Description
Technical Field
The utility model relates to a glued membrane technical field, concretely relates to fire-retardant preimpregnation material structure of integrated autohension.
Background
The functional and light material is the subject of the current novel material, and the polypropylene (PP) plastic with lower specific gravity and the honeycomb structure bring more excellent application performance and have wide application prospect.
The PP honeycomb plate is a plate made by two thin panels firmly adhered to two surfaces of a layer of thick honeycomb core material, and is also called a honeycomb sandwich structure. The structure has the advantages of light weight, high rigidity, no toxicity, environmental protection, shock absorption, cold resistance, sound insulation, heat preservation, moisture prevention, heat insulation and the like, and is widely applied to the inner decoration parts of trunk cover plates, trunk partition plates, trunk carpet base plates, side wall decorative plates, ceilings and the like, engine turnover boxes and the like of medium and high-grade passenger vehicles. For example, the turnover box for automobile parts is currently produced mainly in germany and japan, and although domestic enterprises have started, they have not been marketed for two years.
One of the technical difficulties in the preparation of PP cellular boards is compounding. The traditional glue can be compounded, but on one hand, the glue is not in accordance with the environmental protection concept; on one hand, most glue is a curing system, so that low-temperature brittleness is serious, and the performance cannot be guaranteed. While hot melt adhesive type products currently do not have an adhesive suitable for a five-layer composite process.
Disclosure of Invention
The utility model discloses mainly solve and have structural stability difference, easily fire and the short not enough of life among the prior art, provide the fire-retardant preimpregnation material structure of integrated autohension, it has simple structure, stable good, fire-retardant and long service life's characteristics. The problem of prepreg need a large amount of time adopt permanent manual work shop to paste is solved.
The above technical problem of the present invention can be solved by the following technical solutions:
the utility model provides an integrated fire-retardant preimpregnation material structure of autohension, includes the core, the core outside be equipped with the core paste the formula mutually and be connected fixed fire-retardant preimpregnation material subassembly. The flame-retardant prepreg assembly comprises a flame-retardant resin layer, and an adhesive resin layer is arranged between the flame-retardant resin layer and a core material. The core material is a material structure such as honeycomb or foam.
Preferably, a heat insulation support layer is arranged between the flame-retardant resin layer and the bonding resin layer.
Preferably, the heat insulation support layer comprises a plurality of longitudinal coarse glass fibers, and transverse coarse glass fibers which are interwoven with the longitudinal coarse glass fibers in a crisscross manner are arranged on the longitudinal coarse glass fibers.
Preferably, a longitudinal thin glass fiber is arranged between two adjacent longitudinal thick glass fibers and crossly interlaced with the transverse thick glass fiber, and a transverse thin glass fiber is arranged between two adjacent transverse thick glass fibers and crossly interlaced with the longitudinal thick glass fiber and the longitudinal thin glass fiber.
Preferably, the adhesive resin layer includes adhesive resin fibers having a honeycomb woven structure.
The utility model discloses can reach following effect:
the utility model provides a fire-retardant preimpregnation material structure of integrated autohension compares with prior art, has simple structure, stable good, fire-retardant and long service life's characteristics. The problem of prepreg need a large amount of time adopt permanent manual work shop to paste is solved.
