一种快速侧滑安装地板的生产方法 技术领域
本发明涉及地板技术领域，更具体的说是涉及一种快速侧滑安装地板的生产方法。
背景技术
人们对于家居装修要求愈发精益求精，要求集美观性与实用性于一体。地板作为家居装修的必备品更是行走在前沿，为人们的生活带来舒适。实木地板、原木地板、复合型地板、多层地板等近些年来各式各样的地板品类层出不穷，极大的丰富了家居装修市场。
实木地板是指木材经烘干、加工后形成的地面装饰材料，它具有花纹自然、脚感舒适、使用安全的特点，是卧室、客厅、书房等地面装修的高档材料。然而由于木材湿胀干缩的天然特性，传统的实木地板对使用环境和条件要求高，受潮或吸水后易膨胀变形，受热失水后易收缩变形、开裂，导致地板损坏，具有很大的局限性。
为了提升市场竞争力，满足消费者生活水平升级后对地板耐地热功能的高要求，通常对实木坯料采用高温碳化热处理或二次平衡，然后在木板的企口喷涂封边漆、底面喷涂油漆或涂植物油，并在企口和底面覆膜处理；或者采用底面喷涂油漆或涂植物油、企口蜡封后，进行底面覆膜处理，阻断木材表面与水接触或湿度较大的空气接触，或降低环境温、湿度变化对木材产生的不利影响，达到防潮和保湿的效果。然而，上述地板依然存在以下问题：热处理改变了木材的很多天然特性，物理性能变弱，木材颜色变深等。二次平衡处理，虽然保护了木材天然特性，但是仍存在以下问题：一是企口涂布的油漆不能完全覆盖木材表面，只能起到部分防潮和保湿作用；二是企口蜡封，蜡封后企口互拼时，蜡膜因移动和安装敲击破损脱落，影响效果。
公布号为CN106272850A的中国发明专利公开了一种实木地热地板的制造工 艺，通过在板体的侧面设置塑封边框，防潮效果好，但是，其塑胶锁扣均为漏边式结构，即塑胶锁扣成型后会直接暴露在板体周边，铺装后影响美感；
公告号为CN104441183B的中国发明专利公开了一种下藏式塑边木地板的生产工艺，其在板体上塑封的边框隐藏在板体之下，但是，在专利全文中，并没有公开地板胚料的处理过程、地板坯料的注塑过程、模具结构、工艺参数以及实现方法；同时，对于地板锁扣而言，由于其在使用时是需要相互拼装的，所以锁扣的精度尤为重要，而注塑过程中的相关参数就显得尤为关键；所以，不清楚其实如何实现。

3、注射头加温，分为四段温度，最上端为一段，其次二段，中间三段，下端射咀四段。一、二段为熔料阶段，三、四段混合、保温阶段，确保物料完全熔融，保证了物料溶质流动速率。
