Abstract

The invention provides an impact-resistant PP-R tube, comprising the following components in parts by weight: 100 parts of PP-R master batches and 1-10 parts of nanoparticles loaded with alpha nucleating agents on surfaces. According to the impact resistant PP-R tube provided by the invention, the nanoparticle-loaded alpha nucleating agents are added, so that the PP-R crystal is relatively perfect in shape, relatively small in grain, and convenient to mold and process; and the mechanical property is comprehensively improved.

Description

One has impact-resistant PP-R pipe and preparation method thereof
Technical field
the present invention relates to polypropylene pipe field, more specifically, relate to one and there is impact-resistant PP-R pipe and preparation method thereof.
Background technology
PP-R pipe has the advantages such as heat preservation energy-saving, heat-resisting, the oxidative stability of environmental protection and excellence and sanitation performance, and compared with other cold hot water piping, PP-R pipeline is moderate, and cost performance is high, is applicable to the domestic market requirement.
At present, the popularization of China PP-R pipe is subject to the restriction of several factor: the resin dedicated performance of (1) domestic PP-R is not good, and the domestic degree of raw material is not high.(2) low-temperature flexibility of PP-R pipe is poor.Because low-temperature impact-resistant performance is poor, at low ambient conditions, can there is low temperature brittleness in PP-R pipe, therefore damage very easily in transit.
Summary of the invention
in order to improve PP-R pipe impact resistance at low temperatures, first the present invention provides a kind of impact-resistant PP-R pipe, it is characterized in that, by weight, comprises following component,
PP-R master batch 100 parts,
Area load has nanoparticle 1-10 part of α nucleator.
Described area load have the preparation method of the nanoparticle of α nucleator for by α nucleator and nanoparticle in grinding in ball grinder, make nucleator in nanoparticle surface load by physical method.
Described nanoparticle is calcium carbonate, talcum powder, wollastonite or ZnOw.
Described α nucleator is dibenzal sorbitol.
By weight, look female 1-5 part is also comprised.
The preparation method of the PP-R pipe of above-mentioned impact is provided further, it is characterized in that, raw material mixing is adopted extruder for shaping.
PP-R pipe of the present invention has dosed nanometer particle load α nucleator, and make the crystal habit of PP-R more perfect, crystal grain is less, and forming process is convenient, and mechanical property is improved comprehensively.
