Description

Technical Field

[0001] This invention relates to the field of wood building material protection and on-site rapid anti-corrosion and moisture-proof construction technology, and in particular to a moisture-proof on-site treatment technology for door frames and door frame moldings. Background Technology

[0002] In building interior decoration projects, door frames and door trim are core components of door and window decoration. Currently, most door frames and trims on the market are made of wood materials such as solid wood panels, engineered wood panels, and MDF. Wood naturally has a porous fibrous structure with numerous micropores, giving it strong moisture absorption and permeability properties. During long-term use, it is highly susceptible to environmental humidity and ground moisture. The lower end of the door frame and trim, which is in direct contact with the ground, is the weakest point of the entire component, most vulnerable to moisture. Condensation from the ground, capillary moisture, moisture from bathrooms and kitchens, and humid indoor air continuously penetrate the wood, causing a series of quality problems.

[0003] In current renovation construction, dampness-induced defects at the bottom of door frames and door trim are extremely common. These defects manifest as mold and blackening at the ends, swelling and warping of the wood, bulging and cracking, fiber rot, and insect infestation. This not only severely damages the aesthetics of the interior decoration and reduces the overall quality of the renovation, but also significantly shortens the lifespan of door frames and trim. Most wooden door frames show severe dampness damage after only 2-3 years, requiring frequent repairs and replacements, increasing maintenance costs for users. Especially in humid southern regions, low-rise residential buildings, ground-floor apartments without a raised floor, and near doorways around kitchens and bathrooms, the incidence of dampness and mold at the bottom of door frames is as high as 90%, a long-standing and difficult-to-cure problem in the interior decoration industry.

[0004] Currently, the moisture-proofing processes for door frames and door frame moldings in the industry are relatively traditional, with three main methods, all of which have obvious drawbacks: The first method is to apply a paint coating for moisture protection, which involves applying a clear varnish or moisture-proof paint to the bottom of the door frame to form a protective layer. This method is simple to operate, but the paint film only adheres to the surface of the wood and cannot penetrate into the internal pores of the wood. It only provides surface waterproofing and cannot prevent moisture from penetrating through the internal pores of the wood. At the same time, the paint cures slowly, requiring more than 24 hours for a single coat to dry, and multiple coats can take up to 3-5 days, seriously delaying the construction progress. Furthermore, the paint film has low hardness and poor toughness, making it prone to cracking, peeling, and flaking later on. The protective effect is short-lived and extremely poor.

[0005] The second method involves applying waterproof adhesive or silicone sealant to seal the moisture-proof layer, achieving moisture protection by sealing the gaps at the bottom of the door frame. However, this method only seals external gaps and cannot address the wood's own moisture absorption problem; ground moisture can still penetrate upwards through the wood's internal fibers. Furthermore, the adhesive is prone to aging, yellowing, and cracking, has poor adhesion, and is susceptible to mold growth in the gaps. Additionally, the adhesive has a long curing time, resulting in low on-site construction efficiency and limited applicability.

[0006] The third method involves pre-treatment by impregnation and drying at the factory, providing overall moisture protection before the door frame leaves the factory. This method has significant limitations in terms of on-site adaptability. During transportation and installation, the bottom of the door frame is easily damaged by cutting, grinding, and impacts, destroying the original protective layer. Freshly cut surfaces on-site have no moisture protection and will still quickly absorb moisture and mold. Furthermore, the factory pretreatment process is complex, requiring specialized equipment and high-temperature drying lines, resulting in high costs and long cycles. It cannot meet the needs of secondary moisture protection after temporary repairs at the construction site.

[0007] In addition, some existing new wood moisture-proofing technologies suffer from problems such as bulky equipment, complex operation, high professional requirements, and high construction costs. Ordinary renovation workers find them difficult to quickly master, and they cannot meet the lightweight, efficient, and immediate construction needs of on-site projects. In summary, the industry currently lacks a treatment process that is simple to operate, cures quickly, provides long-lasting protection, is suitable for on-site construction, and can completely solve the problem of moisture and mold growth at the bottom of door frames and moldings.

