Abstract
The invention discloses a hot-formed automobile interior panel and a manufacture method thereof. The hot-formed automobile interior panel comprises a hemp felt layer. Epoxy resin layers are disposed on both sides of the hemp felt layer. The automobile interior panel comprises, in mass percentage, 60-70% of the hemp felt layer and 40-30% of the epoxy resin layers. The manufacture method includes steps: drying pure hemp felt material to make water content of the hemp felt material to be 6-12%; spraying epoxy resin powder evenly on both sides of the hemp felt material; putting the hemp felt material in a forming die in a temperature of 105-115 DEG C; implementing die sinking for once and die assembly; and obtaining finished product by die sinking. By using pure hemp felt and resin to replace PP (plastic particles) and PP plus hemp felt material, tensile property of the finished product is enhanced, weight is reduced, and environment protection demands are met.
Description
Technical field
The present invention relates to a kind of automotive trim panel and working method thereof, particularly relate to hot-forming automotive trim panel and the working method thereof of a kind of pure numb felt spray epoxy.
Background technology
Existing automobile door internal decoration plate upper frame all is directly to adopt PP injection mo(u)lding or the hot-forming production technology of PP fiber crops felt.PP injection mo(u)lding production process is under high temperature, high pressure, molten plastic to be injected the die cavity process of cooling forming then; The Shooting Technique process is simple; Through control baking temperature, injection temperature speed and pressure, dwell time and parameters such as pressure, mold temperature, reasonably relate to mould, select correct injection machine can guarantee the automotive upholstery quality of stability.Though PP injection molding process technology maturation, manufactured parts weight lays particular stress on, the tensile strength index is not outstanding.And the hot-forming trim panel of PP fiber crops felt has overcome the big shortcoming of PP injection moulding trim panel weight, and the tensile strength index does not have big lifting.For lightweight, environmental protection requirement that present auto trade proposes, these technologies can't satisfy the high requirement of customer more and more.
Summary of the invention
An object of the present invention is to provide a kind of hot-forming automotive trim panel, more original PP injection moulding of automotive trim board finished product or the hot-forming product weight that obtains of PP fiber crops felt are light, and intensity is high, compliance with environmental protection requirements.
Another object of the present invention provides a kind of working method of hot-forming automotive trim panel.
Technical scheme of the present invention is such:
A kind of hot-forming automotive trim panel; Comprise numb carpet veneer, it is characterized in that said numb carpet veneer tow sides are provided with epoxy resin layer; It is 60～70% that said numb carpet veneer accounts for the automotive trim panel percent by weight, and it is 40～30% that said epoxy resin layer accounts for the automotive trim panel percent by weight.
A kind of hot-forming working method of automotive trim panel is characterized in that may further comprise the steps:
(A) pure numb felt material is dried processing, make pure numb felt aqueous ingredients reach 6～12%;
(B) the two-sided even sprinkling epoxy powder of dry pure numb felt that step (A) is obtained makes pure numb felt account for automotive trim panel mass ratio 60～70%, and epoxy powder accounts for automotive trim panel mass ratio 40～30%;
(C) the pure numb felt of double-face spray painting epoxy resin being put into temperature is 105～115 ℃ of forming moulds, die sinking 5～10s, matched moulds pressurize 40～50s again behind mould matched moulds reaction 8～12s;
(D) die sinking obtains finished product.
The advantage of technical scheme provided by the present invention is, adopts pure numb felt to add resin substituted for plastic particle PP and PP adds numb felt material, improved the fabricated part tensile property, alleviated weight, compliance with environmental protection requirements simultaneously.Control moisture in the fiber crops felt dry run, make numb felt keep certain intensity, not yielding during the spray epoxy powder, the compression molding stage is difficult for taking place lamination; The control of forming mould heating-up temperature makes epoxy resin cure be beneficial to operation rapidly again; Die sinking 5～10s in the matched moulds reaction discharges redundant moisture, helps moulding, reduces the product lamination.
The specific embodiment
Below in conjunction with embodiment the present invention is described further.
