Description

Technical Field

[0001] The invention belongs to the field of anti-skid waterproof coiled materials, and more specifically, relates to an anti-skid coating and its preparation and application, and an anti-skid self-adhesive waterproof coiled material. Background Art

[0002] The friction of the waterproofing membrane surface should be considered when people need to go up to operate the membrane, so as to ensure the personal safety of the operators. Especially for the construction of sloped roof waterproofing membrane, the membrane is laid under the condition of slope and height. The friction of the membrane surface can help the operators work more stably on the operating surface and avoid the risk of falling and injury. The currently available full-text mandatory "General Specification for Waterproofing of Buildings and Municipal Engineering" GB 55030-2022 requires that when the roof slope is greater than 30%, anti-slip measures should be taken during the construction process. "Technical Specification for Sloped Roof Engineering" GB / T 50693-2012 requires that a waterproof cushion layer should be selected for tile roofs, and at the same time proposes that the surface of the waterproof cushion layer should have anti-slip properties or take anti-slip measures.

[0003] The most common surface treatment method for anti-skid waterproof membranes on the market is physical anti-skid, that is, directly creating macroscopically visible concave and convex patterns on the surface of the material to increase the surface roughness. Usually, this method has little effect on improving friction. In addition, the concave and convex patterns on the surface reduce the bonding surface area, thereby reducing the bonding and sealing performance of the overlapped edges.

[0004] Therefore, a new anti-slip coating and its preparation and application are urgently needed to be proposed. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies of the prior art and to provide an anti-slip coating, preparation and application thereof, and an anti-slip self-adhesive waterproof roll. The present invention adopts a combination of chemical anti-slip and physical anti-slip to prepare an anti-slip coating, which can significantly improve the friction of the roll surface, and will not affect the bonding effect of the overlapped edge of the roll, but can improve the bonding and sealing performance of the overlapped edge to a certain extent.

[0006] In order to achieve the above object, the first aspect of the present invention provides an anti-slip coating, wherein the content of polar groups in the anti-slip coating formulation is not less than 2% based on the total weight of the anti-slip coating formulation; the polar groups are at least one of carbonyl, carboxyl, amide, carbamate, urea and halogen atoms;

[0007] The upper surface of the anti-slip coating has a micron-level texture, the embossing depth is less than 500 μm, and the convex width is less than 2 mm.

[0008] According to the present invention, preferably, the formulation system of the anti-slip coating comprises a polar group elastomer, a petroleum resin, and at least one of alkane oil, wax, an additive and a viscoelastic elastomer, and the polar group is derived from the polar group elastomer.

[0009] According to the present invention, preferably, based on the total weight of the formulation system of the anti-slip coating, the content of the polar group elastomer is 10-80%, the content of the petroleum resin is 10-80%, the content of the alkane oil is 0-30%, the content of the wax is 0-40%, the content of the additive is 0-5%, and the content of the viscoelastic elastomer is 0-10%.

[0010] According to the present invention, preferably, based on the total weight of the formula system of the anti-slip coating, the content of the polar group elastomer is 10-60%, the content of the petroleum resin is 40-60%, the content of the alkane oil is 5-30%, the content of the wax is 5-15%, the content of the additive is 0.1-1%, and the content of the viscoelastic elastomer is 5-10%.

[0014] According to the present invention, preferably, the wax is at least one of PE wax, paraffin wax, Fischer-Tropsch wax and microcrystalline wax. In the present invention, paraffin wax and microcrystalline wax are generally less heat-resistant than PE wax and Fischer-Tropsch wax, because paraffin wax and microcrystalline wax have low crystallinity and low molecular weight, while PE wax and Fischer-Tropsch wax have higher molecular weight and cleanliness, therefore, PE wax and Fischer-Tropsch wax are helpful to improve the heat resistance of the formulation system. In the present invention, the selection of wax can be combined according to the heat resistance performance requirements of the formulation system of the anti-slip coating.

[0015] According to the present invention, preferably, the auxiliary agent is an antioxidant auxiliary agent and / or an anti-ultraviolet aging auxiliary agent.

[0016] According to the present invention, preferably, the viscoelastic elastomer is selected from a material having excellent viscoelasticity and gripping properties, and is at least one of polyisobutylene rubber (PIB), styrene-butadiene rubber and ethylene-propylene-diene rubber (EPDM).

[0017] According to the present invention, preferably, the embossing depth is less than 100 μm, preferably less than 50 μm.

[0018] According to the present invention, preferably, the protrusion width is less than 0.5 mm, preferably less than 100 μm.

[0019] According to the present invention, preferably, the coating weight of the anti-slip coating is 5-100 g / m 2 , preferably 5-50g / m 2 .

[0020] According to the present invention, preferably, the Shore A hardness of the anti-slip coating measured according to GB / T 531.1 is 50-90HA (at 23°C), the dry and wet anti-slip coefficient of the anti-slip coating measured according to JC / T 1050-2007 "Classification and Test Methods for Anti-slip Performance of Ground Stone" is higher than 0.5, and the needle penetration of the anti-slip coating measured according to GB / T 4509 is less than 90dmm (at 23°C).

[0021] The second aspect of the present invention provides a method for preparing the anti-slip coating, which comprises kneading and mixing the formula system of the anti-slip coating, and sequentially performing hot-melt coating, embossing treatment and cooling to obtain the anti-slip coating.

[0022] According to the present invention, preferably, the internal mixing equipment comprises an internal mixer, the internal mixing temperature is 120-200°C, the mixing time is 8-12 min, and the mixing stirring speed is 25-35 rpm.

