Abstract
The invention relates to a middle (high) density fiber board-polyurethane foam composite board and the manufacturing method. The composite board is composed of the inflaming retarding middle (high) density fiber board as the panel and the two-component polyurethane foam as the core material. The method step is adopting the middle (high) density fiber board as the mould panel; using the shaped steel or other metal materials to make the mould frame; fixing the mould panel according to the thickness of the composite board; closing the left and the right sides and the bottom of the upper and the lower mould panel; foaming the two-component polyurethane foam in situ; pouring the foaming mixing materials into the die cavity, obtaining the product after the reaction and the rest concreting. The thermal conductivity of the product of the invention reaches 0.029 w/m.k, the sound absorption coefficient is 0.265-0.4; the fire resistance property reaches the standard requirement of the flame resisting materials, with the good effect of inflaming retarding, heat preservation, sound insulation material for the roofing and the wall in the building.
Description
Technical field
The present invention relates to the manufacturing technology of composite sheet, specifically a kind of medium and high density fibre panel-polyurethane foam plastic composite sheet and manufacture method thereof.
Background technique
Building energy conservation and sound insulation dwelling house always are the problem that domestic and international real estate is earnestly paid close attention to.Develop novel insulation, heat insulation, soundproof material is the important channel of greatly developing resource-conserving, environmentally friendly modern building material industry and building industry.At present, having insulation, lightweight composite materials majority heat insulation, sound damping and be with the thermoinsulation material is core, is that plane materiel is composited with the rigid material.Wherein, the thermoinsulation material of the core of getting is mainly has good physical and mechanical property, acoustical behavior, the polyurethane foam plastic of heat-insulating property and chemical-resistance.This is that the composite sheet cost of plane materiel is higher relatively with the rigid material, so scientific and technical personnel both domestic and external have developed rigid polyurethane foam plastics one poplar wood wool composite sheet again, polyurethane compound sandwich composite sheet etc. are as the thermal insulating material of body of wall and roofing; Development is by polyurethane high hardness composite sheet that core and plane materiel the constitute supporting structure material as wall and roof that hard bubbles.It is core with the polyurethane foam plastic that these composite sheets have described too, is the good characteristic of plane materiel composite sheet with the rigid material.
Summary of the invention
The invention provides a kind of medium and high density fibre panel-polyurethane foam plastic composite sheet and manufacture method thereof, purpose is: adopting low fire-retardant medium and high density fibre panel and the two combination polyurethane plastics of thermal conductivity of super quality and competitive price is raw material, makes to meet composite sheet existing civil building standard, that have fire-retardant, insulation, heat insulating function type.
Technical solution of the present invention:
Product of the present invention be with fire-retardant medium and high density fibre panel as panel, be the composite sheet that core constitutes with the polyurethane foam plastic.
The process step of the inventive method is as follows:
(1) the composite sheet panel selects for use.
The present invention adopts the panel of fire-retardant medium and high density fibre panel as composite sheet;
(2) make mould.
(1) by desiring to make the Die and mould plate of the selected above-mentioned fire-retardant medium and high density fibre panel of specification requirement of composite sheet as upper and lower surface; (2) adopt shaped steel or other metal section to make the mould frame, and by the thickness requirement fixed mold plate of desiring to make composite sheet; (3) left and right sides and the bottom surface of sealing upper and lower surface Die and mould plate.
(3) on-the-spot plastic foamed to polyurethane.
Its process step is:
(1) gets bi-component polyurethane ester foamed plastic (can buy), the A component is combined polyether (comprising monomer polyethers and polyester, foam stabilizer, catalyzer, fire retardant and filler), with the B component be isocyanates, the weight proportions of ingredients of A, B component is 1: 1, and is stabilizer with hydrogen fluorine chloric acid;
(2) get and account for stabilizer and the A component that the A ingredients weight parts is 10%-25% and mix, mix with B component isocyanates then, fully stir, 20～30 ℃ of mixture temperatures, mixing time 30-80 second.
(3) the even mixture can with above-mentioned A component, B component and stabilizer enters in the die cavity, and reaction finishes, static 20-28 hour.
(4) demoulding, cutting get finished product.
Beneficial effect of the present invention:
(1) product of the present invention shows through stable state flat band method test, and thermal conductivity reaches that 0.029 (w/m.k) composite sheet thermal conductivity is low, resistance of heat transfer is big; Product shows that through post ripple sound insulation test result the composite sheet acoustic absorptivity is 0.265-0.4; Product flame retarding after tested reaches the requirement of standard GB86-1997 nonflammable material, fire-retardant, the insulation to body of wall and roofing in can be used for building, sound insulating material;
(2) the fire-retardant medium and high density fibre panel of the present invention's employing and two combination polyurethane plastics are raw material, and the product super quality and competitive price help applying in construction industry.
