Method.
Background technique
It is well known that PVC pipeline originates from the thirties in last century, it is an application away from modern existing more than 80 years history
The product of relative maturity is still the maximum plastic conduit of dosage, accounts for about 60% or so of entire plastic conduit market, mistake so far
It goes in 50 years, China's PVC pipeline is supplying water, and irrigates, and building, the fields such as chemical industry are used widely, but due to its material itself
Performance deficiency, also there are a series of engineering accident problems.
PVC pipeline has following defect also to need to be further improved: its toughness is insufficient, shock resistance, thermostabilization and anti-cracking performance
Difference is easy to happen brittle break when by extraneous impact energetically, be easy to cause breakage in actual application.
Summary of the invention
In order to overcome above-mentioned technical problem, the purpose of the present invention is to provide a kind of frost-cracking-preventing feed pipe formula and its systems
Preparation Method, prepared frost-cracking-preventing feed pipe have excellent wearability, thermal stability, impact strength, the performances such as resistance to ag(e)ing.
By the present invention in that being acidified kaolinic purpose with dilute hydrochloric acid is the impurity in order to remove its internal gutter, and can
Effectively kaolin surface to be made to organise, prepared filler slurry is more effectively dispersed between PVC masterbatch, solves
Filler slurry disperses non-uniform problem between PVC masterbatch, so that the stability of material each section reaches consistent.
Template is added in the present invention in presoma, passes through power the effects of ionic bond, Van der Waals force and hydrogen bond, guiding material
Internal order self assembly, being formed has densification, and the material internal structure of norm structure solves material internal integrally random row
Sequence helps to improve the toughness of material, shock resistance etc. so that material internal structure is more regular.
In the present invention prepared composite thermal stabilizer have the characteristics that be not easy to be precipitated, stability it is good, solve finished product
The poor problem of thermal stability.
