Abstract
The invention discloses a composite wallboard and a manufacturing method. The composite wallboard comprises a wallboard substrate and a sandwich layer, wherein the wallboard substrate is integrally mouled into a strip once and comprises a hollow cavity for moulding the sandwich layer; a groove is arranged on one side of a long edge of the wallboard substrate; a convex groove is arranged at the other side of the long edge; the groove is tightly meshed with the convex groove, and the sandwich layer is polyurethane hard foam and foamed and moulded once in the hollow cavity of the wallboard substrate. The composite wallboard disclosed by the invention selects the polyurethane hard foam as the sandwich layer, is light in weight, good in heat preservation and sound insulation effects; the groove is arranged on one side of the long edge of the composite wallboard and the convex groove is arranged on the other side, so the installation is convenient and firm.
Description
Technical field
The present invention relates to technical field of buildings, the manufacturing approach of particularly a kind of combined wall board and a kind of combined wall board.
Background technology
Existing building selects for use polyphenyl plate, foam cement or extruded sheet etc. to do the core material with partition wall batten, and these core material face density are bigger, and the weight of unit area body of wall is also big.And through the cementing agent bonding, insulation is bad with soundproof effect, complicate fabrication process between core and the plate face.
Summary of the invention
The technical problem that the present invention will solve is existing partition wall batten Heavy Weight, and insulation and soundproof effect are bad.
To achieve these goals; The invention provides a kind of combined wall board, comprise plate face base material and sandwich of layers, said plate face base material global formation becomes strip; Comprise the cavity that is used for the sandwich of layers moulding; One side on the long limit of plate face base material is a groove, and the opposite side on long limit is a tongue, the tight interlock of groove and tongue; Said sandwich of layers is a hard polyurethane foam, and foaming forms in the cavity of plate face base material.
Alternatively, said plate face base material is fiber reinforced cement board, silica-magnesia panel or calcium silicate board.
Alternatively, said hard polyurethane foam disposable foaming in the cavity of plate face base material forms.
Alternatively, the raw material of said hard polyurethane foam comprises: polyethers or PEPA, polyisocyanates, water, catalyzer, surfactant and blowing agent.
The present invention also provides a kind of manufacturing approach of combined wall board, comprises the steps:
Step (a), the Integratively formed plate face base material of processing strip, plate face base material comprises cavity, and a side on the long limit of plate face base material is a groove, and the opposite side on long limit is a tongue, the tight interlock of groove and tongue;
Step (b) is processed sandwich of layers through the polyurethane foam moulding in the cavity of plate face base material.
Alternatively, select for use fiber reinforced cement board, silica-magnesia panel or calcium silicate board as plate face base material.
Alternatively, in the cavity of plate face base material, process sandwich of layers through disposable polyurethane foam moulding.
Alternatively, with disposable addings of raw material such as polyethers or PEPA, polyisocyanates, water, catalyzer, surfactant and blowing agents, mix the back in high-speed stirred and in the cavity of plate face base material, carry out foaming.
The invention has the beneficial effects as follows:
(1) combined wall board selects for use hard polyurethane foam to do sandwich of layers, and is in light weight, and insulation is good with soundproof effect;
(2) long limit one side of combined wall board is a groove, and opposite side is a tongue, and is easy for installation, firm.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structure chart of combined wall board of the present invention;
Fig. 2 is the flow chart of combined wall board manufacturing approach of the present invention.
The specific embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Fig. 1 is the structure chart of combined wall board of the present invention.
As shown in Figure 1, combined wall board comprises plate face base material 101 and sandwich of layers 102.
Plate face base material 101 is a monolithic construction, through the Integratively formed strip of processing of mould, comprises the cavity of hollow, and plate face base material 101 comprises long limit and minor face, and a side on long limit is a groove, and the opposite side on long limit is a tongue, the tight interlock of groove and tongue.During installation, the tongue of a back combined wall board inserts the groove of last combined wall board, so that two combined wall boards are combined closely.Interlock place of tongue and groove can bond with binding material, and bond effect is better.Plate face base material can be fiber reinforced cement board, silica-magnesia panel or calcium silicate board.
Sandwich of layers 102 is a hard polyurethane foam; Be in the cavity of plate face base material 101, to form through disposable foaming; Particularly; With disposable addings of raw material such as polyethers or PEPA, polyisocyanates, water, catalyzer, surfactant and blowing agents, after high-speed stirred is mixed, in the cavity of plate face base material 101, carry out foaming.Sandwich of layers 102 behind the foaming fits tightly with plate face base material 101, does not need extra bonding process process.Sandwich of layers 102 of the present invention also can be passed through prepolymer method or semi-prepolymer method foaming, and those skilled in the art can select any suitable foam process for use.
Shown in Figure 2 is the flow chart of combined wall board manufacturing approach of the present invention.
As shown in Figure 2, combined wall board manufacturing approach of the present invention may further comprise the steps:
Step (a), through the Integratively formed plate face base material of processing strip of mould, plate face base material comprises cavity, and a side on the long limit of plate face base material is a groove, and the opposite side on long limit is a tongue, the tight interlock of groove and tongue;
Step (b) is processed sandwich of layers through the polyurethane foam moulding in the cavity of plate face base material.
