Abstract
The invention relates to a degradable nitrile butadiene rubber sealant which is characterized by comprising the following main components: nitrile butadiene rubber, chlorinated polyethylene, a tackifier, organically chelated metal salt, a filler, a filler modifier, a high-temperature antioxidant, a degradable plasticizer, a photocatalyst, a biodegradable master batch and an environmentally-friendly solvent. The sealant has the advantages that: 1, used waste sealant can be naturally degraded, and by adopting the organically chelated metal salt, the photocatalyst, the biodegradable master batch and the degradable plasticizer, a photodegradation effect and a biodegradation effect are obtained; 2, the nitrile butadiene rubber with low acrylonitrile content is used as a base material, and the chlorinated polyethylene and nano ceramic crystal high-temperature antioxidant are used in coordination with the nitrile butadiene rubber, so that cold resistance and thermal oxidative aging resistance of the sealant are improved; 3, butyl acetate and methyl cyclohexane are used as a mixed solvent, so that environmental protection requirement is met; and 4, the filler modifier has extremely high affinity to the inorganic filler, so that the amount of the filler is increased without affecting sealing property and cost of the sealant is reduced.
Description
Technical field
The present invention relates to the liquid sealant field, but be a kind of paracril class seal gum of functional, broad application temperature range natural degradation specifically.
Background technology
Along with the develop rapidly of automobile industry, the demand that automobile sticks with glue agent increases greatly, and liquid sealant is exactly wherein main a kind of.The rubber that liquid sealant is commonly used has chloroprene rubber, chlorosulfonated polyethylene, paracril etc., because its rate of drying is fast, low price, characteristics such as easy to use, is widely used in fields such as motor car engine, oil pan sealing, mechanical seal.The paracril seal gum is as the most typical, oil-proofness excellent liquid seal gum, in occupation of most of market of liquid sealant.
As everyone knows, common paracril seal gum generally mixes composition by paracril, pigment, filler, auxiliary agent, organic solvent etc. on the market.Because the amorphism of paracril and molecular chain are flexible poor, temperature limit of brittleness is-20 ℃～-10 ℃, main chain contains unsaturated link(age), and the destruction, the hot-air aging resistance that are subject to ozone are not high, and these deficiencies cause the Applicable temperature scope of paracril seal gum to be subjected to certain limitation.
In addition, along with improving constantly of social environment consciousness, low-carbon (LC), environmental protection, the innoxious a kind of expectation that is undoubtedly the numerous common people are accomplished in the processing of solid waste.After using first, the paracril seal gum of traditional technology preparation is difficult to reuse, domestic solid waste reclaim mechanism neither be very perfect, scrap rubber after the dismounting can not get effectively reclaiming and is discarded in the environment, because of its natural degradation difficulty, easily cause environmental pollution as if handling by the mode of landfill, even if handle these scrap rubbers by the mode that tradition is burned, product after the burning, as carbon monoxide, sulfurous gas etc., easily cause secondary pollution, the immense pressure of bringing to Environmental Health can not be ignored.
Therefore, it is imperative to develop a kind of functional, broad application temperature range, low toxic and environment-friendly and liquid sealant that can natural degradation.
Summary of the invention
A kind of degradable paracril seal gum that the object of the present invention is to provide,, the butylacetate of low toxicity little to distinguish the flavor of, methylcyclohexane are mixed solvent, the employing paracril is a base-material, be used chlorinatedpolyethylene, resin, high-temperature antioxidant, organic raw materials such as the metal-salt that closes, degradable type softening agent, photocatalyst, biodegradable master batch of stinging simultaneously, make functional, broad application temperature range, low toxic and environment-friendly and the fast liquid sealant of degradation speed under field conditions (factors).
A kind of degradable paracril of the present invention seal gum is achieved in that by weight ratio and is:
Aforesaid tackifier are at least a in resol, staybelite, the coumarone indene resin;
Aforesaid organic metal-salt that closes of stinging is at least a in iron stearate, calcium stearate, the sodium stearate;
Aforesaid filler is at least a in organic high-purity polynite, light calcium carbonate, the aluminium triphosphate;
Aforesaid filling modifier is a JL-G02 type filling modifier;
Aforesaid high-temperature antioxidant is a nanometer Tao Jing high-temperature antioxidant;
Aforesaid degradable type softening agent is an epoxy soybean oil;
Aforesaid photocatalyst is at least a in dioxide photocatalyst titanium dispersion liquid, the metalloporphyrin;
Aforesaid biodegradable master batch is the JHSM biodegradable master batch;
Aforesaid environmentally friendly solvent is at least a in butylacetate, the methylcyclohexane.
The preparation method of a kind of degradable paracril of the present invention seal gum is as follows:
1. by weight ratio, respectively paracril and chlorinatedpolyethylene are plasticated, the rubber that to plasticate, organic metal-salt, tackifier, filler, filling modifier, high-temperature antioxidant, degradable type softening agent, photocatalyst, biodegradable master batch of closing of stinging are mixing evenly then, and cooling is chopped into mixing micelle.
2. by weight ratio, environmentally friendly solvent is added reactor, drop into the mixing micelle of above-mentioned preparation method's 1 gained under whipped state, it is even to be stirred to glue, gets product.
On the present invention's a kind of degradable paracril seal gum and the market there be the correlated advantage of like product:
1. but the scrap rubber natural degradation after using adopts organic chelated metal-salt, photocatalyst, biodegradable master batch and degradable type softening agent, possesses the dual degradation effect of light or organisms, and degradation speed is fast under extraneous natural condition;
2. broad application temperature range, adopting the paracril of low acrylonitrile content is base-material, is used chlorinatedpolyethylene and nanometer Tao Jing high-temperature antioxidant, has improved the winter hardiness and the hot-air aging resistance of seal gum;
3. smell is little, and toxicity is low, adopts butylacetate, methylcyclohexane as mixed solvent, compliance with environmental protection requirements;
4. the filling modifier of Shi Yonging has extremely strong affinity to mineral filler, has increased the consumption of filler under the condition that does not influence sealing property, makes seal gum amount of solid content height, cost low.
