Problems solved by technology

Its shortcoming is that it uses a single resin matrix, and the comprehensive performance of the material is insufficient. Only the flame retardant performance of the floor is considered, and the addition of a large number of halogen-free flame retardants reduces the mechanical properties and wear resistance of the material, and also increases the manufacturing cost.
Both of the above two patent applications did not consider the need for sound insulation and noise reduction performance of the floor used in the field of rail transit

preparation example Construction

[0067] In a specific embodiment, the preparation method of the sound-insulating elastic coil floor for rail transit comprises the following steps:

[0068] Internal mixing: The configured and weighed sound insulation layer and wear-resistant layer materials are internally mixed with an internal mixer respectively. It is required that the resin is melted and plasticized, and all materials are mixed evenly. The internal mixing temperature is controlled at 180°C to 220°C.

[0069] Extrusion or calendering: Extrude or calender the plasticized and mixed sound-insulating layer and wear-resistant layer materials respectively into sheets of certain width and thickness, and the extrusion or calendering temperature is 160°C to 210°C.

[0070] Composite: The sound insulation layer sheet, the glass fiber stable layer mesh cloth and the wear-resistant layer sheet are compositely formed by hot rolling. The hot rolling temperature is 150℃~180℃. After cooling, the composite sheet needs to be p...

Abstract

The invention discloses a sound insulation type elastic coiled material floor for rail transit and a preparation method of the sound insulation type elastic coiled material floor. The sound insulationtype elastic coiled material floor is formed by hot-pressing compounding of a sound insulation layer and a wear-resistant layer, the sound insulation layer is prepared from the following components including,10-30 parts of polyolefin elastomer, 5-25 parts of styrene elastomer, 60-150 parts of heavy filler, 20-100 parts of a flame retardant and 2-6 parts of auxiliaries, and the wear-resistant layer is prepared from the following components including, 5-30 parts of polyolefin elastomer, 10-30 parts of styrene elastomer, 5-30 parts of wear-resistant reinforced resin, 10-60 parts of a flame retardant, 1-8 parts of a compatilizer, 2-15 parts of a wear-resistant agent and 2-5 parts of auxiliaries. Through compounding of the sound insulation layer and the wear-resistant layer, the sound insulation performance of the coiled material floor is greatly improved, additional use of sound insulation materials is reduced, the comprehensive cost is reduced, the coiled material floor has lower smoke density and smoke toxicity, zero plasticizer addition can be achieved, and the coiled material floor has very good environmental friendliness.

Description

technical field [0001] The invention relates to an elastic coil floor and a preparation method thereof, in particular to an elastic coil floor with good sound insulation performance and a preparation method thereof, which are applied in the rail transit field. Background technique [0002] Coiled flooring (also known as floor leather) is a very popular light-weight floor decoration material today, widely used in homes, offices, public places, public transportation and other fields. According to the material, the coiled floor is mainly divided into PVC floor (also called plastic floor) and rubber floor. Among them, PVC plastic flooring is more widely used. PVC plastic flooring can be divided into two types according to its structure. One is a homogeneous and transparent structure, that is, the same color and material from the surface to the bottom, and the other is a composite structure. Including pure PVC transparent wear-resistant layer, printing layer and reinforcement la...
