Description

一种聚烯烃木塑复合材料及其制备方法 WPC preparation and one kind of polyolefin

技术领域 FIELD

[0001] 本发明属于木塑复合材料及其制备技术领域,具体涉及一种聚烯烃木塑复合材料及其制备方法。 [0001] The present invention belongs to the WPC and preparation technical field, particularly relates to a polyolefin plastic composite material and its preparation method.

背景技术 Background technique

[0002] 众所周知,随着经济的快速发展和人们生活水平的提高,木材需求量越来越大,而树木的生长周期又很长,使得可利用的木材越来越少,因此寻找木材的替代品变得十分急迫。 [0002] As we all know, with the rapid economic development and people's living standards, demand for wood is growing, but the growth cycle of trees and very long, so that the wood can be used less and less, so look for alternative timber product has become very urgent.

[0003] 由于木塑复合材料是将木粉与热塑性塑料经高温混炼,通过挤出、模压等方式制成的一种资源循环的绿色环保新材料,其具有木材的可锯、可刨、可钉等优良的加工性能,是木材的良好替代品,因此其不仅被广泛用于建筑行业、家具、汽车、园林、市政工程等领域,且还对节约自然资源、保护生态环境,发展绿色经济,走可持续发展道路,实现了经济和环保的双重效益具有重大意义。 [0003] WPC is because wood flour and high temperature thermoplastics kneading green resource recycling new material by extrusion, molding, etc. made of wood with a sawing, planing, excellent processing performance can be nailed, is a good alternative to wood, so it is not only widely used in the construction industry, furniture, cars, gardens, municipal engineering, and also to conserve natural resources, protect the ecological environment, the development of green economy and take the road of sustainable development and achieve economic and environmental benefits of dual of great significance.

[0004] 现有可广泛用于木塑复合材料的塑料有回收聚乙烯、回收聚丙烯、回收聚乙烯醋酸乙烯酯等热塑性材料,而用于木塑复合材料的天然纤维不仅包括木粉,还包括废旧报纸、植物秸杆等,这些材料既可以降低木塑复合材料的成本,还能提高复合材料的物理机械性能比如硬度、拉伸性能等。 [0004] can be used in existing plastic WPC a recovery polyethylene, recycled polypropylene, polyethylene vinyl acetate recycled thermoplastic material and natural fibers for the composite material include not only wood flour, also including waste paper, straw and other plants, both these materials can reduce the cost of WPC, but also improve the mechanical properties of the composite such as hardness, tensile properties.

[0005] 木塑复合材料的加工工艺有挤出、注塑等,在挤出和注塑工艺中,由于天然纤维的添加量很大,通常超过50%,甚至高达65%(Michael Roth et.al.Journal of Analyticaland Applied Pyrolysis.2007, 79: 306 - 312.王乐生,等.新型建筑材料,2010 (7):86 - 88.),使得木塑复合材料在成型加工时,存在熔融聚合物分子间的摩擦和聚合物熔体与加工设备表面间的摩擦, 前者会增大聚合物的熔融流动粘度,降低其流动性,严重时会导致材料的过热、老化;后者则使聚合物熔体与加工设备及其他接触材料表面间发生粘附,随温度升高,摩擦系数显著增大。 [0005] WPC process has an extrusion, injection molding, extrusion and injection molding process, due to the large added amount of the natural fibers, usually more than 50%, even up to 65% (Michael Roth et.al. Journal of Analyticaland Applied Pyrolysis.2007, 79: 306 - 312. Wang Lesheng, new building materials, etc., 2010 (7): 86 - 88.), so that WPC during molding, molten polymer molecules exist between friction and friction between the surface of the polymer melt processing equipment, the former will increase the viscosity of the polymer melt flow, reducing its fluidity, can cause serious overheating of the material, aging; the latter polymer melt and processing equipment and other materials between the contact surface adhesion occurs, with increasing temperature, the coefficient of friction increases significantly. 这两个因素的共同作用会使木塑复合材料在高温挤出和注塑过程中易出现聚合物降解、木粉烧焦、制品表面质量差,甚至没法加工等问题。 Interaction of these two factors make WPC prone to a high temperature during the extrusion and injection molding of polymer degradation, charred wood, poor surface quality of the article, not even processing problems. 为了解决这些问题,现有技术采用的措施是在其中加入润滑剂或润滑体系。 To solve these problems, the measures adopted in the prior art, adding a lubricant or lubrication system. 诚然恰当的润滑剂或润滑体系不仅可以提高制品质量,还可以提高产量,降低产品的生产成本,但不恰当的润滑剂或润滑体系不仅达不到相应的效果,还会使材料的挤出过程不稳定,产品外观产生鲨鱼皮、边缘锯齿等缺陷,甚而使注塑变得困难、充模不完整、制品表面不光滑等缺陷。 Indeed appropriate lubricant or the lubrication system can not only improve the quality of products, but also can increase productivity, reduce production costs, but improper lubricant or lubricating system not only from a corresponding effect, but also the material during extrusion unstable, generating a shark skin appearance, defects such as jagged edges, even difficult to make the injection, incomplete filling, the article surface is not smooth like defects. 因此,选择合适的润滑配方就成为了木塑复合材料加工中成败与否的关键。 Therefore, choosing the right lubricant formulations has become a key wood-plastic composite materials processing in success or failure.

