Embodiment 1

[0032] Example 1 Effect of plasma treatment on fiber fabric core properties

[0033] Refer to the method disclosed in Example 3 of the patent (application number: 200510025049.3) to prepare the fiber fabric core, wherein the fabric structure of the fiber fabric core is: diameter and weft density: 80×18; radial direction: polyester multifilament fiber linear density 1500D; Weft direction: polyester multifilament density fiber line 2000D; fabric structure is three-dimensional structure.

[0034] Prepare the primer (adhesive layer) with reference to the method of Example 1 in the patent (application number: 200510024772.3).

[0035] Place the obtained fiber fabric core in a vacuum system and irradiate it with a plasma device (see Figure 1). A high-frequency voltage of 300V and 1MHz is applied between the upper and lower electrodes of the plasma device. The working vacuum degree of the vacuum chamber is 60Pa. And the obtained performance indicators are shown in Table 1:

[003...

Embodiment 2

[0039] Embodiment 2 The influence of VP adhesive content on the primer

[0040] Adopt the formula of table 2 to prepare primer, and then detect its bonding strength with the fabric core that is obtained by the method for embodiment 1:

[0041] Table 2

[0042]

[0043]

[0044] The above experimental data show that: the bond strength between the adhesive layer and the fabric core increases with the increase of the alicyclic three-way isocyanate binder component in the formula, but after the alicyclic three-way isocyanate binder component increases to 12phr, the adhesive The increase in bond strength between the layers and the fabric core is no longer evident.

Embodiment 3

[0045] The preparation of embodiment 3 bonding material, surface layer and performance parameter thereof

[0046]According to the formula in Table 3, prepare the bonding material and the surface layer material and test the relevant performance parameters. The preparation method is as follows: mix and swell the liquid synthetic rubber and plasticizer for 20 to 24 hours, then add the stabilizer and stir evenly, then add polyvinyl chloride Stir the resin evenly, vacuumize and defoam; fill the mold cavity with a depth of 1mm and a size of 200mm×200mm and fill it with prepared adhesive or surface material, and scrape it flat; then put the poured mold into the far infrared Heating the oven, and heating according to the conventional production process temperature parameters and heating time parameters; after the ingredients are completely melted, take out the mold to cool, take out the bonding material or surface material sample, and prepare samples for testing according to the test m...

Abstract

The invention relates to a conveyer belt material, in particular to a high strength precise conveyer belt and the preparation of a large-scale machine for conveying ceram and stone, etc. The invention discloses a high strength precise conveyer belt for conveying stone, and the conveyer belt comprises a surface layer, primer material, fiber-textile cores, and bonding material. The invention is characterized in that the top layer of the high strength precise conveyer belt for conveying stone is a surface layer, a plurality of layers of fiber-textile cores are arranged under the surface layer, the bonding material is arranged between the fiber-textile cores which are adjacent to each other, the primer material is arranged between the surface layer and the fiber-textile core which are adjacent to each other, and the primer material is arranged between the fiber-textile core and the bonding material which are adjacent to each other. The invention further provides the preparation method of the conveyer belt as well. The conveyer belt provided by the invention improves the functions of pulling strength, bonding strength between the layers, surface hardness, and abrasion wear, etc. The product is flexible but firm, thereby being able to meet the requirements of the conveyer belts used for a crystallite glass polishing line, a glazed brick polishing line, a porcelain glass-glazed brick polishing line, and a super-cleaning and super-brightening production line.

Description

technical field [0001] The invention relates to conveyor belt materials, in particular to high-strength precision conveyor belts for large machinery such as ceramics and stone materials and their preparation. Background technique [0002] The architectural ceramics industry is a typical industry with high energy consumption, high resource consumption and high environmental pollution. Glass-ceramics and large ultra-thin building ceramic tiles are of great significance for saving energy and resources, improving environmental pollution, and improving the economic benefits of the industry. They are a great revolution in the entire ceramic field. In order to produce such products, leading technology companies in the world's building materials and equipment industry have launched new "glass-ceramics polishing lines", "glazed tile polishing lines", "porcelain vitrified tiles" with "energy saving, low consumption, high efficiency, and environmental protection". Polishing line" and ...
