Abstract
The invention discloses modified bentonite for a thermoplastic elastomer wire/cable material and a preparation method of the modified bentonite. The modified bentonite is prepared from the following raw materials in parts by weight: 46-54 parts of bentonite, 4-8 parts of dimethyl fumarate, 15-20 parts of ketoaldehyde resin, 3-6 parts of candelilla wax, 5-10 parts of heavy calcium carbonate powder, 4-6 parts of nanometer magnesium titanate, 5-10 parts of petroleum coke powder, 3-5 parts of aluminium isopropoxide, 2-4 parts of antimony sulfide, 1.5-2.5 parts of diallyl bisphenol A, 1-2 parts of isoamyl p-methoxycinnamate, 2-3 parts of tetramethyl tetravinyl cyclotetrasiloxane, 1-2 parts of N,N'-diphenyl-1,3-propane diamine and 2-4 parts of an assistant. After the bentonite is subjected to modification treatment, the compatibility of inorganic particles and an organic polymer matrix is improved, phase separation is reduced, dispersion of the bentonite in the organic phase is facilitated, the filling performance and the reinforcing effect of bentonite are improved, the impact strength and the tensile strength of the composite material are greatly improved, the mechanical property of the composite material is improved, meanwhile, the heat resistance, the ageing resistance, the corrosion resistance, the oil resistance and the like of the composite material can be improved by virtue of filling of the modified bentonite.
Description
Technical field
The present invention relates to a kind of thermoplastic elastomer electric wire and cable material modified alta-mud and preparation method thereof, belong to mineral filler technical field.
Background technology
Wilkinite profit soil has another name called amargosite, otaylite, and sometimes also claim white clay, be that a kind of performance is very excellent, economic worth is higher, the clay resource that range of application is wider.Wilkinite to be a kind of with montmorillonite be main component moisture clay pit.Wilkinite, due to the mineral structure of uniqueness and crystal chemistry character, has many very excellent performances, is widely used in the mineral filler of the polymer composites materials such as plastics, rubber.But existing wilkinite poor compatibility not only and between organic polymer, and it is lower to fill function, makes bentonitic range of application have limitation.Therefore, certain modification must be carried out to it.
