The enhanced low-density pre-foamed plastic board has the characteristics of good mechanical and physical properties, light weight, low cost, applicability of reutilization, and the like. The products formed by multiple layers of the boards can be used for manufacturing automobile ceilings, air directors and other parts.
Description
Technical field
The utility model relates to a kind of non-natural continuous filament yarn fabric and strengthen low-density prefoam plastic plate, be specifically related to a kind of reinforced plastics sheet material that strengthens composite plastic sheet material through the compound preparation of multilayer thermoplastic.Belong to composite technology.
Background technology
Goods such as the high-strength nylon of present prior art, PC, polyformaldehyde, polysulfones, polyethers; Glass fiber reinforced plastics product and various plastic alloy engineering goods and sheet material thereof; In all trades and professions such as vehicular traffics such as electronics, machinery, building, automobile and daily living article field, widely use, and obtained a feather in one's cap.
Yet, because polypropylene, polyethylene, polyurethane and thermoplastic commonly used such as polystyrene and polyvinyl chloride exist common deficiencies such as poor rigidity, low, the bent clothes pressure-bearing of bearing capacity difference.Its mechanical and physical performance and chemical property also can not satisfy the requirement of used sheet materials such as vehicular traffic, military engineering such as automobile far away, thereby have restricted the light-weighted development of traffic transport industry such as automobile.
For this reason, research and develop a kind of low-density foamed reinforced plastics sheet material,, just become the especially expectation of traffic transport industry of society to realize " to mould Dai Gang " development low-carbon economy.
Summary of the invention
The utility model aims to provide a kind of specializing in and produces enhancing composite plastic sheet material finished product manufacturing enterprise, and used mechanical and physical performance is good, the intermediate materials non-natural continuous filament yarn fabric of stable chemical performance strengthens low-density prefoam plastic plate.
The utility model realizes that the technical scheme of its purpose is:
A kind of non-natural continuous filament yarn fabric strengthens low-density prefoam plastic plate; Its innovative point is; Comprise the first thermoplastic polypropylene plastics and thermoplasticity LDPE blending and modifying prefoam plastic layer; The non-natural continuous filament yarn tissue layer and the second thermoplastic polypropylene plastics and thermoplasticity LDPE blending and modifying prefoam plastic layer are through the said low-density prefoam of three-layer co-extruded one-tenth plastic plate.
Clear by above given technical scheme; The utility model is because its polypropylene and LDPE mix foaming and enhancing modified through it; And with non-natural continuous filament yarn fabric thermoplastic compound sticking; Thereby effectively improved the mechanical and physical performance of the said low-density prefoam of the utility model plastic sheet, really reached light weight, heat insulation, sound insulation, damping, requirement such as fire-retardant, corrosion-resistant, thereby realized the purpose of the utility model.
In technique scheme, the utility model advocates that also the said first blending and modifying prefoam plastic layer and the second blending and modifying prefoam plastic layer all are polypropylene; Low density polyethylene (LDPE), ethene-vinylacetate, Celogen Az; Cumyl peroxide; Zinc oxide, stearic acid, the compound layer of moulding altogether of the different shape material of calcium carbonate and aluminium hydroxide.That is to say that said blending and modifying prefoam plastic layer is to be moulded altogether by the material mixing of the above multiple different shape to form.But be not limited to this.This be the utility model pass through test of many times the excellent technical scheme of preferred cost performance.
In technique scheme, the utility model advocates that also the grammes per square metre that said non-natural continuous filament yarn tissue layer is non-twist alkali-free glass continuous filament yarn fabric is at 250 ~ 300g/m
2In the scope, the glass continuous filament yarn plain of thickness in 0.3 ~ 0.35mm scope.But be not limited to this.Other also all is good such as fabrics such as plastics long filament, carbon filament and copper wires.
In technique scheme, the utility model advocates that also the thickness of said low-density prefoam plastic sheet is in 2.8 ~ 3.5mm scope.When the thickness of said low-density prefoam plastic plate was in 2.8 ~ 3.5mm scope, its foaming thickness was that 4.5 ~ 5mm (reaches thickness 2.8 ~ 3.5mm) just now after the moulding pressurization.
In technique scheme, the utility model advocates that also the said first blending and modifying prefoam plastic layer and the second blending and modifying prefoam plastic layer all are closed pore prefoam plastic layers, and its density is at 0.5 ~ 0.518g/cm
3In the scope.But be not limited to this.In fact, its coefficient of foaming is 2 ~ 2.5 times.The surface of its utility model manufactured goods low-density prefoam plastic plate is the orange peel line with certain degree of hardness.The foam hole that is to say the utility model is a closed pore.The foaming again of this said enhancing composite plastic sheet material of preparation that is the utility model in the back, providing very has good condition, also is the sound insulation that the utility model had, and heat insulation, damping and performance such as corrosion-resistant have been created prerequisite.
After technique scheme was able to implement, characteristics such as mechanical and physical performance that the utility model had and chemical property are good, light weight, recyclable utilization were conspicuous.
