Problems solved by technology

Analyzing its reason, those skilled in the art find that other groups such as ester group, hydroxyl etc. are contained in the material used in the existing rigid polyvinyl chloride decoration material formula, and these groups are very easy to react with water, and its The refractive index of the reaction product is very different from that of polyvinyl chloride, which causes the product to become whitish and foggy. Even if it is made into a film or sheet, it cannot completely prevent the occurrence of this reaction, thus causing whitening of sensitive water. phenomenon, which greatly affects the appearance and performance of PVC decorative materials, and cannot achieve the effect of decorating the surface of objects, and this situation is particularly prominent on black plastics.

Embodiment 1

[0043] Embodiment 1. The preparation of rigid polyvinyl chloride product 1

[0044] like figure 1 As shown, the preparation method of the rigid polyvinyl chloride product of the present invention includes a high-speed stirring and mixing process, a low-speed stirring and cooling process, a planetary multi-screw extrusion process, a single-screw extrusion and filtration process, a calendering process, and a liquid cooling tank. Chilling process, annealing heat preservation and warming process, cooling process and finished product coiling process; its special feature is that in this embodiment, each component of the rigid polyvinyl chloride product and the component content in parts by mass are shown in the table 1 shows:

[0045] Components and content (parts by mass) of the rigid polyvinyl chloride product of Table 1 Example 1

[0046] Polyvinyl chloride (PVC) 100 parts,

[0047] Mercaptan organotin 1.6 parts,

[0048] Acrylic ester internal lubricant 0.6 part,

[0049] A...

Embodiment 2

[0054] Embodiment 2. Preparation 2 of rigid polyvinyl chloride products

[0055] Component and content (parts by mass) of the PVC bottom film of table 2 embodiment 2

[0056] Polyvinyl chloride (PVC) 100 parts,

[0057] Mercaptan organotin 1.8 parts,

[0058] Acrylic ester internal lubricant 0.8 parts,

[0059] Acrylic external lubricant 0.3 parts,

[0060] 10 parts of methyl methacrylate-butadiene-styrene copolymer,

[0061] Hydroxy-terminated linear reactive siloxane 0.3 parts

[0062] Rutile titanium dioxide 8.0 parts

[0063] Ultramarine EP-19 0.018 parts

[0064] According to the components and contents in Table 2, the rigid polyvinyl chloride product produced by the method in Example 1, because no plasticizer is needed, and the hydroxyl-terminated linear reactive silicone containing hydrophobic group is added Alkanes can significantly block the erosion of water molecules on the film, and better solve the problem of water-sensitive whitening on the surface of plastic...

Embodiment 3

[0065] Embodiment 3. Preparation 3 of rigid polyvinyl chloride products

[0066] Component and content (parts by mass) of the PVC bottom film of table 3 embodiment 3

[0067] Polyvinyl chloride (PVC) 100 parts,

[0068] Mercaptan organotin 2.2 parts,

[0069] 1.0 part of acrylic internal lubricant,

[0070] 0.5 parts of acrylic external lubricant,

[0071] 14 parts of methyl methacrylate-butadiene-styrene copolymer,

[0072] Fluorine resin 0.5 parts

[0073] Rutile titanium dioxide 1.0 parts

[0074] P.V.19 red pigment 4.0 parts

[0075] P.R.122 red pigment 0.9 parts

[0076] According to the components and contents in Table 3, the rigid polyvinyl chloride products produced by the method in Example 1 can significantly block water due to the addition of plasticizers and the addition of fluororesins containing hydrophobic groups. The erosion effect of molecules on the film can better solve the problem of water-sensitive and whitening of the surface of plastic products. ...

Abstract

The invention discloses a rigid polyvinyl chloride product, which contains the following components in parts by mass: 100 parts of polyvinyl chloride, 1.6-2.2 parts of organic tin mercaptan, 0.6-1.0 parts of internal lubricant, and 0.2-2.2 parts of external lubricant. 0.5 parts, 6-14 parts of impact modifier, 0.2-0.5 parts of waterproof modifier, and add appropriate amount of pigment. The invention also discloses a preparation method of the rigid polyvinyl chloride product. In the hard polyvinyl chloride product formula of the present invention, do not add any plasticizer, have avoided the phenomenon that the surface of the polyvinyl chloride product is sensitive to water and become white due to the influence of the ester group of plasticizer; In addition, in the hard polyvinyl chloride product of the present invention The formula of high-quality polyvinyl chloride products contains a hydrophobic base waterproof modifier, which significantly improves the solvent resistance and permeability resistance of polyvinyl chloride products, effectively isolates the erosion of external water or water vapor, and protects the polyvinyl chloride products. The surface of vinyl products makes it have good appearance performance.

Description

technical field [0001] The invention relates to a polyvinyl chloride (PVC) material and a preparation method thereof, in particular to a rigid polyvinyl chloride product and a preparation method thereof. Background technique [0002] In daily life, it is often necessary to add decorative materials on the surface of the object to meet people's pursuit of the appearance of the object, and at the same time, it can also play a certain protective role. Among them, for high-gloss decorative materials, due to their high requirements on surface color and appearance, the colored decorative materials disclosed in the prior art generally have the problem of water-sensitive whitening, that is, those prepared by the prior art The rigid polyvinyl chloride decorative materials (including films and sheets, etc.), after being made into finished products, will more or less form a white mark on the surface of the film after encountering water vapor or soaking in water. It greatly affects the ...
