Embodiment Construction

[0029] The solutions provided in the present invention are further described by way of examples below.

[0030] 1. Preparation of wear-resistant layer

[0031] The components and parts by weight of the wear-resistant layer are as follows:

[0032]

[0033] The silica airgel powder used in the wear-resistant layer component is a hydrophobic powder of 50-80 μm, with a specific surface area of ​​380m 2 / g or so, the density is 64kg / m 3 . The wear-resistant powder used has an average particle size of 25 μm. The ultraviolet absorber adopts commercially available products, such as series commodities such as phenyl o-hydroxybenzoate, 2,4-dihydroxybenzophenone.

[0034] The preparation method of the wear-resistant layer is as follows: put all the raw materials into the internal mixer for plasticization; then put the plasticized raw materials into the diffusion machine to diffuse until the raw material particles are less than 2mm, the speed of diffusion is 1500r / min, and the dif...

Abstract

The invention discloses a composite PVC table face. The composite PVC table face sequentially comprises an anti-wear layer, a printing layer and a PVC bottom layer; the anti-wear layer is prepared from, in parts by weight, 60-110 parts of resin raw materials, 3-10 parts of silicon dioxide aerogel powder, 1-2 parts of ultraviolet light absorber, 5-10 parts of soybean oil and 4-10 parts of anti-wearadditive; the PVC bottom layer is prepared from 50-80 parts of PVC resin, 25-45 parts of calcium carbonate, 10-20 parts of calcium bicarbonate, 4-8 parts of soybean oil, 25-40 parts of quartz sand, 10-15 parts of modified wood powder and 5-10 parts of nano silicon dioxide. The table face in the invention does not only solve the problems that a homoplasmon PVC table face cannot roll and is hard topave, the appearance of the table face is improved through design of the printing layer, and the appearance visual effect of the table face is greatly changed. Furthermore, the composite table face is thickened, the additionally arranged anti-wear layer prolongs the service life of the composite table face, and thus the beautiful appearance can be maintained durably. The preparation method of thePVC composite table face is simple and reliable, and high in practicality, and is suitable for industrial scale application and popularization.

Description

technical field [0001] The invention relates to the technical field of composite table tops, in particular to a composite PVC table top and a preparation method of the table top. Background technique [0002] PVC countertop is a light home decoration material, which refers to the countertop produced by polyvinyl chloride material, specifically refers to polyvinyl chloride and its copolymer resin as the main raw material, adding fillers, plasticizers, stabilizers, colorants, etc. Auxiliary ingredients, tabletops produced by calendering or coating processes, foundations or extrusions on sheet-like continuous substrates. PVC countertops have the characteristics of bright and beautiful appearance, good wear resistance, dirt resistance and good anti-skid performance. Moreover, PVC countertops have a wide range of raw materials and can be reused at the same time. It is a practical and economical countertop. [0003] Most of the PVC countertops in the prior art are homogeneous PV...
