Abstract
The utility model belongs to a clampThe technical field of core color steel plates, in particular to a polyvinyl chloride high-foaming sandwich color steel plate. The technical scheme of the utility model as follows: the polyvinyl chloride high-foaming sandwich color steel plate comprises an upper color steel layer, a lower color steel layer and a sandwich layer between the upper color steel layer and the lower color steel layer, wherein the upper color steel layer and the lower color steel layer are compounded together with the sandwich layer, the sandwich layer is a polyvinyl chloride high-foaming plate, the sandwich layer is formed by splicing more than two polyvinyl chloride high-foaming plates in the width direction and sequentially splicing the polyvinyl chloride high-foaming plates in the length direction in a staggered manner, and the apparent density of the polyvinyl chloride high-foaming plates is less than or equal to 100Kg/m 3 . The sandwich layer of the polyvinyl chloride high-foaming sandwich color steel plate is a polyvinyl chloride high-foaming plate which is an A-grade fireproof material, and the bending strength and the compression strength of the polyvinyl chloride high-foaming plate are superior to those of polyurethane, polystyrene and rock wool plates, and the water absorption rate is low, so that the polyvinyl chloride high-foaming sandwich color steel plate has the advantages of good fireproof performance, high strength and low water absorption rate.
Description
Technical Field
The utility model belongs to the technical field of press from both sides core various steel sheet, concretely relates to various steel sheet of core is pressed from both sides in polyvinyl chloride high foaming.
Background
The color steel sandwich board is a common product in the current building materials, and not only can be good in flame retardant and sound insulation, but also is environment-friendly and efficient. The color steel sandwich board is formed by pressing an upper layer metal panel, a lower layer metal panel and a middle layer high molecular heat insulation inner core. Has the characteristics of simple and convenient installation, light weight, environmental protection and high efficiency. The sandwich of the color steel sandwich plate is mainly polyurethane and polystyrene sandwich, the two sandwich color steel plates have good heat preservation, heat insulation and sound insulation effects, but the polyurethane and polystyrene have poor fireproof performance with the combustion grade of B2, and can release toxic dense smoke during combustion. The use is forbidden in places with high fire protection requirements. A utility model patent that the notice number is CN208069021U discloses a core color steel plate is pressed from both sides in fire prevention, and this kind of core color steel plate is pressed from both sides in fire prevention presss from both sides the core and is rock wool, and rock wool burning grade is A level, and fire behavior is good, can be used to the building that the fire prevention required much. However, the rock wool has high water absorption, is difficult to produce, is easy to agglomerate when meeting water and has short service life; in addition, the rock wool sandwich board has low bending strength and is not suitable for places with high rigidity requirements.
Disclosure of Invention
Not enough to above-mentioned technique, the utility model provides a various steel sheet of core is pressed from both sides in polyvinyl chloride high foaming, it has solved among the prior art that the various steel sheet of core fire prevention level is low, short and the not enough problem of intensity of life.
In order to solve the above problems, the technical scheme of the utility model is as follows: a polyvinyl chloride high-foaming sandwich color steel plate comprises an upper color steel layer, a lower color steel layer and a sandwich layer between the upper color steel layer and the lower color steel layer, wherein the upper color steel layer and the lower color steel layer are compounded together with the sandwich layer, the sandwich layer is a polyvinyl chloride high-foaming plate and is a foam material with a closed-cell porous structure, the sandwich layer is formed by splicing more than two polyvinyl chloride high-foaming plates in the width direction and sequentially spliced in a staggered manner in the length direction, and the apparent density of the polyvinyl chloride high-foaming plates is less than or equal to 100Kg/m 3 The fire rating is A2 rating.
As the improvement, in order to reduce the dead weight of the polyvinyl chloride high-foaming sandwich color steel plate, a plurality of through holes are formed in the polyvinyl chloride high-foaming plate of the sandwich layer along the length direction.
As the improvement, in order to increase the bending strength of the polyvinyl chloride high-foaming sandwich color steel plate, the side surface of the polyvinyl chloride high-foaming plate of the sandwich layer is provided with a hard polyvinyl chloride micro-foaming layer.
As the improvement, the upper color steel plate of the polyvinyl chloride high-foaming sandwich color steel plate is corrugated, and the composite surface of the polyvinyl chloride high-foaming sandwich and the upper color steel plate is provided with the protrusions with the upper color steel plate adapting to the corrugations.
The beneficial effects of the utility model are that:
the sandwich layer of the polyvinyl chloride high-foaming sandwich color steel plate is the polyvinyl chloride high-foaming plate which is an A-grade fireproof material, and the bending strength and the compression strength of the polyvinyl chloride high-foaming plate are superior to those of polyurethane, polystyrene and rock wool plates, so that the polyvinyl chloride high-foaming sandwich color steel plate has the advantages of good fireproof performance, high strength and low water absorption rate.
