Description
Technical field
The present invention relates to auto parts machinery technical field, relate in particular to the chlorinated polyethylene rubber composition of easily degrading for automobile.
Background technology
China is world rubber industry big country, and a year consumption glue amount is the first in the world in continuous 8 years, and 2009,588 tons, consumption glue, accounted for 26.5% of whole world consumption glue amount. Along with Domestic Automotive Industry suspenseful breakthrough in 2010 is produced 1,600 ten thousand, within 2010, China's rubber consumption still keeps the first in the world, along with the rise of global low-carbon economy, green manufacturing has become one of strategy and policy of China's rubber industry sustainable development, for strengthening industry restructuring, the raw material of greatly developing safety, energy-saving and environmental protection are bases of green manufacturing. And at present Chinese rubber industrial materials prices sharp rises, particularly natural rubber is from 2009 to 2011 more than rise in price 1/3rd. Face resource disparities between supply and demand outstanding, the high-order severe form increasing of price, will certainly affect the stable development of rubber industry, therefore,, under this severe situation, rubber industry is all in positive industry restructuring, change growth pattern, energy-saving and cost-reducing energetically, strengthen Enterprise Innovation Capability, improve quality, benefit and the enterprise competitiveness on market. Rubber is with plastics and fiber and be called three large synthetic materials, and wherein natural rubber is unique have height retractility and fabulous flexible macromolecular material, and first the maximum feature of rubber is that springform skill amount is very little, and percentage elongation is very high. Elasticity is large, and degree of stretching is high surely, and tear resistance and electrical insulating property are good, and wearability and drought tolerance are good, and processability is good, is easy to same other materials bonding, is better than most synthetic rubber aspect combination property. Shortcoming is that oxytolerant and ozone resistance are poor, easily aged deterioration; Oil resistant and solvent resistance are bad, and cold resistance is good, and goods serviceability temperature scope is at-60 DEG C to 180 DEG C.
Rubber can carry out with multiple material and use, blend, compound, carries out thus modification, to obtain good combination property. Also have chlorinated polyethylene rubber (CM or CPE) be polyethylene make by chlorine substitution reaction there is flexible polymer, its performance and chlorine vulcanized polyethylene rubber approach, be characterized in good fluidity, easily processing, have good resistance to weather, ozone resistance and corona resistance, heat-resisting, acid and alkali-resistance, oil resistivity are good; Shortcoming is that compression is larger, and electrical insulating property is lower, approximately-20 DEG C to+120 DEG C of serviceability temperature scopes, good toughness. There is good compatibility with other macromolecular materials, and can reach good result of use.
It is because it has outstanding heat oxygen aging resistance, ozone aging, acid and alkali-resistance that haloflex has outstanding advantage, its oil resistance is outstanding, wherein resistance to ASTM1 oil, ASTM2 oiliness can be splendid, can be suitable with NBR, resistance to No. ASTM3 oily function admirable, is better than CR, suitable with CSM, in haloflex, contain chlorine element, there is splendid fire resistance, and have the anti-characteristic of dripping of burning. It is in Sb system fire retardant, chlorinated paraffin wax, AI (OH)3The suitable ratio of three coordinates can obtain fire resistance fire proofing good, with low cost, and the good processability of haloflex, Mooney viscosity (ML1211+4) has the multiple trade mark can supply rotation between 50-100, can replace a part of raw material in robber materials to use, and its performance even similar than some in raw-material performance more outstanding, price is also cheaply many than the raw material in similar, therefore how to apply it in rubber and replace a part of raw material, the cost performance that improves elastomeric material is vital.
