Problems solved by technology

[0003] Although the PVC floor has the above advantages, the single PVC floor has certain limitations in the sound insulation effect.
In order to improve the sound insulation effect of PVC flooring, there are currently many related researches. There are structures designed to reduce noise by adding multiple composite layers such as sound insulation layers and moisture-proof layers. However, there are high preparation costs and the adhesion of each layer. Not good, and it is prone to defects such as warping and peeling; in addition, there is also a practice of pasting foam materials behind wooden floors, but when applied to PVC floors, how to solve the temperature, speed, glue volume and pressure during the bonding process The control of process parameters will have a decisive impact on the peel strength and warpage performance indicators of the product

Embodiment 1

[0027] Please refer to figure 1 , a preparation method of a sound-insulating rigid PVC floor, specifically, a PE foam board with a thickness of 1.0mm is adhered to the back of an ordinary PVC floor with 4 layers of foam material for preparation, comprising the following steps:

[0028] (1) Film production: firstly, after the raw materials are inspected and qualified, according to the ordinary PVC floor formula and film production method, it is drawn through the process of cold mixing and hot mixing, banburying, four-roll calendering, cooling and winding of the compounding materials. Negative films of various required specifications and thicknesses;

[0029] (2) Continuous line bonding: After the temperature rises to the specified value, the material is worn layer by layer in the order of negative film, surface layer, color film, and transparent sheet. The number of layers of each layer depends on the thickness requirements of the prepared floor and the thickness of the transpa...

Embodiment 2

[0043] Please refer to figure 1 , a method for preparing a sound-insulating rigid PVC floor, specifically, a PE foam board with a thickness of 2.0mm is attached to the back of an ordinary PVC floor with 4 layers of foaming material for preparation, including the following steps:

[0044] (1) Film production: firstly, after the raw materials are inspected and qualified, according to the ordinary PVC floor formula and film production method, it is drawn through the process of cold mixing and hot mixing, banburying, four-roll calendering, cooling and winding of the compounding materials. Negative films of various required specifications and thicknesses;

[0045] (2) Continuous line bonding: After the temperature rises to the specified value, the material is worn layer by layer in the order of negative film, surface layer, color film, and transparent sheet. The number of layers of each layer depends on the thickness requirements of the prepared floor and the thickness of the trans...

Abstract

The invention discloses a preparation method for a soundproof hard PVC floor. Aiming at the poor soundproof effect of existing PVC floors and various defects existing in existing soundproof PVC floor preparation, preparation is conducted by adhering a foaming material to the back face of a common PVC floor; the floor is prepared through the technological processes of base piece production, continuous attachment, surface production, hot melt adhesive attachment, standing, punching, slotting, packing and product performance detection; the technological steps of all the processes of continuous attachment and hot melt adhesive attachment and the technological parameters including time, temperature and humidity, the speed, pressure and the like are intensively optimized; the prepared hard PVC floor is good in texture, soundproof effect and flatness, size stability of the floor is effectively improved, peeling strength and warping of the floor both accord with national or industrial standards; and additionally, the preparation method further effectively reduces the production cost.

Description

technical field [0001] The invention relates to the field of floor preparation, in particular to a preparation method of sound-insulating rigid PVC floor. Background technique [0002] PVC floor, also known as "light floor material", also known as plastic floor, is a new type of light floor decoration material. It is a popular product in Europe, America, Asia, Japan and South Korea, and has been gradually introduced into the Chinese market. It is widely used in various places such as families, hospitals, schools, office buildings, factories, public places, supermarkets, and businesses. PVC floor refers to the floor made of polyvinyl chloride material. Specifically, polyvinyl chloride and its copolymer resin are used as the main raw material, and fillers, plasticizers, stabilizers, colorants and other auxiliary materials are added to the sheet continuous substrate. Coating process or produced by calendering, extrusion or extrusion process. [0003] Although the PVC floor ha...