[0008] Based on the many shortcomings of existing technologies, this invention combines the unique physical waterproof and moisture-proof properties of paraffin wax to develop a moisture-proof on-site treatment technology for door frames and door frame moldings. By using on-site constant temperature hot-melt paraffin wax for short-term immersion and penetration, double-layer moisture-proof protection is achieved inside and outside the wood, completely solving the problems of incomplete protection, low efficiency, and easy failure of traditional processes. Summary of the Invention

[0009] To achieve the above objectives, the present invention provides the following technical solution: a moisture-proof on-site treatment technology for door frames and door frame moldings, wherein, step 1: heating solid paraffin wax to a molten state and controlling the temperature of the wax liquid between 65°C and 75°C; Step 2: Cut the ends of the wooden door frame or door frame trim to be soaked flush, and clean them thoroughly to ensure they are dry and free of contamination; Step 3: Immerse the end to be soaked after step 2 into the molten paraffin liquid prepared in step 1, with an immersion depth of 1-5 cm and an immersion time of 2-5 seconds; Step 4: Remove the soaked components from the wax liquid, place them vertically, and allow the wax liquid on their surface to cool and solidify naturally to obtain waterproof and moisture-proof wooden components.

[0010] Preferably, the solid paraffin wax mentioned in step 1 is fully refined paraffin wax with a melting point range of 50℃-62℃.

[0011] Preferably, in step 3, the soaking time is 3 seconds, and the temperature of the wax liquid is stably controlled at 68℃-72℃.

[0012] Preferably, in step 3, the immersion depth is 2-3 cm.

[0013] Preferably, the wooden door frame is made of any one of medium-density fiberboard, plywood, or finger-jointed solid wood.

[0014] Preferably, in step S4, after natural cooling and solidification, there is no dripping or sticking, and the cured paraffin protective layer has strong adhesion and good sealing performance, allowing for direct installation of door frames, application of adhesive, and subsequent construction processes such as finishing.

[0015] A specialized heating device for on-site moisture-proof treatment processes includes a housing, a heating component, a temperature control component, a wax storage chamber, and a protective insulation shell. The wax storage chamber is located inside the housing, and the heating component is fixedly installed at the bottom of the wax storage chamber. The temperature control component is installed on the outer wall of the housing and is electrically connected to the heating component. The housing is covered with a protective insulation shell, and a cover plate is provided at the top of the housing.

[0016] Preferably, the heating component is a full-area flat heating plate, which is completely in contact with the bottom surface of the wax storage chamber. The temperature control and adjustment component includes a temperature sensor and a control button, and the temperature sensor probe extends into the interior of the wax storage chamber.

[0017] Preferably, the wax storage chamber is a stainless steel rectangular cavity, and the protective heat-insulating shell is made of heat-insulating and flame-retardant material.

