Problems solved by technology

[0002] Existing architectural decorative tiles generally use brick tiles or single-layer resin tiles. In actual use, due to the heavy weight of brick tiles and single-layer resin tiles, it brings a lot of inconvenience. Large erosion, poor impact resistance, short service life, and poor sound attenuation and heat insulation

preparation example Construction

[0019] The preparation method of double-layer resin glazed tile of the present invention comprises the following steps:

[0020] a. Mix the prepared bottom layer raw materials in a high-speed mixer for 10-15 minutes, then granulate in an extruder at a temperature of 170-200°C; dry the surface layer raw materials at 60-90°C;

[0021] b. Plasticize the above-mentioned pellets at a temperature of 180-210°C;

[0022] c. Extrude the above-mentioned plasticized bottom layer material and dry surface layer material through two co-extrusion machines at 180-200°C, overlap the extruded surface layer and bottom layer, and simultaneously pull it through the traction device and press it with the molding machine type.

Embodiment 1

[0025] a. After mixing 60% polyvinyl chloride resin, 3% foaming agent, 15% impact modifier, 5% lubricant, and 17% processing aid in a high-speed mixer for 10 minutes, the temperature is 170 ° C Granulate in the extruder; dry the surface material modified resin at 60°C; the foaming agent is an azo compound, the impact modifier is chlorinated polyethylene, and the lubricating agent is The agent is oxidized polyethylene wax, and the processing aid is ACR, and ACR (Acrylic copolymer) is an acrylic ester copolymer with a core-shell structure, and is a processing aid with excellent comprehensive performance;

[0026] b. Plasticizing the above-mentioned pellets at a temperature of 180°C;

[0027] c. Extrude and overlap the above-mentioned plasticized bottom layer material and dry surface layer material through two co-extrusion machines at 180°C, and then pull them through a traction device and press them into a molding machine.

Embodiment 2

[0029] a. After mixing 80% polyvinyl chloride resin, 1% foaming agent, 8% impact modifier, 2% lubricant, and 9% processing aid in a high-speed mixer for 12 minutes, the temperature is 180 ° C Granulate in the extruder; dry the surface material modified resin at 80°C; the foaming agent is sodium bicarbonate, the impact modifier is chlorinated polyethylene, and the lubricating The agent is a mixture of oxidized polyethylene wax and paraffin; the processing aid is a mixture of ACR and pigment;

[0030] b. Plasticizing the above-mentioned pellets at a temperature of 200°C;

[0031] c. Extrude and overlap the above-mentioned plasticized bottom layer material and dry surface layer material through two co-extruders at 200°C, and then pull them through a traction device and press them into a molding machine.

Abstract

The invention belongs to the technical field of building material, and more particularly relates to a double-layer resin glazed tile which takes on a sheet shape or a plate shape and is formed by a plurality of wave peaks and/ or wave troughs which are sequentially connected. The glazed tile is formed by a surface layer and a bottom layer, wherein the surface layer is formed by modified resin ASA, and the bottom layer is formed by 60-80% of polyvinyl chloride resin, 1-3% of foaming agent, 8-15% of shock-resistant modifying agent, 2-5% of lubricating agent and 9-17% of processing auxiliary agent by weight percent, wherein the foaming agent is azo-compound or/ and sodium hydrogen carbonate, the shock-resistant modifying agent is chlorinated polyethylene, the lubricating agent is one or mixture of more in oxidized polyethlene wax, stearic acids or paraffin, and the processing auxiliary agent is one or mixture of more in ACR, compound stabilizer, calcium carbonate or pigment. The glazed tile is light in weight and durable, and has good effects of noise reduction and heat insulation.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a double-layer resin glazed tile. Background technique [0002] Existing architectural decorative tiles generally use brick tiles or single-layer resin tiles. In actual use, due to the heavy weight of brick tiles and single-layer resin tiles, it brings a lot of inconvenience. Larger erosion, poor impact resistance, shorter service life, and poor sound attenuation and heat insulation. Contents of the invention [0003] The object of the present invention is to provide a double-layer resin glazed tile, which is light and durable, and has good sound-absorbing and heat-insulating effects. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a double-layer resin glazed tile, the glazed tile is in the shape of a sheet or a plate, and is composed of several successively connected wave crests and / or troughs, and the ...
