Description

Environmentally friendly lightweight Bakelite phenolic structure made by recycling and reusing phenolic waste materials

This new model relates to the reuse of phenolic waste, especially an environmentally friendly lightweight bakelite phenolic structure made by recycling and reusing phenolic waste. It can effectively reuse phenolic waste, and at the same time reuse other types of fiber waste and porous materials (such as waste activated carbon or foamed lightweight materials) to achieve the goal of recycling.

From an environmental engineering perspective, waste is a misplaced resource. It is very difficult to recycle resources in an appropriate way and reproduce them into usable and usable products. Especially thermosetting plastic products. There are almost only two final disposal methods: burying and incineration. Numerous manufacturers expect that while selling phenolic boards, they can also recycle phenolic boards (commonly known as bakelite boards) after use. Because phenolic bakelite is a thermosetting engineering plastic. Its characteristic is that the incineration temperature is high, and its high calorific value can easily cause the destruction of the incinerator body, exceeding the designed calorific value of the incinerator. And it reduces the willingness of cleaners to collect such waste into most incinerators for final treatment.

Phenolic board (commonly known as bakelite board), raw materials are phenols and aldehydes. After polymerization, it is made into phenolic resin. It is formed by impregnating phenolic resin, drying and hot pressing with paper or cloth as a carrier. The thermosetting plastic. Phenolic materials (phenolic board or bakelite board) are widely used in the printed circuit board industry as a protection board for the upper and lower pads in the drilling and molding process. Pad The type of use of bakelite boards, after being mechanically drilled, still conforms to the original material characteristics, but the geometric three-dimensional shape is changed after the printed circuit board manufacturing process such as drilling and molding, and the material itself has not changed. Phenolic materials (phenolic board or bakelite) are also widely used in insulation and heat insulation industries.

Generally used after drilling, molding, or powder, edge material and other types of bakelite waste (or phenolic resin type waste), because the original geometric shape that can be used has been destroyed, it is used directly There is little benefit to reuse. In order to effectively increase the availability of the final stage, the above-mentioned bakelite waste material is crushed and ground to refine the powder to form bakelite powder. Because the original resin occupies most of the fiber holes under the microscopic view, the subsequent resin is directly added. , Whether it is pressed or not, its combination is very weak. It is easy to form giant cracks under slight force or even in the process of gluing, which directly restricts the way in which the end can be reused.

Since the above-mentioned products are prone to form cracks, holes, or insufficient strength when they are reshaped, obvious product defects such as cracks, holes, or insufficient strength, and the deforestation based on the demand of the global wood industry will reduce the carbon dioxide capture, so this new model hopes to propose a waste Phenolic waste (bakelite waste) can be reused to recycle the recycled phenolic engineering plastic waste, especially the waste phenolic board after drilling, such as bakelite, bakelite, and bakelite. At the same time, it is used in combination with other fiber boards discarded after drilling. A new type of material can be formed through a new and easy-to-use reuse method, which can obtain a variety of benefits, which is different from traditional incineration and burying. Final treatment of environmental engineering. In order to widely increase the characteristics of waste fiber recycling and reuse, and achieve the goal of circular economy and the concept of environmental sustainability.

Therefore, the purpose of the present invention is to solve the above-mentioned conventional technical problems. The present invention proposes an environmentally friendly light-weight Bakelite phenolic structure manufactured by recycling and reusing phenolic waste materials. Type waste (that is, bakelite waste), wood fiber materials (waste fiber is better) and porous materials (such as waste activated carbon or foamed lightweight materials) are appropriately crushed and ground to a specific particle size Then, use a specific powder mixing ratio to mix uniformly, supplemented by the addition of resin, use a specific resin mixing ratio, and make up the waste bakelite waste as the main raw material of the new product. It is easy to cause uneven distribution after adding new resin. , The structure is not strong, and the density is too high and the weight is too heavy. Among them, the porous material can reduce the density of the overall material, so the weight is lighter, and it has fireproof and waterproof functions. It can also avoid the insufficient strength of the product when the waste fiber is the main structure. Then, the traditional plastic material manufacturing method is used to produce the final environmentally friendly bakelite phenolic material.

In this case, the aforementioned phenolic waste (or bakelite waste), wood fiber materials and porous materials (such as waste activated carbon or foamed lightweight materials) can also be appropriately crushed and ground to a specific particle size. Later, in a specific mixing ratio, acid or alkali can be added to allow phenolic waste (or bakelite waste) to be further destroyed. After the original phenolic waste is eroded, the number of holes is increased and the effect of fiber defibration is increased. The aforementioned fiber materials and porous materials can be additionally added to improve the cracks caused by poor resin bonding and unevenness. After the mixing is uniform, new resin is added in a specific resin mixing ratio, and the traditional plastic material manufacturing process is continued to make an environmentally friendly bakelite phenolic material product.

