Embodiment 1

[0015] After treating the wood with Cu-8C organic solvent preservatives with concentrations of 0.5% and 1.0% respectively, the A-type wooden window frame was made. The test results showed that:

[0016] (1) Anti-mold performance measured according to GB / T 18261-2000: when the agent concentration is 0.5wt%, the average mold damage value (D) is 0.11, the control effect (E) is 96.77%, the color-changing bacteria damage value (D) is 0.00, and the control effect is 0.00. Effectiveness 100%;

[0017] (2) Antiseptic properties measured according to LY / T 1283-2011: the toxicity limit for Coriolus versicolor is 1.4~2.0kg / m 3 , the toxicity limit to the yellow spore fungus is 1.5~1.8kg / m 3 , the anti-corrosion effect is very good;

[0018] (3) According to GB / T 18260-2000, the anti-termite performance is measured: when the concentration of the agent against termites is 1.0%, the degree of moth is 1.0%, the weight loss rate of treated wood is 2.5%, and the termite mortality rate is 97....

Embodiment 2

[0024] The wood was treated with ASDB flame retardant preservative with a concentration of 10% to make B-type wooden window frames. After testing, the results showed that:

[0025] (1) Flame retardant properties measured according to GB / T 2406.2-2009

[0026]

[0027] (2) According to LY / T 1283-2011, the anticorrosion performance was measured: the average loss rate of Poria decumbens was 0.45%, the average loss rate of Coriolus versicolor was 0.23%, and their toxicity limits were all below 1.0%;

[0028] (3) Insect-proof performance measured according to GB / T 18260-2000: against domestic termites, when the pesticide concentration is 1.0%, the failure rate of the treated wood is 3.8%, and the termite mortality rate is as high as 95.9%.

Embodiment 3

[0030] The C-shaped window frame made of high-temperature heat-treated modified wood has undergone functional tests, and the results show that:

[0031] (1) Measured according to GB / T 4739-1995: After treatment, the "brightness" of wood generally decreases, the "chromaticity index" increases, and the "color difference" increases;

[0032] (2) Measured according to GB / T 1933-2009: the density of treated wood generally decreases;

[0033] (3) Measured according to GB / T 1931-2009: the equilibrium moisture content is between 5.7 and 6.6%;

[0034] (4) Dimensional stability measured according to GB / T 1932-2009, GB / T 1934.1-2009, GB / T 1934.2-2009: After treatment, the hygroscopicity of wood is reduced by 5.8%, the water absorption is reduced by 22.5%, and the wet swelling is reduced by 54.0% %, relatively speaking, the dimensional stability is greatly improved;

[0035] (5) Measured according to GB / T 1939-2009: the average compressive strength of wood after treatment increases by ...

Abstract

The invention relates to an anticorrosion, flame-retardant, modified, multifunctional wood roof window frame, belonging to the wood door / window material and new material technical field. The Menglier roof window is obtained by technical improvement on a conventional product after many years of research by our company, and mainly comprises a window frame, a window sash frame, a control drawbar and a light-transmissive board material. The window frame is made of wood treated by soaking in a Cu-8C organic solvent corrosion inhibitor, wood treated by soaking in an ASDB flame-retardant corrosion inhibitor, or wood modified by high temperature thermal treatment. The inventive window frame can satisfy the air quality requirements, at the same time has anti-mildew, anti-corrosion, anti-insect and flame-retardant functions, greatly improves the service life and lowers manufacture and maintenance costs.

Description

technical field [0001] The invention relates to an anti-corrosion, flame-retardant and modified multifunctional wooden roof window frame, which belongs to the technical field of wooden door and window materials and new materials. Background technique [0002] Known roof windows, especially openable roof windows, include a window frame mounted on the roof structure, a sash frame hinged on the window frame, and a light-transmitting plate material is installed on the sash frame. In the production process, according to different usage occasions, some functional components are added to the roof window, or coating and other treatments are performed to endow the roof window with functions such as ventilation and drainage. However, such structural improvements cannot fully improve its durability and Practicality, its basic innovation should be placed on the materials used for roof window frames. After long-term exploration and research, the present invention provides a wooden mater...
