Abstract
The present invention relates to gross rubber for tires with high abrasion resistance and a preparation method thereof. Gutta-percha is blended with natural rubber, styrene-butadiene rubber, nitrile rubber, polybutadiene rubber, etc. for vulcanization, and the gross rubber for the tires with high abrasion resistance is obtained through changing the proportion of the gutta-percha to a rubber additive 1 and a rubber additive 2 in a formula. The present invention is characterized by the gutta-percha, the rubber additive 1, the rubber additive 2, an accelerating agent containing sulfur, an antiaging agent, etc. The preparation method comprises the following steps: after raw materials in the formula are blended in a double-roll machine for processing common rubber at a temperature of 50 to 80 DEG C, the raw materials are heated and pressed on a vulcanizing press to prepare the gross rubber for the tires with high abrasion resistance. The present invention has the advantages of natural gutta-percha with wide source, and simple preparation method. The prepared gross rubber has the maximal characteristics of high abrasive resistance, small rolling resistance, low heat rise of dynamic compression, excellent fatigue resistance, good moisture and sliding resistance, and favorable comprehensive balance of tire driving performance; the present invention is ideal gross rubber for developing aircraft tires, etc.
Description
Technical field
The present invention relates to a kind of gross rubber for high wearable tyre and preparation method thereof, is to be the feature raw material with the natural high molecular substance guttapercha, adopts blend sulfurized technological method to prepare gross rubber for high wearable tyre.
Background technology:
High-performance tire, i.e. the tire that has concurrently of low-rolling-resistance, high hauling ability and high-wear resistance is the focus of tire industry research in the world at present.The purpose of research is in order to improve the security of running at high speed, wear resistance and the riding comfort of tire, also is in order to reduce oil consumption, to save the energy.One of key measure that addresses this problem is exactly to develop by the synthetic and processing of new type rubber to satisfy the tire tread material that high-performance tire requires.At present domestic except that natural rubber, low temperature emulsion polymerized styrene butadiene rubber, cis-1,4-polybutadiene rubber three big all-purpose gum kinds, but the problem of above-mentioned sizing material ubiquity wear resistance, rolling resistance, the living heat of dynamic compression, fatigue performance and anti-slippery.Still shortage is applicable to the more elastomeric material that tire, particularly high-performance tire are produced at present, and therefore developing the elastomeric material that can be used in high-performance tire production has become the urgent task that China's rubber industry faces.
Guttapercha is all to be rich in a kind of white rope in skin, leaf, the fruit of gutta-percha tree, be a kind of matter at normal temperatures hard, do not have elastic natural macromolecular material, be known as rigid plastics.Gutta-percha tree is the distinctive commodity trees of China in addition, and natural bark of eucommia forest tree resource is very abundant, and in recent years, under the tissue and call of government, a large amount of gutta-percha trees has been planted in vast mountain area, and the gutta-percha tree cultivated area accounts for more than 90% of global total amount, about 1,000 ten thousand mu.But planting range almost comprised the Shi Yu in NORTHWEST CHINA, southwest, south China, North China and economized wide geographic area, and can be on the hills, the mountain area plantation, discord grain strives ground.For example: the area, Hanzhong just has a large amount of gutta-percha tree strains, if can develop this type of natural gum energetically, not only will make huge contribution for the development of China's national defense industry, aerospace industry, shake off poverty and set out on the road to prosperity in particular for hill farmer and to find a feasible route efficiently, be the development of the West Regions amount of giving a favor.Though, guttapercha has been used to make undersea cable, electrical insulating material, tackiness agent, golf ball etc., and the characteristics of this sizing material maximum are the wear resistance height, and rolling resistance is little simultaneously, dynamic compression is given birth to hot low, and fatigue performance is excellent and anti-slippery is also fine.If but as the preparation gross rubber for high wearable tyre, also existing needs technical problems such as solution and natural rubber, styrene-butadiene rubber(SBR), paracril, cis-1,4-polybutadiene rubber etc. are blend sulfurized.
Summary of the invention
The technical problem that solves
For fear of the deficiencies in the prior art part, the present invention proposes a kind of gross rubber for high wearable tyre and preparation method thereof.Blend sulfurized with gutta-percha and natural rubber, styrene-butadiene rubber(SBR), paracril, cis-1,4-polybutadiene rubber etc., by changing the proportioning of gutta-percha and rubber accelerator 1, rubber accelerator 2 in the prescription, acquisition gross rubber for high wearable tyre.
Technical scheme
Technical characterictic of the present invention is:
Compositing formula is: guttapercha 10-60 part, rubber accelerator 1:10-90 part, rubber accelerator 2:10-90 part, sulfur containing promoter 0.5-4 part, anti-aging agent 1-3 part, zinc oxide 1-2 part, magnesium oxide 0-2 part, sulphur 1-5 part, carbon black 10-40 part, white carbon black 0-30 part, stearic acid 1-10 part.
Described rubber accelerator 1 is natural rubber, chloroprene rubber, isoprene-isobutylene rubber, styrene-butadiene rubber(SBR), ethylene-propylene rubber(EPR), paracril or viton.
Described rubber accelerator 2 is cis-1,4-polybutadiene rubber, silicon rubber, polyurethane rubber or polyacrylic rubber.
Described sulfur containing promoter is 2-mercaptobenzothiazole, dibenzothiazyl disulfide, 2-(morpholine curing)-benzothiazole, N-oxygen diethylene benzothiazole sulphenamide, dithio morpholine or zinc dithiocarbamate.
Described anti-aging agent is N-phenyl-a-naphthylamine, N-Phenyl beta naphthylamine or 1.3-acetaldol-alpha-naphthylamine.
A kind of preparation method of above-mentioned gross rubber for high wearable tyre is characterized in that:
Step 1, with guttapercha, rubber accelerator 1, rubber accelerator 2, sulfur containing promoter, anti-aging agent and other raw material Rubber processing with twin-roll machine in 50-80 ℃ of following blend;
Step 2, on vulcanizing press, heat, curing temperature 140-160 ℃, sulfide stress 120-150MPa.
Beneficial effect
The invention has the beneficial effects as follows: the normal temperature crystal property of gutta-percha excellence makes it to have very high stress at definite elongation and physical strength; Because its molecular backbone chain has the double bond structure feature similar with natural rubber, can carry out vulcanization reaction with Sulfur and make rubber elastomer simultaneously.Gutta-percha and natural rubber, styrene-butadiene rubber(SBR), paracril, cis-1,4-polybutadiene rubber etc. are blend sulfurized, proportioning by gutta-percha and rubber accelerator 1, rubber accelerator 2 in the change prescription, can obtain gross rubber for high wearable tyre, the characteristics of this sizing material maximum are the wear resistance height, rolling resistance is little simultaneously, and dynamic compression is given birth to hot low, and fatigue performance is excellent and anti-slippery is also fine, preferable overall equilbrium with tire running performance is the desirable sizing material of development aircraft tyre etc.
The exploitation of gutta-percha not only can change the situation of the long-term import of China's natural rubber, also can be China new source competent reserve glue kind is provided, and will change the general layout of international natural rubber resource distribution.
