Description

A kind of environment-friendly type automobile inner decoration composite material and preparation method
Technical field
The invention belongs to technical field of polymer materials, are related to a kind of automobile interior decoration composite material and preparation method, especially It is related to a kind of environment-friendly type automobile inner decoration composite material and preparation method.
Background technique
Instrument board is the important component of automobile interior decoration.In recent years, with the continuous progress of technology, more operating works It can be integrated into instrument board.Obviously, in order to ensure the various instrument and part that are supported can run at high speed and vibrate Worked normally under state, instrument board must have enough rigidity, and occur to reduce external force when accident to just, copilot Impact also requires instrument board to have good energy absorption capacity.Meanwhile for comfortable and aesthetic requirement, the feel of instrument board, skin Line, color and tone etc. are also increasingly subject to the attention of people.
In short, instrument board collects safety, functionality, comfort and dicoration in one as a kind of unique inner-decoration component Body, the quality of these performances have become one of the major criterion for judging vehicle grade.Generally, instrument provisioned in different vehicles Plate grade is entirely different.According to the configuration requirement of vehicle, suitable instrument board production technology may be selected, reduce life to reach Produce the purpose of cost.
Decorative sheet in middle of vehicle door generallys use three-decker: epidermis uses PVC or PVC+ABS material;Buffer layer uses PUR Foamed material;Skeleton is using materials such as MODIFIED PP, ABS.Traditional decorative sheet in middle of vehicle door has the following problems:
(1) decorative sheet in middle of vehicle door is difficult to recycle.Decorative sheet in middle of vehicle door has three-decker, and the material category of each layer is different It causes, thermal characteristics is also inconsistent.Therefore, it when decorative sheet in middle of vehicle door recycles, needs first to split epidermis, buffer layer and skeleton, The recycling of each layer is carried out again.The recycling of traditional decorative sheet in middle of vehicle door is extremely complex, and process is more, and can not recycle completely.
(2) traditional decorative sheet in middle of vehicle door epidermis uses PVC or PVC+ABS material.PVC or PVC+ABS material is in addition to packet Basic resin is included, addition plasticizer, stabilizer etc. are also needed.PVC or PVC+ABS epidermis thermal stability is poor, will cause not after heated With the degradation of degree, small-molecule substance is released, volatility is high, causes in-vehicle air pollution.
The trim panels material such as traditional arrangements for automotive doors, instrument board, which generally passes through, repeatedly to be formed, complex process, equipment valuableness, High production cost.Superficial layer, foaming layer and casing play are bonded usually using organic glue or other adhesive, with spraying Or rolling gluing or other processing methods, long-time service release noxious material are harmful to the human body, not environmentally.Product surface lines, Color consistency is poor, and grain pattern is limited, and color is not easy to replace.During processing not environmentally, there are pollution, Fei Rengong.
Therefore, it is expected to obtain one kind in this field may be easy to process, and adhesive strength is high, and wearability is excellent, have high Tearing strength and dimensional stability are not easy to peel off, and comfortable feel is good, environmental protection, and specious automotive interior material.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the present invention is to provide a kind of automobile interior decoration composite material and its preparation sides Method is especially to provide a kind of environment-friendly type automobile inner decoration composite material and preparation method.