[0018] Beneficial effects: Compared with existing technologies, the molten paraffin wax in this invention has excellent fluidity at high temperatures, allowing it to quickly penetrate the capillary pores and internal fiber gaps of the wood surface, forming a hydrophobic layer inside the wood while simultaneously forming a dense wax film on the surface. This achieves dual protection, both internally and externally, completely blocking the path of moisture intrusion. The protective effect is far superior to traditional surface coating processes. This invention features a short overall construction process and low operational threshold, requiring no professional qualifications, complex procedures, or drying equipment. A single soaking takes only 2-5 seconds, followed by natural cooling and setting within seconds, eliminating the need for days of standing and drying. Installation can proceed directly after processing, increasing construction efficiency by over 90% compared to traditional methods. This significantly optimizes the critical path of renovation, making it suitable for batch high-end renovations and expedited projects. This invention can immediately apply moisture-proof sealing to fresh cut surfaces after cutting, grinding, and trimming on the construction site, completely making up for the industry shortcomings of factory prefabrication processes, such as "failure upon cutting and inability to be reinforced twice". It can adapt to the personalized on-site construction needs of different house types, different ground elevations, and different door frame sizes, greatly improving the flexibility and adaptability of construction.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Example 1: Optimal Overall Process Example of the Invention This embodiment provides an optimal parameter matching on-site moisture-proof treatment process for door frames and door frame moldings, which is compatible with most common wooden door frame substrates for home and commercial decoration. The specific steps are as follows: Step 1: Constant Temperature Melting of Paraffin Wax and Equipment Preheating. Select fully refined industrial paraffin wax with a melting point of 50℃-62℃. Place the solid paraffin wax block into the wax storage chamber 2 of the dedicated heating equipment, close the top cover 4, and connect the equipment power. Set the target constant temperature to 70℃ using the side wall temperature control adjustment component. Start uniform heating with the bottom heating plate 5, and the temperature sensor 6 collects the temperature of the wax liquid in the chamber in real time. After the solid paraffin wax is completely melted, without lumps or stratification, and the temperature is stabilized in the 68℃-72℃ range, maintain the constant temperature for 1 minute to ensure uniform wax viscosity and optimal fluidity, guaranteeing uniform and stable subsequent penetration. 70℃ is the optimal critical temperature for this process. At this temperature, the wax viscosity is lowest and the penetration kinetic energy is strongest, allowing for rapid penetration into the micropores of the wood while avoiding excessively high temperatures that could lead to paraffin wax thermal aging and carbonization, and overheating damage to the wood surface. It also avoids the defects of low temperatures that result in high viscosity, shallow penetration, and incomplete sealing.

[0024] Step Two: Refined Pre-treatment of Ends at the Construction Site. At the construction site, precisely cut and trim the solid wood multi-layer board door frame and matching door trim according to the door opening dimensions and the finished floor level. The lower end to be soaked is flush-cut and lightly sanded to ensure a flat, vertical surface free of chips, burrs, and protrusions. Thoroughly clean the end surface and surrounding area of ​​sawdust and dust with a stiff brush, then wipe away oil, water stains, and loose dust with a dry, lint-free cloth to ensure the treated end surface is completely dry, clean, and free of loose impurities. This prevents impurities from hindering paraffin penetration and affecting the bonding strength of the protective layer.

[0025] Step 3: Precise Deep Short-Time Penetration Sealing. Hold the pre-treated door frame and door frame trim vertically and steadily, then vertically immerse the lower end into the constant-temperature wax liquid, controlling the immersion depth to 2-3 cm, completely covering the core area exposed to moisture. Let it soak for 3 seconds. Under this constant temperature and low viscosity condition, the high-temperature wax liquid quickly wets the surface of the wood and continuously penetrates into the internal fiber pores through capillary action, replacing the air inside the pores and achieving pore saturation. At the same time, a uniform wax coating layer is formed on the end face and sides, constructing a preliminary double-layer protective structure.

[0026] Step Four: Natural Cooling and Shaping for Immediate Construction. After soaking, remove the component vertically at a uniform speed and suspend it in the air for about 6 seconds. The wax on the end face rapidly exchanges heat with the room temperature air, cooling down quickly. The internally penetrating paraffin wax solidifies rapidly, filling the pores, while the surface wax cools to form a dense, smooth, continuous, and complete hydrophobic protective film. After shaping, there are no dripping wax drops or sticky wax accumulation on the end face, and the shape is uniform. The protective layer is firmly bonded and has excellent sealing properties. Subsequent processes such as door frame positioning and installation, fixing, bottom caulking, and seam sealing can be carried out directly without any standing curing time, truly achieving on-site processing and construction.

