Description

Technical Field

[0001] The present invention relates to the field of cloth, and in particular to a cloth-plastic composite material and a preparation method thereof. Background Art

[0002] A tent is a shed propped up on the ground to shelter from wind, rain and sunlight and for temporary living. A tent mainly consists of a support frame and a tent cloth covering the support frame.

[0003] Tent fabrics need to have functions such as waterproofing, airtightness, thermal insulation, UV protection, antibacterial and insect repellent. However, general natural fabrics or chemical synthetic fabrics cannot have multiple functions at the same time. Therefore, existing tent fabrics are usually coated with a waterproof layer, a heat-insulating layer, an UV protection layer, an insect-proof layer, etc. on the base fabric. By continuously adding coatings with specific functions, the functional diversity of the tent fabric is increased, thereby improving the quality of the tent fabric.

[0004] However, processing tent cloth by applying multiple coatings will make the process extremely complicated, and the compatibility between coatings must also be considered. Once the compatibility is poor, cracking, blistering, and other phenomena are likely to occur, resulting in a more complicated and difficult process for the tent cloth. Therefore, there is still room for improvement. Summary of the Invention

[0005] In order to make the production process of tent cloth more convenient and simpler, the present application provides a cloth-plastic composite material and a preparation method thereof.

[0006] In a first aspect, the present application provides a cloth-plastic composite material, which adopts the following technical solution:

[0007] A cloth-plastic composite material comprising a cloth layer and a plastic coating, wherein the plastic coating is coated on the surface of the cloth layer;

[0008] The plastic coating is made of a composite plastic coating, which includes the following components in parts by mass:

[0009] 1000 parts of solvent;

[0010] 95-105 parts of PVC resin;

[0011] 36-38 parts of modified alumina powder;

[0012] 1-2 parts antioxidant;

[0013] 3-5 parts of compound oil-soluble plant extract;

[0014] The composite oil-soluble plant extract is a compound of rosemary extract, Nitraria tangutorum seed oil and Abelmoschus truncatus oil;

[0015] The modification method of the modified alumina powder is as follows:

[0016] Adding alumina powder into the modified liquid and mixing evenly, filtering and drying to obtain modified alumina powder;

[0017] The modified liquid is a compound of deionized water, a silane coupling agent and a nonionic surfactant.

[0018] By adopting the above technical solution, by adding modified alumina powder to the PVC resin, the plastic coating has a better heat reflection effect and plays a better thermal insulation effect; by adding composite oil-soluble plant extracts to the PVC resin, the plastic coating has a better insect repellent and antibacterial effect, and the plastic coating has a better ultraviolet absorption effect. Combined with the waterproof and windproof effects of the PVC resin itself, the prepared cloth-plastic composite material only needs to be coated with a layer of plastic coating on the cloth layer to obtain the effects of waterproofing, air release, thermal insulation, ultraviolet protection, antibacterial and insect prevention. There is no need to carry out the construction of multiple layers of coatings, and there is no need to consider the compatibility between coatings. The production process steps of the cloth-plastic composite material are relatively simple and the process difficulty is relatively low.

[0019] A composite oil-soluble extract is formed by specifically selecting rosemary extract, Nitraria tangutorum seed oil, and Hibiscus tiliaceus oil for compounding. Through the effective ingredients in rosemary extract, Nitraria tangutorum seed oil, and Hibiscus tiliaceus oil, the composite oil-soluble extract can simultaneously exert the effects of repelling insects, inhibiting bacteria, and absorbing ultraviolet rays, without the need to add a variety of functional raw materials, making the processing technology relatively simple.

[0020] When rosemary extract, white thorn seed oil and hibiscus oil are combined with each other, the effect of absorbing ultraviolet rays is significantly improved, so that adding a small amount of composite oil-soluble extract to the plastic coating can have a very significant effect of absorbing ultraviolet rays. When it is made into tent cloth, it can block ultraviolet rays very well and have a good sun protection effect, effectively protecting people in the tent and reducing the damage to the skin of people in the tent from ultraviolet rays.

