Description

A kind of EPDM foam is except aldehyde ordor removing complex biological enzyme solutions and preparation method thereof
Technical field
The present invention relates to a kind of EPDM foams except aldehyde ordor removing complex biological enzyme solutions and preparation method thereof, belongs to environmental organism Technical field.
Background technique
EPDM foam, is also ethylene propylene diene rubber foaming materials.Ethylene propylene diene rubber (EPDM) is ethylene, propylene and non- The terpolymer of conjugated diene.EPDM foam is exactly to use ethylene propylene diene rubber for primary raw material, through mixing, mold hair Bubble, deburring, cut open piece and etc. EPDM foamed material is made.
EPDM foam have excellent resistance to weather, resistance to ozone, corrosion-resistant, heat-resisting, stability, have good heat insulating ability, every The characteristics such as hot, buffering, shockproof, sound-absorbing, sound insulation, sealing, fire-retardant.Based on above-mentioned characteristic, EPDM foam is widely used in automobile Between components, as filling, dust-proof, shockproof, sealing, waterproof action.
In EPDM and EPDM foam production process, vulcanizing agent and a lot of other auxiliary agents, meeting after material generates will use There are some auxiliary agents to remain, remaining auxiliary agent can generate unpleasant peculiar smell, can also generate formaldehyde, ammonia, TVOC (Total Volatile The abbreviation of Organic Compounds, volatile organic matter) etc. polluted gas.When these materials be applied to automobile on, not in time It removes these harmful substances, pollutes in-vehicle air environment, the adverse reactions such as dizziness, nausea can be brought to driver and a variety of exhale Inhale tract disease.
The taste removal directly against EPDM foam still belongs to blank at present.Conventional method is only directed to the taste removal side of EPDM rubber Method generally selects tasteless vulcanizing agent and eliminating smell agent to will affect the performance of EPDM, and then influences the performance of EPDM foam.And it can not Remove formaldehyde, ammonia and TVOC.
Application No. is 201410480570.5 " a kind of formulas of environment-friendly tasteless ethylene propylene diene rubber ", application No. is 201410067778.4 " ethylene propylene diene rubber environmental protection sebific duct and its manufacturing methods ", application number 201610534069.1 are " a kind of resistance to The EPT rubber composition of high-temperature oil resistance and low smell " refer to using eliminating smell agent, it, cannot although peculiar smell can be reduced Fundamentally remove the pernicious gases such as formaldehyde, ammonia and TVOC.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of EPDM foams to remove aldehyde ordor removing compositional biological enzyme Solution and preparation method thereof can simply, efficiently remove EPDM residual auxiliary agent and volatile harmful gases, thoroughly removal EPDM The had sharp aroma of foam.
The technical scheme adopted by the invention is that: a kind of EPDM foam removes aldehyde ordor removing complex biological enzyme solutions, the compounding The weight percent composition of the formula of biological enzyme solutions are as follows: biological enzyme 20~30%, plant extraction liquid 20~30%, carboxymethyl shell Glycan 0.1~0.5%, glutathione 0.01~0.1%, pH buffer 1-5%, surplus are deionized water.Preferably, described The weight percent composition of biological enzyme proportion are as follows: laccase 5~10%, pectase 5~10%, formaldehyde dehydrogenase 1~5%, formic acid Dehydrogenase 1~5%, superoxide dismutase 0.5~1%, arene oxidizing object hydrolase 0.5~1%, lysozyme 1~2% are remaining Amount is deionized water.Preferably, the pH buffer is one of Tris-HCl, phosphate buffer, acetate buffer.
Preferably, the EPDM foam is aperture, half aperture and closed pore foam.
The invention also discloses a kind of EPDM foams to remove aldehyde ordor removing compositional biological enzyme solution manufacturing method, by the following method Preparation:
S1: by laccase, pectase, lysozyme, formaldehyde dehydrogenase, hydrogenlyase, superoxide dismutase, arene oxidizing Object hydrolase is soluble in water to be made biological enzyme solutions；S2: carboxymethyl chitosan is soluble in water, PH buffer, gluathione is added Peptide, plant extraction liquid；S3: being added to biology enzyme solutions in step S2 solution, be sufficiently stirred, and obtains the EPDM foam except aldehyde Ordor removing complex biological enzyme solutions.
With prior art ratio, the present invention is had the beneficial effect that: the present invention uses biological enzyme, belongs to biocatalyst, Only to its effect of specific substrate, the performance of material is not influenced.Cellulase treatment method has catalysis efficiency height, reaction condition temperature It is exceedingly fast with easy to operate, low for equipment requirements, processing speed, do not cause secondary pollution.EPDM foam of the invention removes aldehyde ordor removing Complex biological enzyme solutions not only except aldehyde ordor removing effect is good, but also are readily produced.
Detailed description of the invention
Fig. 1 is the process flow diagram of EPDM foam.
Specific embodiment
With reference to the accompanying drawing, technical solution of the present invention is described in further detail, but does not constitute and of the invention is appointed What is limited.