[0023] According to the present invention, preferably, the temperature of the hot melt coating is 100-180°C; and the temperature of the coating obtained after the hot melt coating is above 50°C.

[0024] According to the present invention, preferably, the embossing equipment comprises an embossing roller, and the temperature of the embossing roller is 50-120°C.

[0025] According to the present invention, preferably, the cooling is to cool the temperature of the coating obtained after the embossing treatment to 21-25°C.

[0026] According to the present invention, preferably, the preparation method further comprises: coating the upper surface of the anti-slip coating with a layer of anti-sticking release film, and then rolling it up.

[0027] The third aspect of the present invention provides the use of the anti-slip coating on anti-slip packaging, anti-slip self-adhesive waterproof coiled materials and anti-slip conveyor belt surfaces.

[0028] In the present invention, the friction between the anti-slip coating surface and the human body contact surface is mainly generated by three aspects:

[0029] 1. The polar groups in the formula system of the anti-slip coating can help provide adhesion to the contacting objects and increase the interlayer friction by relying on intermolecular forces.

[0030] Second, the elastic deformation of the anti-slip coating can increase the tangential force between the contact surface and thus increase the friction.

[0031] 3. The upper surface of the anti-slip coating is a micron-level texture, such as Figure 1 As shown, the embossing depth h is less than 500 μm, and the convex width w is less than 2 mm, which increases the roughness of the coating, thereby increasing the intermolecular friction. The micron-level texture mainly affects the friction at low speed (10 km / h), which corresponds to the speed of human movement. In addition, in the presence of water, water will be unevenly aggregated on low polarity or hydrophobic surfaces, thereby reducing the actual contact area and greatly reducing the interlayer friction. The anti-slip coating of the present invention has a large number of polar groups, which is conducive to the spreading of water film, thereby improving the friction in the presence of water.

[0032] A fourth aspect of the present invention provides an anti-slip self-adhesive waterproof roll material, the waterproof roll material comprising a release film, a first self-adhesive layer and a polymer film, and optionally a second self-adhesive layer and a tire base fabric;

[0033] The release film, the first self-adhesive layer and the polymer film are arranged in sequence from bottom to top; optionally, the release film, the first self-adhesive layer, the tire base fabric, the second self-adhesive layer and the polymer film are arranged in sequence from bottom to top;

[0034] The upper surface of the polymer film is divided into an overlapping edge region and a non-overlapping edge region;

[0035] The non-overlap edge area is provided with the anti-slip coating;

[0036] The overlapping edge region is provided with the anti-slip coating, or the upper surface of the polymer film in the overlapping edge region is not provided with any coating.

[0037] According to the present invention, preferably, an isolation film may be provided on the anti-slip coating layer.

[0038] According to the present invention, preferably, the release film is a single-sided release film or a double-sided release film.

[0039] According to the present invention, preferably, the materials of the first self-adhesive layer and the second self-adhesive layer are independently at least one of styrene block copolymer hot melt pressure-sensitive adhesive, butyl self-adhesive, modified asphalt adhesive, acrylic pressure-sensitive adhesive, silane-modified pressure-sensitive adhesive and polyurethane pressure-sensitive adhesive.

[0040] According to the present invention, preferably, the thickness of the self-adhesive layer is more than 10 times the embossing depth, and preferably, the thickness of the self-adhesive layer is more than 20 times the embossing depth.

[0041] In the present invention, the micron-scale texture on the upper surface of the anti-slip coating does not affect the bonding area of ​​the self-adhesive layer, and can also increase the bonding area between the self-adhesive layer and the anti-slip coating to a certain extent. At the same time, the higher polarity of the anti-slip coating can improve the adhesion with the self-adhesive layer, thereby improving the bonding strength of the overlapping surface of the self-adhesive layer and improving the sealing performance of the overlapping edge of the coiled material.

[0042] According to the present invention, preferably, the thickness of the polymer film is 0.05-1.5 mm.

[0043] According to the present invention, preferably, the polymer film is a polymer film that has been subjected to double-sided corona treatment, and its double-sided corona value is higher than 38.

[0044] According to the present invention, preferably, the material of the polymer film is at least one of polyolefin homopolymer, polyolefin copolymer, ethylene-vinyl acetate copolymer, polyvinyl chloride, polyester, polyamide and polyurethane.

[0045] In the present invention, as a preferred embodiment, the method for preparing the anti-slip self-adhesive waterproof coiled material comprises:

[0046] The anti-slip coating is hot-melt coated on one side of the polymer film, and then the self-adhesive layer is coated on the other side of the polymer film, and then compounded with a release film; or; the self-adhesive layer is coated on the release film and then transferred to the side of the polymer film that does not contain the anti-slip coating; or, after the self-adhesive layer is coated on the upper and lower surfaces of the tire base cloth, the first self-adhesive layer is compounded with the release film, and the second self-adhesive layer is compounded with the side of the polymer film that does not contain the anti-slip coating.

[0047] Alternatively, the polymer film containing the anti-slip coating is directly rolled up after preparation, and then coated with self-adhesive on other production lines to prepare the self-adhesive roll.

[0048] The beneficial effects of the technical solution of the present invention are as follows:

[0049] The anti-skid coating of the present invention can significantly improve the anti-skid performance of the anti-skid self-adhesive waterproof coiled material, and improve the safety of construction workers on the surface of the coiled material. At the same time, the adhesion performance of the overlapped edge is not lost, and the sealing performance of the overlapped edge can be improved to a certain extent.

[0050] The anti-skid coating of the present invention has a wide range of applications and can be applied on a variety of substrates, such as anti-skid packaging, anti-skid coils, anti-skid conveyor belts and other materials that require surface anti-skid treatment.

[0051] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS
