Description

Technical Field

[0001] This invention relates to the field of woven strips, and more specifically to a production process and application for mass-produced woven strips. Background Technology

[0002] Rattan weaving is a practical and handicraft craft made from the outer skin and core of palm-like rattan stems. It is loved for its ability to be woven into a wide variety of patterns, resulting in various rattan woven items, rattan chairs, and even a diverse range of rattan furniture, enjoying a thriving global market. However, due to the increasing scarcity of genuine rattan, a trend has emerged in the market where plastic rattan is gradually replacing it.

[0003] Currently, rattan weaving has developed rapidly, gaining popularity for its beautiful designs, strong artistic appeal, and durability. Furthermore, plastic rattan is widely used in furniture due to its affordability and comfort, such as woven rattan tables, chairs, and sofas. However, most rattan furniture sold on the market is hand-woven, resulting in high production costs and low efficiency. Patent CN104708793B discloses a secondary molding method for plastic woven rattan. This method involves melting plastic granules and then molding them in a primary mold to obtain semi-finished rattan that is not fully cured. The semi-finished rattan is then further immersed in a cooling tank in a secondary molding process to obtain the final, three-dimensional product. However, this method is not suitable for mass production using mechanized weaving. Summary of the Invention

[0004] To overcome the above problems, the present invention provides a production process and application for mass-produced woven strips.

[0005] A production process for mass-produced woven strips, characterized by comprising the following steps:

[0006] (1) Mix the raw materials according to the weight parts, react for 2-3 hours, extrude through a melt extruder, and obtain extruded sheets after cooling;

[0007] (2) Cut the sheet flat or punch holes to form several parallel plastic sheets or plastic sheets with several holes;

[0008] (3) The plastic sheet is woven using a warp and weft weaving method to obtain the initial woven sheet product;

[0009] (4) Cut the sheet woven product and seal the ends of the cut sheet woven product with plastic sheet by melting and bonding to obtain the woven product.

[0010] The sheet extruded in step (1) has a width of 60-100cm and a thickness of 1-1.5mm.

[0011] The cutting direction in step (2) is parallel to the extrusion direction of the plastic sheet in step (1), resulting in 120-180 parallel plastic sheets; the punching method is to punch parallel holes along the extrusion direction of the plastic sheet in step (1), resulting in a plastic sheet with several holes with a hole spacing of 3-6 mm and a hole diameter of 2-4 mm.

[0012] In step (4), the woven sheet material and the plastic sheet are bonded at 190-250℃. The bond is strong and no metal tools are needed for fixing, resulting in an aesthetically pleasing appearance.

[0013] In step (4), the edges of the plastic sheet can be sealed by melt bonding at the interface and the port. The sealing process is simple, the structure is strong, and the resulting woven products are more beautiful and elegant.

[0014] The woven strip preparation process of this invention can produce large-area continuous rattan fabrics. The strips can be cut to size according to actual application needs, and plastic sheets are used to melt-bond each edge of the cut rattan fabric to prevent the plastic strips from loosening. This mechanized process replaces the traditional manual weaving method, reducing production costs and increasing efficiency. This is because the production process of this invention allows rattan products to be prepared in advance according to the actual shape and size of the furniture frame, breaking through the traditional manual weaving and wrapping process on the furniture frame. Therefore, it enables large-scale production of rattan furniture with high efficiency.

[0015] As a preferred technical solution, the woven strip is a plastic strip, and the raw materials for preparing the plastic strip include, by weight: 30-50 parts of polyolefin, 20-40 parts of POE elastomer, 10-30 parts of polydimethylsiloxane, 5-10 parts of plasticizer, 3-5 parts of antioxidant, and 3-13 parts of filler.

[0016] As a preferred technical solution, the polyolefin is one of polyethylene, polypropylene, polyvinyl chloride, polystyrene, or acrylonitrile-butadiene-styrene copolymer.

[0017] Preferably, the polyolefin is one of polyethylene, polypropylene, and polyvinyl chloride.

[0018] More preferably, the polyethylene is a blend of high-density polyethylene and low-density polyethylene, with a weight ratio of 1:(1-3).

[0019] As a preferred technical solution, the POE elastomer is one of ethylene-butene POE elastomer, ethylene-hexene POE elastomer, and ethylene-octene POE elastomer.

[0020] Preferably, the POE elastomer is POE7467, purchased from Shanghai Bogu New Materials Co., Ltd.

[0021] In the system of this invention, the added POE elastomer and the filler in the system form a unique system, which synergistically enhances the elasticity and toughness of the product, and has strong weavability, enabling the weaving of various patterns.

[0022] As a preferred technical solution, the polydimethylsiloxane is one of the following: hydroxyl-terminated linear polydimethylsiloxane, vinyl polydimethylsiloxane, and fluorinated polyester polydimethylsiloxane.

[0023] Preferably, the polydimethylsiloxane is a hydroxyl-terminated linear polydimethylsiloxane, model JZH-203, purchased from Jiangsu Zhonghe Silicon-based New Materials Co., Ltd.