The specific resin mixing ratio refers to the weight of phenolic waste (or bakelite waste) powder, wood fiber material (waste fiber is better) powder and porous material powder, the total weight of the three powders, and the weight of the newly added resin The weight ratio can be in the range of 0.01 to 0.99, but it is not completely limited to this range.

The addition of the resin can be fireproof resin, waterproof resin, and light weight. The resin It can also be phenolic resin, urea-formaldehyde resin, epoxy resin, acrylic resin and other resin types. It can also be a bridging agent. However, it is not limited to the aforementioned resins or bridging agent types or their mixtures. It can be solid resin or liquid resin. Among them, the aforementioned resin is preferably phenolic resin.

The traditional plastic material manufacturing process includes mixing the ground mixed and sieved powder with solid resin, or after the ground mixed sieved powder is soaked with liquid resin, phase separated, and dried, it can be supplemented with a mold But it is not limited, and then batch-type hot-pressing or cold-pressing, or continuous hot-pressing or cold-pressing. If it is hot or cold pressing process, the pressure may be in the range of 0.001kg / cm ² to 300kg / cm ^2. Either the material is injected by the injection machine, or the material is extruded by the extruder. Or foamed as a foaming material. It can be but not limited to the aforementioned plastic production process.

The environmentally-friendly bakelite phenolic material products include, but are not limited to, drilled lower backing boards, upper cover boards, desktop boards, cutting backing boards used in the printed circuit board industry and copper foil substrate industry processes, or include However, it is not limited to the general use of bakelite, such as fixtures, jigs, heat insulation materials, and insulation materials, but is used as a new type of environmentally friendly bakelite or environmentally friendly wood. It can also include, but is not limited to, panels that are used as decoration and construction, such as plywood, plywood, wood core board, chipboard, Meinair board, fiberboard, foam board, floor, etc.; or furniture board; or External wall insulation and other purposes are regarded as new phenolic bakelite materials or recycled wood or materials. Or recycled materials after molding through general plastic manufacturing processes such as molds, fixtures, injection, and extrusion. In addition, the characteristic of this recycled material is that it can be reproduced and recycled continuously through the above-mentioned process. This effectively reduces the environmental load and increases the life of incinerators and landfills.

In order to achieve the above objective, this new model proposes an environmentally friendly lightweight bakelite phenolic structure, which is a flat panel structure with a specific geometric shape, wherein the environmentally friendly lightweight bakelite phenolic structure is a thick flat plate with a fixed geometric shape. The shape is selected from various shapes of polygons such as rectangles, squares, circles, rhombuses, triangles, etc.; the environmentally friendly light-weight Bakelite phenolic structure is made by mixing waste phenolic polymer materials, wood fibers, porous materials and resins.

With regard to the structural composition of this case, and the effects and advantages that can be produced, in conjunction with the drawings, a detailed description of a preferred embodiment of this case is given as follows.

Please refer to Figure 1, which shows the manufacturing method of the environmentally friendly light-weight Bakelite phenolic structure manufactured by recycling and reusing phenolic waste materials of the present invention, including the following steps:

Step 100: The waste phenolic polymer material is crushed and powdered to form a powder. The particle size of the waste phenolic polymer material powder can be a particle size of 1 to 200 meshes through a sieve. Preferably, the particle size of the waste phenolic polymer material powder is fine powder particles that can pass through a sieve of 200 mesh or more. However, the present case does not limit the particle size of the waste phenolic polymer material powder to a specific range, and the particle size of the waste phenolic polymer material powder can also be a combination of the above-mentioned ranges in specific ratios.

Among them, the waste phenolic polymer material is bakelite waste, which can be taken from the phenolic top cover, bottom pad, desktop board used in the mechanical drilling process of the printed circuit board manufacturing industry, or used in the cutting process of the copper foil substrate industry The cutting protection pad. However, the waste phenolic polymer material is not limited to the source of the aforementioned phenolic waste material. It is mainly used for the recycling of phenolic polymer materials after industrial treatment.

Step 110: The wood fiber (that is, the waste wood pulp board material after the drilling process of the printed circuit board) is crushed and powdered to form a powder. The particle size of the wood fiber powder can be sieved Through the particle size of 1 to 200 mesh, preferably the particle size of the wood fiber powder is fine powder particles that can pass through a sieve of 200 mesh or more. However, the present case does not limit the particle size of the wood fiber powder to a specific range, and the particle size of the wood fiber powder can also be a combination of specific ratios in the above-mentioned ranges.

