Abstract
The utility model relates to an environment-friendly decorative sheet in the middle of a vehicle door and aims to provide an environment-friendly decorative sheet in the middle of the vehicle door, which can be conveniently recycled and can reduce pollution to the environment in a vehicle. The environment-friendly decorative sheet has a three-layer composite structure and comprises a surface layer, a buffer layer and a framework. The surface layer is made of TPO (thermoplastic polyolefin) material. The buffer layer is made of EPP (expanded polypropylene) expanded material. The framework is made of modified PP (propene polymer) material. The similar polypropylene thermoplastic materials are adopted to manufacture the composite decorative sheet for the vehicle door through hot-pressing molding. Therefore, the environment-friendly decorative sheet is beneficial for being recycled and can reduce the continuous pollution to the environment in the vehicle.
Description
Technical field
The utility model relates to automobile manufacturing field, and in particular, the utility model is the environment-friendly type car door middle part decorative panel that helps the recycling of door trim plate about a kind of.
Background technology
Car door middle part decorative panel generally adopts three-decker: epidermis adopts PVC or PVC+ABS material; Cushion adopts the PUR expanded material; Skeleton adopts materials such as MODIFIED PP, ABS.There is following problem in tradition car door middle part decorative panel:
(1) car door middle part decorative panel is difficult to reclaim.Car door middle part decorative panel has three-decker, and the material category of each layer is inconsistent, and thermal characteristics is also inconsistent.When therefore car door middle part decorative panel reclaims, need earlier epidermis, cushion and skeleton to be split, carry out the recovery of each layer again.Simultaneously, polyurethane foam heating can't fusion, is used for parts such as sound-heat insulated cushion after can only shredding.The recovery of tradition car door middle part decorative panel is very complicated, and operation is many, and can't reclaim fully.
(2) traditional car door middle part decorative panel epidermis employing PVC or PVC+ABS material.PVC or PVC+ABS material also need add plasticizer, stabilizing agent etc. except comprising basic resin.PVC or PVC+ABS epidermis poor heat stability will cause degraded in various degree after being heated, discharge small-molecule substance, and the volatility height causes in-vehicle air pollution.
Patent Office of the People's Republic of China discloses a CN1150774A document on May 28th, 1997, name is called process for producing multi-layer molded articles, the multi-layer molded articles of disclosed door trim material etc., be after being squeezed into sheet by the epidermis molten resin layer that forms soft thin surface layer material, the base material molten resin layer that forms the middle molten resin layer in soft intermediate layer of foaming and form base material by extruder die, to press base material molten resin layer and below mould state of contact feed.The epidermis molten resin layer of compression forming is a thermoplastic elastomer (TPE).Middle molten resin layer be contain blowing agent, ethene and have the ethene copolymer of free-radical polymerised acid anhydrides copolymerization at least.The base material molten resin layer is an olefine kind resin.The thermoplastic elastomer (TPE) of epidermis molten resin layer should be olefin hydrocarbons thermoplasticity elastic body and/or styrene analog thermoplastic elastomer.The car door composite that this method provided is exactly the material extrusion modling by variety classes, different thermal characteristics, and shortcoming is to be not easy to recycle, and environment inside car is produced certain pollution.
Summary of the invention
The utility model is not easy to recycle and environment inside car is produced certain pollution problems for solving the composite that exists in the prior art, provides a kind of can conveniently the recycling also can reduce the environment-friendly type car door middle part decorative panel that generation is polluted to environment inside car.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of environment-friendly type car door of the present utility model middle part decorative panel, have three-layer composite structure, comprise top layer, cushion, skeleton, the top layer is the TPO material, cushion is the EPP expanded material, and skeleton is the MODIFIED PP material.TPO material, EPP expanded material, MODIFIED PP material all belong to the PP type thermoplastic; During recovery, only need decorative panel is pulverized, be used for other processing industries as filler behind the heating and melting, compare with the recovery of traditional car door middle part decorative panel, technology is very simple, effectively reduces the energy consumption in the removal process, has improved the rate of recovery of car door middle part decorative panel simultaneously; Top layer material therefor TPO material is compared with PVC or PVC+ABS epidermis, has good emission characteristics, after placing in short-term, promptly reaches stable state, thereby has reduced the chronic pollution to environment inside car.
As preferably, TPO material, EPP expanded material, MODIFIED PP material are by the hot-forming integral body that is connected to.Have certain intensity by the hot-forming composite decorating board that makes, reduce additive simultaneously and use, reduce pollution environment inside car.
As preferably, the thickness of TPO material is 0.5-1.5mm, and the thickness of EPP expanded material is 1-3mm, and the thickness of MODIFIED PP material is 2.5-5mm.The thickness of layers of material is selected according to being intensity, pliability and cost, and when layers of material was in this scope, the door trim plate had reliable intensity, and the top layer has good pliability, and cost is at zone of reasonableness.
Further, the thickness of TPO material is 1mm, and the thickness of EPP expanded material is 2mm, and the thickness of MODIFIED PP material is 4mm.When making by this thickness, layers of material has optimum properties, promptly reliable intensity, good pliability, economic cost.
The beneficial effects of the utility model are: adopt the hot-forming car door composite decorating board of making of similar PP type thermoplastic, help recycling, and can reduce the chronic pollution to environment inside car.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model environment-friendly type car door middle part decorative panel.
Among the figure: 1. TPO material, 2. EPP expanded material, 3. MODIFIED PP material.
The specific embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings the technical solution of the utility model is described in further detail.
Embodiment:
A kind of environment-friendly type car door middle part decorative panel of present embodiment referring to Fig. 1, has three-layer composite structure, and the top layer is a TPO material 1, and cushion is an EPP expanded material 2, and skeleton is a MODIFIED PP material 3, all belongs to the PP type thermoplastic; The thickness of TPO material is 1mm, and the thickness of EPP expanded material 2 is 2mm, and the thickness of MODIFIED PP material 3 is 4mm.
