Description

Technical Field

[0001] The present invention relates to the technical field of novel functional safety protection materials, and in particular to a resin fabric composition and a preparation method thereof. Background Art

[0002] my country is a major economy with the world's largest workforce and the broadest range of industries. It is a leading manufacturer and user of labor protection equipment (personal protective equipment). Across numerous industries requiring labor protection equipment, including petroleum, petrochemicals, chemicals, oil depots, gas stations, fireworks and firecrackers, power plants, substations, power grids, coal and non-coal mining, construction, metallurgy, steel, foundry, shipbuilding, equipment manufacturing, machining, automotive, pharmaceuticals, cement, flour processing, grain storage, sanitation, transportation, and agriculture, the number of workers in these industries exceeds 200 million, representing enormous potential for development.

[0003] At the same time, with the improvement of material living standards, people's awareness of self-protection is getting stronger and stronger, and they have put forward higher requirements for the safety and protective performance of textiles. The development of textiles shows a trend towards high-tech textiles, and new functional safety and protection materials have emerged.

[0004] According to research, the main mechanical damage-resistant safety protection materials currently on the market include metal fiber filaments (such as stainless steel wire and chrome alloys), specialty fibers (such as aramid fibers Kevlar, Spectra, and HPPE), coatings (such as nitrile with fabric lining, polyurethane with fabric lining, natural latex with fabric lining, PVC with fabric lining, silicone with fabric lining, and neoprene with fabric lining), leather, and canvas. While these materials offer some protective properties, they also have significant drawbacks. For example, metal fiber is inflexible, heavy, and expensive, with limited application; specialty fibers are expensive and have a very low civilian adoption rate; nitrile and polyurethane coatings have poor mechanical damage resistance; leather is not breathable; and canvas is thick, heavy, and inflexible, also limiting its application. Furthermore, these protective materials offer poor puncture resistance, making them particularly ineffective against needle punctures. Summary of the Invention

[0005] The present invention makes a breakthrough improvement in view of the shortcomings and deficiencies of the above-mentioned prior art. That is, the embodiment of the present application solves the shortcomings of the mechanical damage-resistant safety protection materials in the prior art, such as single function, poor wearing comfort, narrow scope of application, and high price, by providing a resin fabric composition and a preparation method thereof.

[0006] In addition, the present invention also provides a method for preparing a resin fabric composition, which has a simple resin slurry preparation method, a mature printing process, stable and reliable performance, low initial investment, and is suitable for large-scale industrial production.

[0007] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0008] A resin fabric composition comprises a resin portion and a fabric portion. The resin portion is composed, by weight, of the following components: 100 parts resin, 3-35 parts resin hardener, 60-150 parts functional filler, 3-12 parts rheological agent, 5-20 parts coupling agent, and 1.5-10 parts dye.

The resin fabric composition comprises the resin printed onto the fabric using a printing technique.

[0009] Further preferably, a resin fabric composition is provided, which consists of a resin part and a fabric part, wherein the resin part is prepared from the following components in parts by weight: 100 parts of epoxy resin or phenolic resin, 4 to 29 parts of resin hardener, 65 to 140 parts of functional filler, 4 to 10 parts of rheological agent, 5.5 to 18 parts of coupling agent, and 2.5 to 8.5 parts of dye; the resin fabric composition, that is, the prepared resin slurry is printed on the fabric by steel screen printing technology, and is firmly bonded to the fabric after an in-situ high-temperature curing reaction.

Specifically, it is preferably one or a suitable combination of dicyandiamide and its derivatives, organic acid hydrazides, BF3 amine complexes, diaminomaleonitrile and its derivatives, and imidazole compounds.

[0012] Preferably, the resin hardener may be a non-latent curing agent, specifically, one or a suitable combination of amines and their derivatives (such as aliphatic amines, aromatic amines, alicyclic amines, polyether amines, etc.), acids or anhydrides and their derivatives (such as maleic anhydride, dimer acid) compounds.

[0013] Further preferably, the functional filler can be selected from one or more wear-resistant fillers (preferably one or more appropriate combinations of graphite, molybdenum disulfide, silicon micropowder, aluminum oxide, corundum, silicon carbide, aluminum oxide, zirconium oxide, and ceramics), one or more flame retardant fillers (preferably one or two appropriate combinations of aluminum oxide, calcium carbonate, barium hydroxide, aluminum hydroxide, and red phosphorus), one or more heat-resistant fillers (preferably one or more appropriate combinations of magnesium hydroxide, boron nitride, aluminum trihydrate, and kaolin), one or more electrical-resistant fillers (preferably one or more appropriate combinations of silica, calcium silicate, aluminum oxide, and asbestos), one or more inorganic antibacterial and anti-mildew agents (preferably one or more appropriate combinations of silver ion antibacterial agents (such as nanosilver), borax, zinc oxide, copper oxide, ammonium dihydrogen phosphate, and lithium carbonate), or any one or more appropriate combinations thereof; further preferably, the filler particle size is 10~1000nm.

[0014] Further preferably, the rheological agent includes but is not limited to fumed silica, organic bentonite, hydrogenated castor oil, and polyethylene wax.

[0015] Further preferably, the coupling agent is a titanate coupling agent or a silane coupling agent.

[0018] A method for preparing a resin fabric composition comprises the following steps:

[0019] (1) Under room temperature, accurately weigh 100 parts of resin, 60-150 parts of functional filler, 5-20 parts of coupling agent, and 1.5-10 parts of dye according to the mass ratio and put them into a planetary mixer. After stirring evenly, add 3-35 parts of resin hardener and 3-12 parts of rheological agent, stir evenly again, remove bubbles, and obtain resin slurry after passing the test;

[0020] (2) Fabric treatment;

[0021] (3) The resin slurry is printed on the fabric treated in step (2) through a printing process, demoulded, and cured to obtain a resin fabric composition.

