Preferably, the weight of described rubber and softening agent is 100/10 ~ 100/15.
Preferably, described softening agent is dioctyl phthalate (DOP).
Preferably, described colored high wear-resistant rubber dam is made up of the material of following weight part: rubber 100 parts, 12 parts, softening agent, strengthening agent 50 parts, pigment 6 parts, titanium dioxide 10 parts, 2 parts, anti-aging agent, anti-wear agent 3 parts, promoting agent 5 parts and vulcanizing agent 4 parts.
Be more preferably, described colored high wear-resistant rubber dam is made up of the material of following weight part: chlorosulfonated polyethylene rubber 90 parts, natural rubber 10 parts, o-phthalic acid dibutyl ester 12 parts, white carbon black 40 parts, nano-calcium carbonate 10 parts, pigment 6 parts, titanium dioxide 10 parts, 2 parts, anti-aging agent, anti-wear agent 3 parts, promoting agent 5 parts and vulcanizing agent 4 parts.
Preferably, described chlorosulfonated polyethylene rubber is CSM-40 type chlorosulfonated polyethylene rubber.
Advantageous Effects of the present invention is:
After testing, its Akron abrasion loss of the colored high wear-resistant rubber dam of the present invention can reach 0.10cm
3/ 1.61km, wear resistance is better, and the physical and mechanical properties such as its resistance to ozone, tensile strength and tensile yield also all meets industry standard, can meet the requirement to colorful rubber dam abrasion resistance properties and physical and mechanical properties of under severe rugged environment water conservancy industry.
Embodiment
Generally, the glue kind that molecular chain kindliness is good, elasticity is high, second-order transition temperature is lower, wear resistant is high, as cis-butadiene cement etc., and in the present invention, contriver selects chlorosulfonated polyethylene rubber, because its tensile strength is high, ozone resistance is excellent, and particularly fade resistant performance is given prominence to, possess again higher abrasion resistance, be the elite clone preparing colored high wear-resistant rubber dam simultaneously.For the physical and mechanical properties such as binding property of the wear resistance and sizing material and rubber dam framework material that consider colorful rubber dam, contriver also by chlorosulfonated polyethylene rubber and natural rubber according to a certain ratio and use, and object, one is reduce temperature limit of brittleness when consistency is good; Two is the processing characteristicies improving sizing material, also can improve the physical and mechanical properties on colorful rubber dam in addition.
By test, rubber proportioning is selected:
1.1 main raw material(s)
Chlorosulfonated polyethylene CSM-40 type rubber, natural rubber, o-phthalic acid dibutyl ester, other Synergist S-421 95 (white carbon black, nano-calcium carbonate, pigment, titanium dioxide, anti-aging agent, anti-wear agent, promoting agent and vulcanizing agent), is more than commercially available starting material.As chlorosulfonated polyethylene rubber CSM-40, Jilin Petrochemical Company of China Petrochemical Industry; Softening agent, Shandong, Shandong softening agent limited-liability company; White carbon black (precipitator method), Shandong Xiang Run novel material company limited; Nano-calcium carbonate, Zibo white clouds nanosecond science and technology company limited; Titanium dioxide (rutile-type), Nanjing titanium white Chemical Co., Ltd., in this formula, titanium dioxide is pigment and inorganic ultraviolet-resistant absorbent; Antioxidant MB (2-mercaptobenzothiazole), Hebi City Rong Xin auxiliary agent company limited; Anti-wear agent DC-Z-B (mixture such as vinyl silanes), Wuxi City Dong Cai Science and Technology Ltd. etc.
1.2 testing installation
Banbury mixer, vulcanizing press, tension testing machine, resistance to ozonograph, Akron abrasion machine, climatic chamber.
1.3 performance test
Properties all performs according to existing national rubber industry testing standard.
Change rubber composition proportion, other materials consumption is constant, and rubber proportioning selection result sees the following form 1.
Table 1
Data analysis in his-and-hers watches 1 finds, rubber composition proportion its abrasion performance different difference is larger, and contriver selects the good rubber paralled system of wear resistance, be especially 90/10 (weight part) with chlorosulfonated polyethylene rubber/natural rubber is preferred.
The wear resistance of rubber mainly strengthens by supporting materials such as carbon blacks.Colorful rubber dam can only add the wear resisting property that light supporting material is used for improving rubber dam due to the restriction of color.The light strengthening agent index affecting wear resisting property mainly contains particle diameter, tensio-active agent and dispersiveness.In the starting material on the colored high wear-resistant rubber dam of preparation, the active carbon white of the preferred silane coupling agent process of contriver and nm-class active calcium carbonate are as the strengthening agent of chlorosulfonated polyethylene rubber, and the two has reinforcing and dispersed preferably to chlorosulfonated polyethylene rubber.
Test by following weight: rubber (chlorosulfonated polyethylene rubber CSM-40/ natural rubber is 90/10) 100 parts, 12 parts, softening agent, white carbon black variable, nano-calcium carbonate variable, titanium dioxide 10 parts, pigment 6 parts, 2 parts, anti-aging agent, anti-wear agent 3 parts, promoting agent 5 parts and vulcanizing agent 4 parts.Wherein pigment, anti-aging agent, anti-wear agent, promoting agent and vulcanizing agent can carry out routine according to the experience of those skilled in the art and select, and commercially obtain.Strengthening agent is preferably the composition of white carbon black and nano-calcium carbonate, and change weight therebetween, all the other raw material usage are constant, and concrete test-results is as following table 2.
Table 2
Data analysis in his-and-hers watches 2 can be found out, the rubber dam abrasion performance obtained by above formula is all lower than 0.8cm
3/ 1.61km, and the physical and mechanical properties such as tensile strength and tensile yield also all meets industry standard.Contriver considers wear resistance and the physical and mechanical properties of rubber dam, and preferred white carbon black/nano-calcium carbonate ca proportion is the paralled system of 40/10 (weight part).
