Example Embodiment

[0034] Embodiment one:

[0035] A flower-to-flower hot-pressing process for stone-plastic flooring, comprising the following steps:

[0036] Step A: Preparation of materials for each layer, manufacturing of the stone-plastic substrate layer, the stone-plastic substrate layer is composed of the following raw materials in parts by weight: 50 parts of polyvinyl chloride, 150 parts of stone powder, 6 parts of calcium zinc stabilizer, 0.35 parts of stearic acid part, 5 parts of PVC modifying agent, 0.2 part of carbon black, 0.6 part of polyethylene wax; Described PVC modifying agent is the acrylic resin taking methylmethacrylate as the main body. The production steps of the stone-plastic substrate layer include: step A1: batching, weighing and mixing polyvinyl chloride, stone powder, calcium zinc stabilizer, stearic acid, PVC modifier, carbon black and polyethylene wax; A2: High-speed heating and stirring, put the mixture in step A1 into the mixer and gradually heat up to 110°C-12...

Example Embodiment

[0043] Embodiment two:

[0044] A flower-to-flower hot-pressing process for stone-plastic flooring. The difference from Example 1 is that the stone-plastic substrate layer is composed of the following raw materials in parts by weight: 65 parts of polyvinyl chloride, 190 parts of stone powder, and 8 parts of calcium-zinc stabilizer. part, 0.65 part of stearic acid, 8 parts of PVC modifier, 0.4 part of carbon black, 0.8 part of polyethylene wax.

Abstract

The invention discloses a pattern aligning hot-pressing process of a stone-plastic floor. The process comprises the following steps that A, all layers of materials are prepared, wherein a stone-plastic base material layer, a wear-resistant layer and a color film layer are produced and manufactured, and when a pattern is printed on the color film layer, and a first cursor is marked on the edge of the color film layer; B, point making of a embossed plate is carried out, and specifically a second cursor is engraved on the pattern position, corresponding to the first cursor on the color film layer, of the bottom surface of the embossed plate; C, pattern alignment is carried out, wherein the embossed plate, the wear-resistant layer, the color film layer and the stone-plastic base material layer are placed from top to bottom, and the first cursor on the color film layer is aligned with the second cursor; and D, hot pressing is carried out, and specifically hot-pressing compounding is carried out on all the layers of materials stacked in the step C by utilizing a hot press. According to the pattern aligning hot-pressing process of the stone-plastic floor, the pattern alignment accuracy between surface embossing of the wear-resistant layer and the pattern of the color film layer can be improved.

Description

technical field [0001] The invention relates to the field of flooring, in particular to a flower-to-floor hot-pressing process for stone-plastic flooring. Background technique [0002] Plastic floor is a floor made of PVC as the main raw material, adding fillers, plasticizers, stabilizers, colorants and other auxiliary materials. During the manufacturing process, the color film layer and wear-resistant layer are generally hot-pressed on the surface of the floor. The decorative function is realized by the color film layer, and the scratch-resistant function is realized by the wear-resistant layer. In order to improve the decorative effect, the color film layer will present simulated patterns, such as some wood grains and annual rings. In order to achieve a better sense of simulation, The embossed board will be used to emboss the concave and convex lines on the surface of the wear-resistant layer to match the corresponding pattern trend, but in the production process, the line...