[0022] It should be noted that the resin hardener and rheological agent need to be added after the other raw materials are evenly stirred. The main reason is to extend the applicability of the resin slurry. In addition, the rheological properties of the resin slurry are adjusted so that the slurry has good permeability and thixotropy.

[0023] As a further preference, the yield stress of the resin slurry in the above step (1) is (10~500) Pa; when the temperature is 30°C and the shear rate is 0.5s -1 When the viscosity of the resin slurry is (2.5~6.8)×10 6 mPa.s; when the shear rate is 10.5s -1 When the viscosity is (0.5~3.3)×10 5 mPa.s; after the resin slurry is cured at high temperature (the curing temperature of the resin slurry is (110~170)℃, and the curing time is (0.5~2) hours), the shear modulus is greater than 8MPa and the Shore hardness D is greater than 80 degrees.

[0024] During the test, the applicant found that the yield stress and viscosity of the resin slurry determine its ability to penetrate into the interior of the fabric, and ultimately determine the bonding strength between the resin and the fabric. If the yield stress is too large, the slurry will not be able to penetrate into the interior of the fabric at all, resulting in a decrease in the bonding strength between the resin and the fabric, and eventually causing it to fall off during use and lose its protective ability. If the yield stress is too small, the penetration ability of the resin slurry will increase, and the resin pattern will not be able to maintain its shape under the action of gravity. At the same time, if the gap between the resin pattern is small, the resin pattern will be bonded to the bottom of the fabric, causing the cured resin-fabric composition to form a whole, losing flexibility, softness and breathability.

[0025] Further preferably, the purpose of the fabric treatment in the above step (2) is to improve the adhesion between the resin slurry and the fabric; preferably, the fabric treatment method is to perform corona discharge treatment, and the treated fabric is used as soon as possible to ensure good adhesion.

[0026] Further preferably, the printing process described in the above step (3) is a steel screen printing process, and the thickness of the steel screen is (0.1~5) mm; the steel screen printing pattern is preferably one or more polygons (such as triangles, quadrilaterals, pentagons, hexagons, etc.), one or more circles, or an appropriate combination of any one or more of them.

[0027] Further preferably, the thickness of the steel mesh is (0.15~3) mm; the gap width between the steel mesh printed patterns is (0.02~3.5) mm; when the printed pattern is a polygon, the diameter of its circumscribed circle is (1~15) mm; when the printed pattern is a circle, its diameter is (2~20) mm.

[0028] Further preferably, the gap width between the printed patterns is (0.05~3.0) mm, when the printed pattern is a polygon, the diameter of its circumscribed circle is (1.8~13.5) mm; when the printed pattern is a circle, its diameter is (2.5~18) mm.

[0029] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages.

[0030] 1. Using the steel screen printing process and a specific steel screen printing plate pattern arrangement design, the resin slurry is effectively printed on the chemical fiber textile fabric or chemical fiber and cotton fiber blended fabric treated with the dilatant fluid. The resin fabric composition undergoes a high-temperature in-situ curing reaction to form a soft and hard resin fabric. The resin fabric composition has excellent flexibility and mechanical properties.

[0031] 2. After high-temperature curing, the resin slurry forms a hard resin sheet with high mechanical strength, puncture resistance, cut resistance, high temperature resistance, friction resistance, anti-icing, fire resistance, mildew resistance, and antibacterial properties. Furthermore, the clever spacing between the resin sheets gives the resin fabric composition excellent flexibility and breathability, significantly improving wearer comfort. The hydrophobicity of the resin sheets prevents water from penetrating, keeping the surface of the resin fabric composition clean and dry, while also being stain-resistant.

[0032] 3. The pattern of the resin sheet is obtained by designing the steel screen printing plate, and the thickness of the resin sheet is the thickness of the steel screen printing plate; the geometry, thickness, color, size and fabric type of the resin sheet can be adjusted as needed or customized according to the application.

[0033] 4. The cured resin sheet is extremely hard and can resist the impact and puncture of sharp objects. When multiple layers of resin fabric are stacked together, that is, the resin sheets are overlapped up and down, it can not only effectively resist the puncture and impact of sharp objects, but also greatly increase the tear resistance, especially it can effectively protect against needle punctures.

[0034] 5. The resin sheet has a certain thickness, and the pattern can be designed in a nonlinear arrangement. The high mechanical strength of the resin sheet can effectively block the movement of the blade, thereby achieving the purpose of cutting resistance. After the resin fabric is stacked in multiple layers, its mechanical properties meet the highest level of protection requirements of European EN388 and Chinese GB 28881 standards.

[0035] 6. The resin slurry preparation method of the present invention is simple, the steel screen printing process is mature, the initial investment is small, the rate of return is high, and it is suitable for large-scale industrial production.

[0036] 7. The resin fabric composite material of the present invention can be widely used in various industries, such as mechanical processing, construction engineering, mining and metallurgy, outdoor equipment, military equipment, automobile manufacturing, petrochemical industry, glass manufacturing, firefighting equipment, etc. More specifically, for example, it can be used as outer fabrics for protective clothing for various outdoor sports, special foot protection fabrics such as mountaineering boots and special work boots, special industrial protective footwear fabrics, and military and police training protective footwear fabrics.