The wood fiber can be a backing board, discarded wood pulp board, environmental protection board, or other types of fiber board used in the mechanical drilling process of the printed circuit board manufacturing industry. The wood fiber can also be used in the decoration industry, construction industry, wood industry, and furniture industry, such as discarded plywood, plywood, wood core board, particle board, meinite board, fiberboard and other boards, but it is not limited to It is a waste source, it can also be a fresh fiber source, such as wood flour, sawdust, or agricultural waste, such as rice straw, bagasse. But it does not limit all the wood fiber sources mentioned above. A more appropriate source of wood fiber is waste wood pulp board or environmental protection board after mechanical drilling process, or fresh wood flour.

Step 120: Take porous material, such as waste activated carbon, or foamed light material (such as foamed phenolic board); crush and pulverize the porous material to form a powder . The particle size of the powder of the porous material can be a particle size of 1 to 200 meshes through a sieve. Preferably, the particle size of the powder of the porous material is a fine powder particle that can be passed through a sieve of 200 mesh or more. However, this case does not limit the particle size of the porous material powder to a specific range.

Step 130: Then mix the powder of the waste phenolic polymer material, the powder of the wood fiber and the powder of the porous material. The total weight of the three is set to 1, the weight ratio of the waste phenolic polymer material powder to the mixture is in the range of 0.01 to 0.99; the weight ratio of the wood fiber powder to the mixture is in the range of 0.01 to 0.99. But it is not limited to this range. For example, the three can be uniformly mixed with a homogenizer in an equal amount.

Step 140: Then add an appropriate amount of resin, and apply a homogenizer to the waste phenolic polymer material powder Finally, the wood fiber powder, the porous material powder and the resin are uniformly mixed. The resin is mainly used to bond the waste phenolic polymer material powder, the wood fiber powder, and the porous material powder. When the proportion of the resin is higher, the degree of adhesion is better, but the cost is higher, and the recycling rate of waste utilization is lower. In this case, the preferred resin is fireproof resin, waterproof resin, and light weight.

Among them, the resin can be solid or liquid resin, preferably solid. The resin can be phenolic resin, urea-formaldehyde resin, epoxy resin, acrylic resin and other resin types, or a mixture thereof. Among them, the resin is preferably a phenolic resin.

However, the above-mentioned production process of forming the mixture into the solid material is not intended to limit the scope of this case.

Generally, the density of the waste phenolic polymer material is about 1.4, and the density of the wood fiber is about 0.6 to 0.8. Therefore, if only waste phenolic polymer materials and wood fiber are used for synthesis, the density will be too high, so the overall weight is heavier, which is not suitable for industrial applications. The density of the porous material (such as waste activated carbon or foamed lightweight material) is between 0.1 and 0.6. Therefore, in this case, further adding porous materials can reduce the density of the entire material, so many applications can be achieved.

The solid material can be, for example, a flat plate material, which has a fixed geometric shape, such as a rectangle, a square, a circle, a rhombus, a triangle, and other polygons of various shapes.

The solid material. Generally, the pressure is in the range of 0.001 ^{kg/cm 2} to 300 kg/cm ² and the temperature is higher than room temperature. As for the longer the hot pressing time, the harder the solid material obtained.

In step 100, the waste phenolic polymer material can be immersed in an acid or alkaline solution after being crushed and powdered, so that the surface of the waste phenolic polymer material is corroded or cracked into finer powder. The purpose is to increase the coagulation force combined with the resin in the subsequent steps. The acidic or alkaline solution includes, but is not limited to, strong acid, strong base, weak acid, weak base and other aqueous solutions, and can be, but is not limited to, hydrochloric acid, sulfuric acid, hydrofluoric acid, nitric acid, aqua regia, aqueous sodium hydroxide, and potassium hydroxide. Acid-base aqueous solutions such as aqueous solutions, calcium hydroxide aqueous solutions, and magnesium hydroxide aqueous solutions. The weight concentration of the acidic or alkaline solution is in the range of 0.1% to 99% aqueous solution.

For example, the powder of the waste phenolic polymer material is immersed in an appropriate amount of strong alkali sodium hydroxide solution (concentration of 10%, w/w), and the strong alkali sodium hydroxide solution floods the powder surface of the waste phenolic polymer material to Perform surface destruction. After 2 days, the strong alkali sodium hydroxide solution was leaked out, and the waste phenolic polymer material powder was washed with water to a pH range of 7-9, and then dried at a temperature of 100°C.
