Description

一种杉木芯板三层实木复合地板的生产方法 One kind of fir core board three parquet production methods

技术领域 FIELD

本发明涉及一种实木复合地板的生产方法,特别是一种杉木芯板三层实木复合地板的生产方法。 The present invention relates to a method for the production of parquet, fir particular method of producing a three-layer parquet core plate.

背景技术 Background technique

目前的三层实木复合地板一般采用松木作为芯板。 The current three-layer parquet commonly used pine as a core board. 但由于松木的生长慢,成材生长周期较长,资源较为稀缺,价格偏高,对实木复合地板的原料供需矛盾加剧,从而导致地板生产企业的产品成本较高。 However, due to slow growth pine, finished a long growth cycle, resources are more scarce, prices high, increasing raw material supply and demand for wood flooring, flooring manufacturers resulting in higher product costs. 而杉木是一种速生材,生长快,成材生长周期较短,资源较丰富,价格低廉且柔韧性能尚好。 The fir is a fast-growing wood, fast growth, to become useful short growth cycle, abundant resources, low cost and flexible performance is still good. 用杉木做三层实木复合地板的芯板,可大大降低企业的生产成本, 使企业能够生产出更加低廉的产品,在产品的市场价格竞争中处于有利的地位。 Cedar wood parquet three core plate, can greatly reduce production costs, enabling enterprises to produce more affordable products in a favorable position in the product market price competition. 因此,近年来很多地板生产企业开始采用杉木替代松木作为芯板。 Therefore, in recent years many flooring manufacturers began to use fir pine as an alternative core board. 但杉木是一种软质材,密度低,材质的稳定性能差,在用杉木做三层实木复合地板的芯板时,经常会发生翘曲变形的现象且变形的比例较大,影响了产品的品质,增加了产品的不良率,影响了企业的经营业绩,同时在生产中也给后续加工增加了难度。 But fir is a soft material, low density, poor stability of materials, doing three parquet core board with fir, warpage phenomenon often occurs and the proportion of deformation, affecting the product quality, increase the defect rate of products, affecting business performance, while in production but also to the subsequent processing more difficult. 在企业的实际生产中,往往通过陈放素板使其含水率平衡来避免翘曲变形的发生。 In the actual production enterprises, often landscapes equilibrium moisture content element plate so as to avoid occurrence of warpage by.

为获得最佳生产工艺参数,申请人进行了大量的实验和研究,以下是相关资料: For optimal production process parameters, the applicants have done a lot of experiments and research, the following information is relevant:

一、 试验材料和方法 I. Test Materials and methods

1、 材料。 1, material. 底板:杨木(旋切材厚度2.5mm):芯板:杉木(锯切材厚度10.5 mm):面板:柞木或沙比利(锯切材厚度3.2ran)。 Bottom: Poplar (peeler thickness 2.5mm): Core: fir (sawing Thickness 10.5 mm): Panel: Sapele or oak wood (sawn timber thickness 3.2ran). 成品地板的期望厚度是15mm。 Desired thickness of the finished floor is 15mm. 采用冷压胶合制作成型。 Using cold glue molding production. 胶粘剂:上海太尔化工冷压胶P6153。 Adhesive: Shanghai is too cold caulking Seoul Chemical P6153.

2、 方法:分三次实验。 2. Methods: Experiments in three installments. (每次实验按照实验设计的表格和随机次序和相应的不同因素的不同水平搭配进行)。 (According to the table for each experiment and experimental design in random order and corresponding with different levels of different factors were).

第一次实验进行实验因素的确定,共选择13个因素进行筛选实验,以确定关键影响因素 The first experiment was conducted to determine the experimental factors, 13 factors were selected screening experiments to determine the key factors

第二次实验根据第一次的实验结果,找出可能的关键影响因素,作为此次的实验因素, 进行实验并对实验结果进行分析,确定因素的最佳水平组合。 According to the experimental results of the second test for the first time, to identify the key factors likely, as the experimental factors, experimental results of experiments and analyzes to determine the optimal level of a combination of factors.

第三次实验用确定的因素最佳水平组合进行小批量生产,验证实验结果。 The third experiment was conducted with a small volume of factors to determine the best combination of levels, the results of verification experiments.

二、 实验结果分析和讨论 Second, the experimental results and discussion

1、筛选实验:实验参数选择和实验结果以及方差分析处理结果见表1〜表3。 1, screening assays: selecting the experimental parameters and results of variance analysis and the results are shown in Table 1 ~ 3.