[0021] By compounding a silane coupling agent and a non-ionic surfactant to prepare a modified liquid, the surface of the alumina powder is modified, so that the modified alumina powder has better compatibility with PVC, can be better dispersed evenly in the PVC resin, and is not easy to agglomerate. In addition, the effective ingredients in the composite oil-soluble extract can be better adsorbed in the modified alumina powder, so that the composite oil-soluble extract is not easy to volatilize, thereby achieving a more lasting effect of repelling insects, inhibiting bacteria, and absorbing ultraviolet rays.

[0022] Preferably, the solvent is tetrahydrofuran.

[0023] By adopting the above technical solution and specifically selecting tetrahydrofuran, the solubility of the PVC resin and the composite oil-soluble extract in the solvent is increased, so that the composite oil-soluble extract can be better dispersed evenly in the PVC resin, thereby achieving better insect repellent, antibacterial and ultraviolet absorption effects.

[0024] Preferably, the mass ratio of the rosemary extract, Nitraria tangutorum seed oil and Abelmoschus truncatus oil is 5-6:1-2:7-8.

[0025] By adopting the above technical solution and specifically selecting the mass ratio of rosemary extract, Nitraria tangutorum seed oil, and hibiscus oil, the rosemary extract, Nitraria tangutorum seed oil, and hibiscus oil can produce a more significant ultraviolet absorption effect after being combined with each other, and the sun protection effect of the tent cloth made of the cloth-plastic composite material is better.

[0026] Preferably, in the modified liquid, the mass ratio of deionized water, silane coupling agent, and nonionic surfactant is 100:4-5:1-2.

[0027] By adopting the above technical solution and specifically selecting the mass ratio of the silane coupling agent and the non-ionic surfactant, the compatibility of the modified alumina powder with PVC is improved, and the effective ingredients in the composite oil-soluble extract can be better adsorbed in the modified alumina powder, making the composite oil-soluble extract less likely to volatilize and lose, and making the heat insulation and sun protection effects of the cloth-plastic composite material more lasting.

[0028] Preferably, the silane coupling agent is a compound of silane coupling agent KH580, silane coupling agent KH171 and silane coupling agent KH792.

[0029] By adopting the above technical solution and specifically selecting the compound of silane coupling agent KH580, silane coupling agent KH171 and silane coupling agent KH792, the compatibility of modified alumina powder with PVC is improved, thereby better reflecting infrared rays and achieving better heat insulation effect. The tent cloth made of the cloth-plastic composite material can effectively block external heat and has a good cooling effect.

[0030] Preferably, the mass ratio of the silane coupling agent KH580, the silane coupling agent KH171, and the silane coupling agent KH792 is 1-2:2-3:9-10.

[0031] By adopting the above technical solution and specifically selecting the mass ratio of silane coupling agent KH580, silane coupling agent KH171, and silane coupling agent KH792, the compatibility of the modified alumina powder with PVC is improved, and the alumina powder is dispersed more evenly and is not easy to agglomerate.

[0032] Preferably, the nonionic surfactant is a compound of AEO-9 and Triton X-100.

[0033] By adopting the above technical solution and specifically selecting the compound of AEO-9 and Triton X-100, the effect of the modified alumina powder is better, and the thermal insulation performance of the prepared cloth-plastic composite material is better.

[0034] Preferably, the mass ratio of AEO-9 to Triton X-100 is 5-6:2-3.

[0035] By adopting the above technical solution, by specifically selecting the mass ratio of AEO-9 and Triton X-100, and combining them with a special silane coupling agent, the active substances in the composite oil-soluble extract can be better absorbed, so that the cloth-plastic composite material can still maintain good insect repellent, antibacterial and ultraviolet absorption effects after multiple washings.

[0036] Preferably, the fabric layer is woven from cotton yarn.

