Abstract
The invention relates to a preparation method of a surface-modified attapulgite-reinforced rubber material. The material is characterized in substantially improved tensile strength, 300% elongation strength and tear strength, short vulcanization time, and good vulcanization crosslinking effect. The surface-modified attapulgite-reinforced rubber comprises the raw material components of, by mass, 50-200 parts of natural rubber, 2-5 parts of zinc oxide, 1-3 parts of stearic acid, 1-2 parts of sulfur, 1-3 parts of an accelerator DM, 1-3 parts of an accelerator CZ, and 30-100 parts of modified attapulgite.
Description
Technical field
The present invention relates to the preparation method of a kind of surface modified concave soil reinforced rubber material.
Background technology
Attapulgite (being called for short recessed soil, OT) is the rich Mg aluminate mineral of a kind of more rare porousness key layered hydrous, and its chemical formula can be expressed as Mg usually
5[Al] (Si
8o
20) (OH)
2(OH

4.4H
2o.The attaplgus clay resources all having rich reserves is economized in China Jiangsu, Anhui etc.Recessed soil can be used as sorbent material, loading material of rubber, drilling mud, thickening material, binding agent and fodder additives etc.Research shows the hydroxyl of recessed soil surface containing polarity, therefore it is on duty mutually with the affinity of nonpolar organic polymer.So recessed soil can not reach the well potent fruit of step in rubber, belong to inert filler.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, devise a kind of surface modified concave soil reinforced rubber material, modified attapulgite has obvious reinforcing effect to be a kind of new type rubber active filler to rubber, namely by carrying out organic modification to recessed native surface, its consistency in rubber and filler effect is improved.
The present invention is achieved using the following method.
The preparation method of modified attapulgite is: at 20 DEG C, and PH is 6.3, and properties-correcting agent (self-control) initial concentration is under the condition of 9.4mmol/L, and control solid-liquid than being 17g/mmol, modifier content is 1.9%, and the reaction times is 1h, obtained modified attapulgite.
The preparation method of surface modified concave soil reinforced rubber is: the mechanically mixing of carrying out modified attapulgite and various Synergist S-421 95 and rubber with mill, and cross-linked rubber sample vulcanizing press, 150 DEG C of sulfurations, is then carried out sulfuration by rubber unvulcanizate, obtained reinforced rubber.
Advantage of the present invention is:
1, modified attapulgite has the acceleration vulcanization of rubber, strengthens the effect of vulcanization crosslinking.
2,300% of the rubber that the more unmodified recessed soil of natural rubber that modified attapulgite is filled is filled is stretched surely, stretch and tearing toughness is all significantly improved.
Further illustrate of the present invention:
Embodiment 1