[0027] Example 2: Differentiated Adaptation Process for Multiple Substrates To adapt to the differences in pore structure, density, and moisture absorption characteristics of different wood substrates, this invention provides a differentiated parameter adaptation scheme to further improve the specificity and protective effect of moisture protection: For medium-density fiberboard (MDF) door frames: This substrate has fine pores, high porosity, and is extremely hygroscopic, making it highly susceptible to mold and blackening. The wax solution was set at a constant temperature of 72℃, an immersion depth of 3 cm, and a soaking time of 4 seconds. By increasing the temperature to reduce the wax viscosity, extending the immersion time, and deepening the treatment depth, the ultra-fine pores were fully filled and saturated, completely eliminating capillary moisture absorption channels.

[0028] For solid wood finger-jointed door frames: Solid wood substrates are dense, have few pores, and high structural stability. By setting the wax solution to a constant temperature of 68℃, an immersion depth of 2 cm, and an immersion time of 2 seconds, the work time is shortened, paraffin wax consumption is saved, and construction efficiency is improved while ensuring effective moisture protection.

[0029] For solid wood composite multilayer board door frames: the substrate has a uniform pore structure and a stable layered structure. Using standard optimal parameters: temperature 70℃, immersion depth 2.5 cm, and immersion time 3 seconds, optimal balance is achieved in penetration effect, molding quality, and construction efficiency.

[0030] Working principle: The equipment has a compact rectangular box structure. The main body is the equipment shell, and the internal integrated stainless steel wax storage chamber is corrosion-resistant, high temperature-resistant, not easily deformed, and has no metal precipitation. It is suitable for long-term constant temperature melting of paraffin wax.

[0031] The bottom of the wax storage chamber 2 is fully covered with a flat heating element, which adopts a surface-type uniform heating mode. Compared with the traditional point or strip heating structure, there are no dead corners in the heating. The temperature rise of the wax liquid in the chamber is consistent and the temperature is uniform. This effectively avoids the problems of local overheating and carbonization, and local unmelted agglomeration, ensuring the consistency of the process and the stability of protection for each immersion treatment.

[0032] The equipment has an embedded temperature control and adjustment component on its side wall, which includes a high-precision temperature sensor 6 and a physical control button 7. The sensor probe penetrates deep into the wax liquid to measure the temperature in real time. It has a fast response speed and high acquisition accuracy, and can achieve a wide temperature range of 40℃-100℃. It can accurately lock the constant temperature range of 65℃-75℃ required for the process, and supports constant temperature locking and parameter memory to adapt to the fine adjustment needs of construction parameters under different substrates and different ambient temperatures.

[0033] The equipment is encased in a heat-insulating, flame-retardant protective shell 3, which effectively isolates the internal high-temperature heat, preventing burns to construction workers. It also provides impact protection, dustproofing, wear resistance, and heat preservation, reducing heat loss from the cavity and lowering energy consumption. An openable cover 4 is installed at the top of the equipment. When closed during construction, it prevents sawdust and dust from falling into the wax liquid and causing contamination, while also slowing down the cooling rate and reducing the energy consumption of repeated heating.

[0034] The equipment is lightweight and can be moved by a single person, making it suitable for multi-point mobile operations and fragmented construction on the decoration site, completely breaking through the limitations of traditional large equipment that cannot enter the site or be repaired on-site. Controlled experiment verification To objectively verify the technical advantages of this invention, a 6-hour continuous control test was conducted in a high-humidity simulated environment at 25°C. The test groups were: a traditional paint application group and the process of this invention group. The door frames of the two processes were placed in water with an immersion depth of 0.5 cm. The test results are as follows: Traditional processes result in cracking, delamination, and deformation after 6 hours; however, the process of this invention shows no deformation or cracking after 6 hours, the wood remains dry and stable internally, and the moisture-proof effect is stable and reliable.

[0035] In the above process, the molten paraffin in this invention has good fluidity at high temperature, which can quickly penetrate into the capillary channels and internal fiber gaps of the wood surface, forming a hydrophobic layer inside the wood and a dense wax film on the surface, achieving dual protection from both inside and outside, completely blocking the path of moisture intrusion, and the protective effect is far superior to traditional surface coating processes.

It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