[0006]目前,在木塑复合材料中常用的润滑剂或润滑体系(唐伟家,丁建生,塑木复合材料润滑剂和偶联剂技术进展.世界塑料,2006,24 (11):78-83.)有硬脂酸钙,硬脂酸镁,硬脂酸,石蜡,聚酯蜡,聚丙烯蜡,双酰胺的脂肪酸酯,季戊四醇的脂肪酸酯,甘油的脂肪酸酯及其混合物等,以及硬脂酸锌和N,N'乙撑双硬脂酸酰胺(EBS)的混合物。 . [0006] At present, commonly used in wood composite materials lubricant or lubrication system (Tang Wei home, Ding Jiansheng, lubricants, coupling agents and technical progress WPC plastic world, 2006,24 (11): 78-83 .) has calcium stearate, magnesium stearate, stearic acid, paraffin wax, polyester wax, polypropylene wax, fatty acid esters, bis amides, fatty acid esters of pentaerythritol, fatty acid esters of glycerol and mixtures thereof, and a mixture of zinc stearate and N, N 'ethylene bis stearamide (EBS) is.

[0007] 但是人们在使用中发现硬脂酸锌-EBS润滑体系与使用了马来酸酐接枝聚烯烃相容剂的体系有冲突,导致不仅会大大地降低偶联效果,同时还会降低聚烯烃木塑复合材料的力学性能,如弯曲强度、弯曲模量等。 [0007] However, it was found that zinc stearate -EBS lubrication system and a system using maleic anhydride-grafted polyolefin compatibilizer is a conflict, resulting in not only greatly reduce the effect of coupling, in use, while also reducing the poly mechanical properties of WPC olefin, such as bending strength, flexural modulus, and the like. 为此,美国专利N0.7,731,880公开了以EBS单独作为木塑复合材料的润滑剂或用EBS与浮石、滑石粉复配作为木塑复合材料的复合润滑剂,虽然所获得的聚烯烃木塑复合材料的性能优于硬脂酸锌-EBS润滑系统,使弯曲性能和吸水性能都得到了改善,但是其弯曲强度仅提高了10%,吸水性能也只有百分之几的改善,改进效果极为有限。 To this end, U.S. Patent No. N0.7,731,880 discloses a lubricant EBS alone as a WPC or EBS pumice, talc complex composite lubricant as WPC, although the obtained polyethylene WPC properties superior olefin zinc stearate -EBS lubrication system for the water absorption and flexural properties are improved, but the bending strength increased by only 10%, to improve the water absorption only a few percent, improved effect is extremely limited.

[0025] 本发明与现有技术相比,具有以下优点: [0025] Compared with the prior art the present invention has the following advantages:

[0026] 1、由于本发明提供的聚烯烃木塑复合材料中含有不溶于水,又难溶于脂肪烃和芳香烃溶剂,且耐高温的季戊四醇四苯甲酸酯,该产品的酯键与植物纤维的羟基能产生很强的氢键作用,对植物纤维的浸润性能好,因而能促进植物纤维在聚烯烃树脂中的均匀分散,大大增加植物纤维的填充量,降低产品成本;另外由于润滑剂酯键能与植物纤维产生氢键作用,并且润滑剂的非极性烷基能与聚烯烃很好的相容,从而可以改善木粉与聚烯烃树脂的相容性,使得加工过程中,植物纤维能被聚烯烃树脂完全包覆,减少植物纤维带来的摩擦阻力,避免产品外观出现鲨鱼皮、边缘锯齿、充模不完整、制品表面不光滑等缺陷。 [0026] 1, since the polyolefin material of the present invention provides a plastic composite containing the water-insoluble, and poorly soluble in aliphatic hydrocarbons and aromatic hydrocarbon solvents, and high temperature pentaerythritol tetrabenzoate, the product is an ester linkage hydroxy plant fibers can produce strong hydrogen bonds, good wetting properties of plant fibers, which can promote plant fibers are uniformly dispersed in the polyolefin resin, greatly increasing the filling amount of the plant fiber, reduce product cost; Further since the lubricating agent capable of establishing hydrogen interactions ester linkage with plant fibers and non-polar groups of the lubricant can be well compatible with the polyolefin, thereby improving the compatibility of polyolefin resin and wood powder, so that during processing, plant fibers can be completely coated polyolefin resin, plant fibers reduce friction caused to prevent occurrence of sharkskin appearance, jagged edges, incomplete filling, the article surface is not smooth like defects.

[0027] 2、由于本发明还可在润滑性能良好的新型润滑剂一季戊四醇四苯甲酸酯基础上,搭配常规的润滑剂来组成复合润滑体系,因而不仅可获得更好的润滑效果,提高熔融挤出效率和制品产量,且分散效果好,明显改善了聚烯烃木塑复合材料的弯曲性能和吸水性能,可作为高档的聚烯烃木塑复合材料,替代木材在室内外装修、建筑业等领域广泛使用。 [0027] 2, since the present invention is also excellent in lubricating properties a new lubricant based on pentaerythritol benzoate, with the conventional lubricant lubricating composition of the composite system, and therefore not only for better lubricating effect, improved melt-extrusion products and production efficiency, and good dispersing effect and significantly improves the bending polyolefin WPC and water absorption properties, can be used as high-grade polyolefin plastic composite materials to replace wood in the indoor and outdoor decoration, building industry widely use.

[0028] 3、由于本发明采用季戊四醇四苯甲酸酯作为润滑剂所得的木塑复合材料的平衡扭矩较小,因而可以显著地降低体系的能耗,提高生产效率。 [0028] 3, since the present invention employs as pentaerythritol benzoate WPC balance torque resulting lubricant is small, it is possible to significantly reduce the energy consumption of the system, improve production efficiency.

[0029] 4、本发明制备方法简单,工艺成熟,能耗低,易于掌握推广。 [0029] 4. Preparation method of the present invention is simple and mature technology, low energy consumption, easy to grasp promotion.
