Description
Technical field
The invention belongs to pyrophillite high value added utilization and organic processing and its corresponding application with inorganic composite materials
Field, and in particular to a kind of raw particles and its system of pyrophillite fine powder and the compound electric wire and cable jacket material of polyvinyl chloride
Preparation Method.
Background technique
Currently, efficient utilize of the protection of ecological environment and natural resources is the hot spot and difficult point put in face of scientific research personnel
Problem, the environmentally protective theories such as energy conservation, consumption reduction are gradually goed deep into people daily production and life, and " five water are made altogether ", " air is net
Relevant agenda is gradually put in the environmentally friendly behave such as change ".For traditional Plastics Industry, it is based on its material intrinsic attribute
And its for source, there is the limitation or drawback applied as follows, be embodied in: firstly, it is more difficult to degrade in view of conventional plastic,
Its " white pollution " problem generated brings immeasurable negative effect to ecological environment.Secondly, because organic polymer its
Source material is mainly petroleum, and petroleum is then a kind of non-renewable natural resources, with a large amount of exploitation and by complicated
Reaction generate series derivative products.On the one hand, petroleum resources cause its reserves increasingly reducing in continuous be consumed.
On the other hand, the series derivatives product of petroleum while being consumed and generates a large amount of noxious products, such as sulphur, nitrogen class sour gas
Body, oxide of carbon etc., equally bring immeasurable harm to the natural environment that we depend on for existence, so that " greenhouse effect
Answer ", the environmental problems such as " acid rain " " haze " gradually annoying the daily production and life of people.Again, with regard to the application of material
For performance, the polymer of pure component is solely used to prepare associated plastic product for raw material, application performance or because of material
Attribute itself is limited, and the service performance such as usability such as mechanical strength, ageing-resistant, sun-proof, wear-resisting of relevant plastic products are caused
Can be poor, and then hinder its specific application.Therefore, related organic polymer is at it in application, relatively mostly using with inorganic material
The function and service of organic-inorganic material is carried out as filler, using organic polymer as carrier, and then application and preparation is had excellent performance
End product.Currently, by calcium carbonate fine powder be inorganic filler, by taking PVC is the wire and cable jacket material of organic carrier as an example,
With performances such as more excellent insulation performance, ageing-resistant, wear-resisting and elongation at break, thus it is widely used in daily life
Production and sphere of life.However as previously mentioned, with a large amount of exploitations of calcium carbonate natural resources, natural mineral resources are increasingly deficient
While weary, CR Critical destruction also is brought to ecological environment and natural vegetation.
Pyrophillite, is a kind of hydrous alumino silicates layered clay mineral, and theoretical chemistry ingredient is Al2O328.3%,
SiO266.7%, H2O 5.0%, molecular formula Al2[Si4O10](OH)2Or Al2O3·4SiO2·H2O is a kind of relatively abundant
Natural mineral resources, because it is with excellent high temperature resistant and the characteristics such as resistant to chemical etching, and be widely used in coating, pottery
The fields such as porcelain, rubber, transmission medium and refractory material.At the same time, mostly given in view of current pyrophillite with rough machined powder
It utilizes, added value is lower, and the exploitation and its industrial upgrading for seeking pyrophillite high value added product have become investigation of materials field
Hot topic.Using pyrophillite as the supplement of calcium carbonate or strategy alternatives, and as wire and cable, plastics, rubber, nonwoven
Its biggish application place to go and higher industry then may be implemented in the inorganic filler of the polymer composites industry such as cloth, pyrophillite
Added value.

30min, and the temperature of system is made to be maintained at 90~110 DEG C, obtain modified organic carrier mixed material B；
S2: A, B and antioxidant are stirred 20-60min with the speed of 600~800r/min, and protect the temperature of system
It holds at 110~160 DEG C, obtains mixed material C；
S3: said mixture material C is plasticized extruding pelletization through twin-screw-single screw rod, and then it is fine to obtain high performance pyrophillite
The raw particles of powder and polyvinyl chloride electrical wire and cable sheath material.