的影响因素。 Factor. 但由于实验是精度为m的筛选实验,分辨率很低,目的是过滤过多的不显著因素,在这一精度的实验中主效应和两因素的交互作用相互混淆。 However, due to the experimental accuracy of the screening test is m, the resolution is very low, the filter object is not a significant factor too, two main effects and interaction factors confused with each other at the accuracy of the experiment. 而在含水率这个主效应的对照列中,还有两个最有可能是主要因素的交互作用存在。 In this comparison the water content of the column main effects, most likely there are two major factors in the presence of interaction. 所以还不能完全确定地板的变形是由面板含水率这个唯一的因素所引起的,还有可能是由于两因素的交互作用的结果,所以对于最有可能的交互作用因素应在下一个实验测试中给予考虑。 So it can not fully determine the deformation of the floor by the moisture content of the panel only caused by factors, there may be as a result of the interaction of two factors, so for the interaction of factors most likely to be an experimental test given below consider. 根据实际经验,除面板含水率 According to practical experience, in addition to the moisture content of the panel

外还应当考虑的因素有:底板含水率、底板布胶量、预压时间、固化剂的添加量。 External factors should also be considered are: the amount of base added water content, the amount of glue floor, squeeze time, the curing agent. 2、析因实验: 2, factorial experiment:

在这个实验中,根据上述筛选实验的结果和最有可能影响的交互作用确定的实验因素 In this experiment, according to the results of the screening test and the most likely to affect the interaction of experimental factors determined

是:面板含水率、底板含水率、底板布胶量、预压时间、固化剂的添加量。 They are: added amount of moisture panel, bottom water content, the amount of glue floor, squeeze time, the curing agent. 实验参数选择和 Selection and experimental parameters

3、确认实验: 3, confirmation experiment:

为了对所做的实验正确性进行验证,申请人按照工艺进行小批量生产来进行测试,测试结果见表8、表9。 In order to test the correctness made to verify the applicant small batch process according to test results shown in Table 8, Table 9. <table>table see original document page 9</column></row> <table>2、 根据生产的实际情况和实验结果,最佳的参数配比条件是:面板含水率为11〜13%; <Table> table see original document page 9 </ column> </ row> <table> 2, according to the actual production and experimental results, the optimum ratio parameter conditions: Panel 11~13% water content;

底板含水率为8〜10%;芯板含水率为11〜13%;面板布胶量为180〜220g/ni气底板布胶量为260〜300g/m2;铺放时间为30分钟:固化剂的添加量为10〜15% (可以根据天气季节变化进行调整)。 The aqueous base was 8~10%; water content of the core plates 11~13%; the amount of glue to panel 180~220g / ni base gas is the amount of glue 260~300g / m2; laying time of 30 minutes: curing agent the addition amount of 10 ~ 15% (can be adjusted according to seasonal weather changes). 若作为地板变形参数调整时,可以根据具体情况适当调整铺放时间和冷压压力:冷压压力为13kg/cn)2;陈放平衡时间为7天。 If the parameter adjustment as the deformation of the floor, can be appropriately adjusted depending on the circumstances and the laying time cold pressure: cold pressure of 13kg / cn) 2; landscapes equilibration time is 7 days.

3、 采用相同的胶粘剂(上海太尔冷压胶:P6153),通过改变相关参数的设定可以使三层实木复合地板的变形程度和变形比率降低,并且其他理化性能指标也完全符合和超过国家标准。 3, using the same adhesive (Shanghai Blantyre cold caulking: P6153), can make the degree of deformation and deformation rate three parquet reduced by changing the set parameters, and other physical and chemical properties is also fully meet and exceed the national standard.

以批量生产来进行测试。 Mass production testing. 与现有技术相比,本发明通过对面板含水率、底板含水率、底板布胶量、底板布胶量和固化剂的填加量等工艺参数的确定,很好的解决了用杉木做三层实木复合地板芯板时存在的易翘曲变形的问题,使三层实木复合地板的变形程度和变形比率降低,并且其理化性能指标也完全符合和超过国家标准。 Compared with the prior art, the present invention is determined by the moisture content of the panel, the moisture content of the base plate, the base plate filling amount of the amount of glue, the base plate and the amount of glue hardener process parameters, a good solution to three cedar wood problems easily deformed warp core plate there is a layer parquet, and the degree of deformation of the deformed three parquet ratio is reduced, and also its physical and chemical properties in full compliance with national standards and over. 提高了产品的品质,具有较好的经济效益和社会效益。 Improve product quality, with good economic and social benefits.

本发明的经济效益及社会效益分析: Economic and social benefits of the present invention Analysis:

经济效益分析:以年产三层实木复合地板30万Ilf计算。 Economic Benefit Analysis: The annual three-layer parquet 300,000 Ilf calculations. 用松木和杉木的价格差是5元ITf The price difference with pine and fir is 5 yuan ITf

,采用杉木后则由于成本减少而使经济收益年增加30*5=150万元。 After using fir reduce costs due to the increase in economic benefits 30 * 5 = 150 million.

社会效益分析:每年用芯板的木材是30*0. 0105=0. 3万m〜如果原木到成品出材率以35%计,则每年的原木用材量是O. 3/35%=8570m3,因杉木是速生材,生长期较短。 Social analysis: annual wood core board 30 = 0 * 00 105 30 000 If m~ material to finished timber in the count rate of 35%, the annual amount of timber logs is O. 3/35% = 8570m3.. , due to fast-growing wood is fir, shorter growing season. 而松木的生长期较长,从国家的资源可持续利用的角度来看,意义是重大的,从而也可带动行业的用料观念的转化,节省国家的珍贵木材资源。 The pine longer growing season, from the perspective of sustainable use of national resources point of view, the significance is significant, which also can drive the concept of transforming materials industry, saving valuable timber resources of the country.
