Problems solved by technology

It can be seen that this method requires considerable equipment investment only in the foaming process, and the equipment occupies a large area and consumes a lot of energy.
In addition, the thickness error of products manufactured by this technology is relatively large, and the product qualification rate is low

Embodiment 1

[0021] (A) Apply the pre-prepared PVC plasticizing paste to the glass fiber base cloth, and pre-plasticize it on a 160-degree high-temperature rotating strand; after peeling off from the plasticizing drum, use the heat of plasticization to immediately mix The printing layer and the wear-resistant layer are combined to form a semi-finished product, which is ready for use;

[0022] (B) Extrude the foam bottom layer:

[0023] Foam layer raw materials can choose the following materials:

[0024] The PVC resin is made of PVC-SG5 resin with a small degree of polymerization; a small amount of recycled PVC non-foaming products is added; the plasticizer is made of DOP, supplemented with a small amount of epoxy soybean oil; the stabilizer is made of Ca-Zn composite Stabilizer, barium stearate, and SGC-1 are used as foam regulator; lubricant is selected from stearic acid; foaming agent is selected from azodicarbonamide (AC); filler is selected from CaCO 3 For filler.

[0025] Foam lay...

Abstract

The invention discloses a method for preparing calendered and foamed PVC floor leather, comprising the following steps: (A) PVC is pasted and scraped on a glassfiber base cloth and is plasticized; the PVC is stripped from a plasticized rotor drum and then is immediately compounded with a printing layer and a wearing layer to form semi-finished products for standby; (B) a foamed bottom layer is extruded: a. after being gauged according to the formulation, the raw materials for preparing the foamed bottom layer are thrown into a high-speed kneading kettle for kneading to 115-120 DEG C, and then kneaded base materials are put into a cold stirring pot for stirring and cooling to the temperature below 40 DEG C; b. the foam is extruded; c. the foamed bottom layer is prepared; the semi-finished products prepared in the working procedure (A) and the foamed bottom layer prepared in working procedure (B) are compounded and finalized. The method of the invention can reduce the manufacturing cost by above 30%, overcomes the defect of big thickness difference of products caused by foaming of foam furnaces and improves the product percent of pass.

Description

technical field [0001] The invention relates to a preparation method of floor leather, in particular to a preparation method of PVC foamed composite floor leather. Background technique [0002] Currently commercially available PVC floor leather mainly includes all-plastic PVC floor leather, non-woven fabric-based Kang cloth leather and foamed composite floor leather. Foamed composite floor leather is better than ordinary all-plastic floor leather because of its thickness, feel and comfort. In addition, this type of floor has the characteristics of heat preservation, sound insulation, corrosion resistance, wear resistance, easy replacement, and easy cleaning. Therefore, it is favored by consumers. Now the production of foamed floor leather mainly adopts the calendering and foaming technology, which usually includes the following steps: (1) calendering the foaming bottom layer; (2) compounding the transparent wear-resistant layer, the printed pattern layer, and the foaming bo...
