropylene.
Background technology
Polypropylene, English name: Polypropylene is called for short PP, and CAS accession number: 9003-07-0 is a kind of thermoplastic resin that is made by propylene polymerization.Polyacrylic chemical stability is fine, and is all more stable to various chemical reagent, and polypropylene is fit to make various chemical pipelines and accessory, and anticorrosion ability is good.
Summary of the invention
For above shortcomings in prior art, technical problem to be solved by this invention is to provide a kind of calcium carbonate superfine powder talc powder filled polypropylene.
Technical problem to be solved by this invention is achieved by the following technical solution:
A kind of calcium carbonate superfine powder talc powder filled polypropylene is made of by weight following component: 100 parts of homo-polypropylene, and calcium carbonate 4-8 part, talcum powder 15-25 part, composite coupler 0.25-0.5 part,
Described composite coupler is comprised of following compositions in weight percentage: sec.-propyl three (dioctyl phosphoric acid acyloxy) titanic acid ester 40-60% and dimerization di (isooctyl) phosphate Magnesium Stearate 40-60%.
Sec.-propyl three (dioctyl phosphoric acid acyloxy) titanic acid ester and dimerization di (isooctyl) phosphate Magnesium Stearate are mixed, can make this composite coupler.
Adopt industry universal method that composite coupler is mixed with calcium carbonate and talcum powder, then mix with homo-polypropylene, melting mixing, extruding pelletization can make.
Calcium carbonate superfine powder talc powder filled polypropylene of the present invention has higher intensity and the shock strength of drawing high.
