Problems solved by technology

Moreover, when its microscopic polycrystalline silicate sheet is combined with rubber, it can bring certain reinforcing properties to the mixed colloid, but if Imon clay is used alone, the effect of reinforcing rubber is not as good as that of carbon black and white carbon. Black, and after the filling number of Emon clay in the rubber system reaches 25 parts, the tear strength, elasticity and other properties of the rubber system will decrease significantly, and the tensile strength of the Emond clay filled rubber without intercalation treatment The strength is not high, but the layered polysilicate structure of Imon clay after intercalation process gives good characteristics

Abstract

The invention discloses a preparation method for preparing dual composite natural rubber from illite-smectite clay intercalated silica. The method mainly comprises the steps of processing a nano-scale illite-smectite clay material by adopting an intercalating agent, further damaging a close and ordered packed structure of laminar silicate to form layered basic units by peeling, then mixing and melting with a suspension mixed with natural latex and silica, uniformly dispersing in a polymer matrix, finally realizing intercalation composition of a natural rubber high polymer, silica and layered silicate lamellae on nano scale and completing the manufacturing of a finished product through continuous production.

Description

technical field [0001] The invention relates to a method for preparing multiphase composite natural rubber in the field of rubber, in particular to a method for intercalation modification of Imon clay and double compound filling of natural rubber with inorganic filler. Background technique [0002] Natural rubber is a rubber strain widely used in the rubber field. It is different from the downstream products of petroleum refining such as butadiene rubber and styrene-butadiene rubber. Natural rubber comes from natural plant extraction. It has the advantages of green resources. When natural rubber is applied in downstream product enterprises (such as tire industry, etc.), it is necessary to add reinforcing materials such as carbon black and white carbon black to improve the strength of rubber products and reduce costs. Among them, white carbon with silica as the main component After being filled with rubber, black has the functions of reducing tire rolling resistance, heat ge...
