Abstract
The invention relates to a manufacturing process of a polypropylene cellular board. The manufacturing method comprises the following steps of: (a) spraying an adhesive on the upper and lower surfaces of a polypropylene cellular core, then laying1-5 layers of polypropylene non-woven cloth, and pressing the whole body uniformly witha pressure of 0.1-0.5kg/cm<2>; and (b) adhering glass fiber reinforced plastic plates with same sizes to the upper and lower surfaces of the polypropylene non-oven cloth, pressing the whole body uniformly with a pressure of 1-2kg/cm<2>, and curing at room temperature. The manufacturing method has simple steps, easy to operate and suitable for industrial production; and the polypropylene cellular board produced by the method has the characteristics of light weight, compression resistance, strong impact resistance, superior sound and heat insulating properties and strong water and corrosion resistance.
Description
Technical field
The present invention relates to a kind of manufacture craft of polypropylene honeycomb plate.
Background technology
Aluminum honeycomb panel is that internal layer adopts special hexagon aluminium honeycomb core, and the aluminium alloy that is reached H19 by hardness forms, and as the central layer sticked in sandwich, bears pressure on tangential.These dense cellular that mutually pin down, just as many little I-beams, can disperse to bear the pressure from the panel direction, make plate stressed evenly, have guaranteed that panel still can keep very high flatness when larger area.Yet aluminium alloy is expensive and quality is heavier, and be not suitable in water content is high and corrosivity is strong environment, finding suitable honeycomb core becomes the task of top priority.
The chemical stability of polypropylene (PP) is fine, outside decapacitation is corroded by the concentrated sulfuric acid, red fuming nitric acid (RFNA), all more stable to other various chemical reagent.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of manufacture craft of polypropylene honeycomb plate, comprise the following steps: (a) in polypropylene honeycomb core upper and lower surface spraying adhesive, paving is applied 1-5 strata propylene nonwoven subsequently, at 0.1-0.5kg/cm
2Under pressure, integral body is evenly exerted pressure; (b) glass epoxy of formed objects is bonded in to the polypropylene non-woven fabric upper and lower surface, at 1-2kg/cm
2Under pressure, whole evenly pressure, at room temperature solidify.
Optimally, described binding agent is a kind of in epoxy resin, polyurethane, phenolic resins.
Because technique scheme is used, the present invention compared with prior art has following advantages:
(1) the method step is simple, and easy operating is applicable to suitability for industrialized production;
(2) with the polypropylene honeycomb plate that the method is produced, have quality light, resistance to compression, anti-impact force are strong, sound insulation, the characteristics that heat-proof quality is superior, water-fast, corrosion resistance is strong.
The specific embodiment
Below will be elaborated to the preferred embodiment of the invention:

(b) glass epoxy of formed objects is bonded in to the polypropylene non-woven fabric upper and lower surface, at 1kg/cm
2Under pressure, whole evenly pressure, at room temperature solidify.
Embodiment 2
This example provides a kind of manufacture craft of polypropylene honeycomb plate, and its concrete steps are as follows:
(a) at polypropylene honeycomb core upper and lower surface spraying polyurethane binding agent, paving is applied 5 strata propylene nonwoven subsequently, at 0.5kg/cm
2Under pressure, integral body is evenly exerted pressure;
(b) glass epoxy of formed objects is bonded in to the polypropylene non-woven fabric upper and lower surface, at 2kg/cm
2Under pressure, whole evenly pressure, at room temperature solidify.
Embodiment 3
This example provides a kind of manufacture craft of polypropylene honeycomb plate, and its concrete steps are as follows:
(a) at polypropylene honeycomb core upper and lower surface spraying phenolic resin adhesive, paving is applied 3 strata propylene nonwoven subsequently, at 0.3kg/cm
2Under pressure, integral body is evenly exerted pressure;
(b) glass epoxy of formed objects is bonded in to the polypropylene non-woven fabric upper and lower surface, at 1.5kg/cm
2Under pressure, whole evenly pressure, at room temperature solidify.