[0037] By adopting the above technical solution, cotton yarn is selected through cutting to weave into a cloth layer, so that the cloth layer can better absorb the plastic coating, making it difficult for the cloth layer and the plastic coating to separate, and the quality of the obtained cloth-plastic composite material is better.

[0038] In a second aspect, the present application provides a method for preparing a cloth-plastic composite material, which adopts the following technical solution:

[0039] A method for preparing the above-mentioned cloth-plastic composite material is as follows:

[0040] After the cloth layer is leveled, the composite plastic coating is evenly coated on the surface of the cloth layer and allowed to dry naturally to obtain a cloth-plastic composite material.

[0041] By adopting the above technical solution, the prepared cloth-plastic composite material has only a two-layer structure, and only one layer of coating needs to be applied during production, which makes the production process very simple and the process difficulty is relatively low. In addition, the prepared cloth-plastic composite material has excellent waterproofing, air release, thermal insulation, UV protection, antibacterial and insect repellent effects, and has high economic value.

[0042] In summary, this application has the following beneficial effects:

[0043] 1. Because the present application adds modified alumina powder to the PVC resin, the plastic coating has a good heat reflection effect and plays a good thermal insulation effect; and by adding a composite oil-soluble plant extract to the PVC resin, the plastic coating has a good insect repellent and antibacterial effect, and the plastic coating has a good ultraviolet absorption effect. Combined with the waterproof and windproof effects of the PVC resin itself, the prepared cloth-plastic composite material only needs to be coated with a layer of plastic coating on the cloth layer to obtain waterproof, air-proof, thermal insulation, ultraviolet protection, antibacterial and insect-proof effects. There is no need to carry out the construction of multiple layers of coatings, and there is no need to consider the compatibility between coatings, so that the production process steps of the cloth-plastic composite material are relatively simple and the process difficulty is relatively low.

[0044] 2. In the present application, rosemary extract, white thorn seed oil, and hibiscus oil are preferably combined with each other to significantly improve the effect of absorbing ultraviolet rays, so that a small amount of composite oil-soluble extract added to the plastic coating can significantly absorb ultraviolet rays, so that when the tent cloth is made, it can block ultraviolet rays well and have a good sun protection effect, effectively protecting people in the tent and reducing the damage to the skin of people in the tent from ultraviolet rays.

[0045] 3. In the present application, it is preferred to prepare a modified liquid by compounding a silane coupling agent and a nonionic surfactant, so that the surface of the alumina powder is modified, so that the modified alumina powder has better compatibility with PVC, can be better dispersed evenly in the PVC resin, is not easy to agglomerate, and the effective ingredients in the composite oil-soluble extract can be better adsorbed in the modified alumina powder, so that the composite oil-soluble extract is not easy to volatilize, thereby achieving a more lasting insect repellent, antibacterial, and ultraviolet absorption effect.

It can be seen that the special compounding of the silane coupling agent and the non-ionic surfactant helps to improve the compatibility of the oil-soluble plant extract and the modified alumina powder, so that the oil-soluble plant extract can be better adsorbed on the surface of the modified alumina powder, thereby making the composite oil-soluble plant extract evenly dispersed in the PVC resin, better playing a synergistic role, and making the composite oil-soluble plant extract not easy to volatilize, so that the anti-ultraviolet performance of the cloth-plastic composite material remains at a higher level after long-term immersion.

[0175] The width of the inhibition zone in each example is significantly greater than that in Comparative Examples 1-3, indicating that the special combination of the composite oil-soluble plant extracts can play a synergistic role, thereby significantly improving the antibacterial performance. The width of the inhibition zone in each example is slightly greater than that in Comparative Examples 4-8, indicating that the special combination of the silane coupling agent and the nonionic surfactant helps improve the compatibility of the oil-soluble plant extract and the modified alumina powder, allowing the oil-soluble plant extract to be better adsorbed on the surface of the modified alumina powder, making the composite oil-soluble plant extract less likely to volatilize, thereby maintaining a higher level of antibacterial performance of the cloth-plastic composite material after long-term immersion.
