Problems solved by technology

[0007] So far, the mechanical strength problem of PVC foam composite floor has been solved to a large extent. However, there is still a bottleneck in the improvement of the strength of PVC foam composite floor itself, and even if the glass fiber reinforced layer is added, PVC foam composite floor The strength of composite flooring products is also difficult to maintain stably, and defective products with insufficient strength are often produced, resulting in increased production costs
[0008] Such problems are particularly prominent in the field of outdoor flooring. Since outdoor floors tend to reach higher temperatures under the sun, the flexural modulus of PVC foam materials will rapidly decay at high temperatures. Therefore, outdoor flooring The requirements for the strength of PVC foam composite flooring in the field will be further improved, and the existing PVC foam flooring is difficult to meet the use requirements

Embodiment 1

[0060] refer to figure 1 , Enhanced Foam Flooring , the main body is a foam core A made of PVC foam material, two reinforcements B are respectively arranged on the upper and lower surfaces of the foam core A, and the outer periphery of the foam core A is covered with a cylindrical stopper D, the upper surface of the floor is provided with a protective layer C;

[0061] In this embodiment, the reinforcement B is a glass fiber impregnated tape formed by impregnating ABS engineering plastics with glass fibers, the protective layer C is a layer formed of ASA plastic material, and the limiting part D is made of PVC material;

[0062] In the reinforced foam floor described in this embodiment, the vertical section of the foam core A is controlled by the mold to be a rectangle with a length of 140 mm and a width of 24 mm, and its area is 0.336 square decimeters. The maximum number of empty holes whose maximum distance between two points is greater than 0.5 mm is 4, and the number o...

Embodiment 2

[0076] refer to figure 1 , Enhanced Foam Flooring , the technical features are basically the same as those in Embodiment 1. For the convenience of comparison, the exterior specifications of the floor in this embodiment are the same as the floor described in Embodiment 1. The difference is that in the reinforced foam floor described in this embodiment, multiple On the vertical section, the number of empty holes whose maximum distance between any two points is greater than 0.5mm is at most 3, and on most vertical sections, the number of empty holes is 1 or 0.

[0077] refer to Figure 2~Figure 5 , for the preparation of the above-mentioned enhanced foam floor extrusion die , technical feature is basically the same as embodiment 1, the difference is:

[0078] The separated flow channel includes a guide extrusion section 1-1.2 in which the flow channel gradually expands in the extrusion direction of the core material. The end point of the expansion of the guide extrusion sect...

Abstract

The invention relates to a reinforced foaming floor and an extrusion die and equipment set for preparing the reinforced foaming floor, and belongs to the technical field of co-extrusion foaming boards. The reinforced foaming floor comprises a foaming core body and reinforcing pieces; the reinforcing pieces are arranged in the foaming core body or on the surface of the foaming core body in a supporting mode; the number of empty holes in the section of the foaming core body is small; a plurality of separation runners conforming to the flowing direction of a core material are arranged in a core material runner of the extrusion die at intervals; and the equipment set comprises an extrusion die, a core material extrusion device, a reinforcing piece material conveying device, a limiting material extrusion device, a cooling shaping device, a traction device and the like. The prepared reinforced foaming floor has the advantages of high mechanical strength, good stability and low defective rate.

Description

technical field [0001] The invention relates to the technical field of co-extruded foam boards, in particular to a reinforced foam floor, an extrusion die and an equipment set for its preparation. Background technique [0002] Most of the existing composite floors are composed of board materials such as density boards and wood boards and functional layers such as wear-resistant layers. It has a relatively high density and a large weight per unit volume of the floor. Inconvenient, high transportation costs. [0003] For this reason, there is a technical scheme of using foamed PVC materials to replace at least part of the above-mentioned density boards and wood boards to prepare composite floors, such as a weather-resistant PVC floor disclosed in a Chinese utility model patent with the authorization announcement number CN 209603434 U, which includes The wear-resistant layer, stable layer, foam layer and drainage layer from top to bottom are connected by coating and bonding. A...