[0024] As a preferred technical solution, the plasticizer is one of aliphatic diester plasticizers, phthalate plasticizers, benzoate plasticizers, epoxy plasticizers and polyester plasticizers.

[0025] Preferably, the plasticizer is a phthalate plasticizer.

[0026] Preferably, the phthalate plasticizer is a compound of dimethyl phthalate and diethyl phthalate, with a weight ratio of 1:(0.5-1).

[0027] In this invention, the use of a compound of dimethyl phthalate and diethyl phthalate as the plasticizer improves the flow properties of the solution during processing, facilitating processing. The resulting plastic strips are suitable for subsequent weaving into large-area continuous rattan fabrics, making them ideal for furniture, handicrafts, and other products. This is likely because, at specific ratios, dimethyl phthalate and diethyl phthalate are interwoven into the polymer molecular chains, weakening the stress between the polymer chains, reducing the crystallinity of the polymer, and increasing its flowability. This increases the polymer's plasticity, making the resulting plastic strips suitable for subsequent weaving into large-area continuous rattan fabrics, thus adapting to mass production.

[0028] More preferably, the phthalate plasticizer is a compound of dimethyl phthalate and diethyl phthalate, with a weight ratio of 1:(0.5-0.8).

[0029] More preferably, the phthalate plasticizer is a compound of dimethyl phthalate and diethyl phthalate, with a weight ratio of 1:0.65.

[0030] As a preferred technical solution, the antioxidant is at least one of phenolic antioxidants, aromatic amine antioxidants, phosphite antioxidants, and sulfur-containing ester antioxidants.

[0031] Preferably, the antioxidant is a combination of phenolic antioxidants and phosphite antioxidants, with a weight ratio of 1:(0.1-0.3).

[0032] Preferably, the antioxidant is a mixture of phenolic antioxidants and phosphite antioxidants in a weight ratio of 1:0.2.

[0034] Preferably, the phosphite antioxidant is antioxidant 168.

[0035] As a preferred technical solution, the filler is one or a combination of several of the following: magnesium hydroxide, calcium hydrogen sulfate, kaolin, diatomaceous earth, talc, graphite, carbon black, alumina powder, glass powder, asbestos powder, mica powder, quartz powder, and carbon fiber.

[0036] Preferably, the filler is a compound of magnesium hydroxide, alumina powder and carbon fiber, with a weight ratio of 1:(1-3):(0.2-0.5).

[0037] Preferably, the filler is a compound of magnesium hydroxide, alumina powder and carbon fiber, with a weight ratio of 1:2:(0.2-0.4).

[0038] Preferably, the filler is a compound of magnesium hydroxide, alumina powder and carbon fiber, with a weight ratio of 1:2:0.3.

[0039] Preferably, the magnesium hydroxide is nano-magnesium hydroxide with a particle size of 50nm, model CY-MHT01, purchased from Hangzhou Jiupeng New Materials Co., Ltd.; the alumina powder is nano-alumina powder with a particle size of 20nm, model XZ-L690, purchased from Hefei Xiangzheng Chemical Technology Co., Ltd.; and the carbon fiber is nano-carbon fiber powder with a particle size of 50-200nm, model CNF07, purchased from Songhu Shenjian Technology (Dongguan) Co., Ltd.

[0040] In this invention, the filler used is a blend of magnesium hydroxide, alumina powder, and carbon fiber, all with nanoscale particle sizes. These three nanoscale fillers work synergistically, dispersing well within the system and forming a well-defined dispersion that fills the polymer molecular chains. This reduces costs while improving the tensile strength, elongation at break, and other mechanical properties of the prepared plastic strips. Furthermore, the addition of nanoscale magnesium hydroxide endows the prepared plastic film with both good mechanical properties and a certain degree of flame retardancy. When applied to furniture or other products, it imparts flame-retardant properties, helping to prevent rapid combustion and reducing the harm caused by fire.

[0041] Another aspect of the present invention provides an application of a production process for mass-producing woven strips, which can be applied to the preparation of furniture, decoration or handicraft products.

[0042] The present invention has the following beneficial effects: 1) The present invention can seal the edges of the plastic sheet at the interface and end by melt bonding. The sealing process is simple, the structure is strong, and the woven products are more beautiful and elegant; 2) The preparation process of the woven strips of the present invention can weave large-area continuous rattan woven products. The size can be cut according to the actual application. Plastic strips are melt-bonded on each edge of the cut rattan woven products to prevent the plastic strips in the rattan woven products from loosening. The mechanization replaces the traditional manual weaving mode, reducing production costs and improving production efficiency; 3) The plastic sheet prepared by this application has high weaving elasticity and high toughness, and can realize a variety of weaving patterns; 4) The addition of specific fillers to the system of the present invention can reduce costs and improve the tensile strength, elongation at break and other mechanical properties of the prepared plastic strips, while also possessing a certain flame retardant ability.
