Abstract
The present invention provides a kind of surface layer for automobile interiors and preparation method thereof, the surface layer for automobile interiors includes a bottom and an internal decorative layer, the bottom is connect with automotive trim panel, the interior trim is placed on the bottom, the internal decorative layer has a nonwoven layer and a carbon cloth adsorption layer, in air, the carbon cloth adsorption layer is arranged between the nonwoven layer and the bottom for the nonwoven layer exposure.The advantage of the invention is that, carbon cloth adsorption layer is made in existing carbon dust by the preparation method of present invention surface layer for automobile interiors, overcome the defect using carbon powder particle as the structure of absorption peculiar smell, and environmentally friendly, unharmful substance volatilization, while there is excellent absorption peculiar smell performance and purification air performance.
Description
Technical field
The present invention relates to field of automobile decoration more particularly to a kind of surface layer for automobile interiors and preparation method thereof.
Background technique
With the different raising of the day of people's living standard, automobile is being entered step by step in each of us life,
We are likely to contacting and using automobile daily.Concern along with people to own bodies health, the matter of automobile interior decoration
Amount requirement, environmental protection, comfort requirement etc. more obtain the attention of majority.At present automobile production interior material, seat liner leather sheath,
Bottom plate interlayer etc. is all mainly made of non-weaving cloth composite materials such as polyurethane, polyvinyl chloride, and these polyurethane are compound
Manufactured material more or less all uses solvent type production system in the fabrication process.The use of organic solvent, not only gives birth to
Environment is polluted in production, and seriously compromises people's health.For example, in 1, production process largely using solvent substance or
The volatile substances such as person's glue or odorous chemicals such as ammonium hydroxide；2. material itself volatilizes a large amount of gas when production process high temperature
Body damages the health of people；3. being influenced in actual use by environment temperature, the long-term of humidity, material decomposes slow
The slow vaporization sustainable time for 3~6 months, causes interior long-time smell very heavy, causes to the use of people very big
Influence.With the enhancing of people's environmental consciousness and the gradual perfection of environmentally friendly laws and regulations, pollution-free, unharmful substance volatilization is closed
Become the emphasis that each enterprise falls over each other research at material technology.
Therefore, a kind of environmentally friendly, unharmful substance volatilization is manufactured, while there is excellent absorption peculiar smell performance, net
