摘要

为解决薄型地采暖用实木地板因环境湿度变化而发生离缝、翘曲、开裂和起拱等尺寸稳定性不足的问题，以番龙眼（

Pometia pinnata

）为研究对象，采用230 °C、240 °C和250 °C加压热处理7 min的方法对其改性，并制备成薄型地采暖用实木地板，评价其线性湿胀率、抗胀率、漆膜性能

、耐湿和耐热尺寸稳定性。结果表明，随着处理温度的升高，试件平衡含水率和吸水率逐渐降低（P

0.05），且吸湿和吸水条件下的线性湿胀率逐渐减小和体积抗胀率逐渐增大（P

0.05），250 °C处理番龙眼木材的吸湿和吸水体积抗胀率分别为59.29%和33.69%，抗弯强度和弹性模量分别为111.45 MPa和11.58 GPa，分别较对照组降低了9.47%（p

0.05）和2.11%（p

0.05）。在230 °C、240 °C和250 °C条件下，地采暖用实木地板耐湿尺寸稳定性（长/宽度膨胀率）分别为0.02%/0.16%、0.02%/0.14%和0.01%/0.09%，耐热尺寸稳定性（长/宽度收缩率）分别为0.08%/0.34%、0.06%/0.34%和0.03%/0.21%，耐湿和耐热尺寸稳定性较对照组均显著提高（p

0.05）。导热效能均达到11 °C·h

-1

，尺寸稳定性和导热效能分别符合GB/T 35913-2018《地采暖用实木地板技术要求》和GB/T 41547-2022《地采暖用木质地板》对地采暖用实木地板的技术要求；同时，其漆膜附着力、硬度及耐磨性能均符合GB/T 15036-2018《实木地板第1部分：技术要求》中优等品的技术要求。

Abstract

To address the issue of insufficient dimensional stability in thin solid wood flooring for ground heating system

which can lead to problems such as seam separation

warping

cracking

and buckling due to changes in environmental humidity

this study focuses on

Pometia pinnata

wood. The research employs pressurized heat treatment methods at 230 °C

240 °C

and 250 °C to modify the wood

subsequently fabricating thin solid wood flooring for ground heating system. The linear swelling

anti-swelling efficiency

coating performance

wet-resistant

and heat-resistant dimensional stability are evaluated. The results indicated that with increasing treatment temperature

the equilibrium moisture content and water absorption of the specimens gradually decreased(P

0.05)

while the linear swelling under moisture and water absorption conditions decreased and the volumetric anti-swelling efficiency increased(P

0.05). For

Pometia pinnata

wood treated at 250 °C. the volumetric anti-swelling efficiency under moisture and water absorption were 59.29% and 33.69%

respectively. The modulus of rupture and modulus of elasticity were 111.45 MPa and 11.58 GPa

representing decreases of 9.47%(P

0.05) and 2.11% (p

0.05)relative to the control group. At 230 °C

240 °C

and 250 °C

the wet-resistant dimensional stability (length/width swelling) of the flooring was 0.02%/0.1

0.02%/0.14%

and 0.01%/0.09%

respectively. The heat-resistant dimensional stability (length/width shrinkage) was 0.08%/0.34%

0.06%/0.34%

and 0.03%/0.21%

respectively. Both wet-resistant and heat-resistant dimensional stability were significantly improved compared to the control (P

0.05). The thermal conductivity efficiency reached 11 °C·h⁻¹ in all groups. The dimensional stability and thermal conductivity met the requirements of GB/T 35913-2018 "Technical requirements of solid wood flooring for ground with heating system" and GB/T 41547-2022 "Wood-based flooring for underfloor heating" for solid wood flooring for ground with heating system. In addition

the coating adhesion

hardness

and wear resistance met the premium-grade requirements of GB/T 15036-2018 "Solid wood flooring-Part 1: Technical requirements".
