Abstract
The invention discloses an organic silicon sealant for a body chassis. The sealant comprises, by weight, 15-30 parts of beta-cyclodextrin grafted polyacrylamide, 10-20 parts of poly(p-dioxanone), 45-55 parts of lignin polyurethane, 5-15 parts of a modifier, 5-15 parts of chitosan quaternary ammonium salt, 25-35 parts of polyhydroxyalkanoate, 30-40 parts of high impact polystyrene, 7-17 parts of a rice hull extract and 6-16 parts of an eucommia extract. Through the above mode, the sealant of the invention has high strength and good compressive property, and is used to effectively enhance safety performance of automobiles.
Description
Technical field
The present invention relates to sealing agent field, particularly relate to a kind of chassis of vehicle body organic silicon sealant.
Background technology
Organic silicon sealant is the silicon rubber macromolecular material of a class excellent performance, there is good high-and low-temperature resistance, excellent electrical insulating property, good resistance to deterioration, the advantages such as outstanding surfactivity, and there is the features such as nontoxic, physiological inertia, many industries particularly electric and aerospace industry be widely applied.Because organosilicon material exists many weakness, such as intensity is low, inflammable does not possess anti-flaming function etc., limits its application.Along with China's modern industry, more and more harsher to material performance requirement.Current safety of China production situation is more and more serious, improves constantly, carries out modification to organic silicon sealant, improve constantly its over-all properties, particularly improve its flame retardant properties to the safety requirements of material, significant, also has wide market outlook.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of chassis of vehicle body organic silicon sealant, and intensity is high, and compressive property is good, effectively improves the safety performance of automobile.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of chassis of vehicle body organic silicon sealant, sealing agent comprises: grafted by beta cyclodextrin polyacrylamide, PPDO, xylogen type polyurethane, properties-correcting agent, chitosan quaternary ammonium salt, polyhydroxyalkanoate, high-impact polystyrene, rice shell extract, Cortex Eucommiae extract, the weight proportion of its each component is: grafted by beta cyclodextrin polyacrylamide 15 ~ 30 parts, PPDO 10 ~ 20 parts, xylogen type polyurethane 45 ~ 55 parts, properties-correcting agent 5 ~ 15 parts, chitosan quaternary ammonium salt 5 ~ 15 parts, polyhydroxyalkanoate 25 ~ 35 parts, high-impact polystyrene 30 ~ 40 parts, rice shell extract 7 ~ 17 parts, Cortex Eucommiae extract 6 ~ 16 parts.
In a preferred embodiment of the present invention, described properties-correcting agent is 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride.
In a preferred embodiment of the present invention, described rice shell extract is ceramide.
In a preferred embodiment of the present invention, described Cortex Eucommiae extract is chlorogenic acid.
