Description

Environmentally friendly bakelite phenolic structure made by recycling and reusing phenolic waste

This model relates to the reuse of phenolic waste, especially an environmentally friendly bakelite phenolic structure manufactured by recycling and reusing phenolic waste. It can effectively reuse phenolic waste materials and at the same time reuse other types of fiber waste materials to achieve the self-standard of recycling.

From an environmental engineering perspective, waste is a misplaced resource. It is very difficult to recycle resources in an appropriate way and make them into usable and usable products. Especially thermosetting plastic products. There are almost only two final disposal methods: burying and incineration. Numerous manufacturers hope 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, using paper or cloth as the carrier, impregnated with phenolic resin, drying, and hot pressing to form The thermosetting plastic. Phenolic materials (phenolic boards or bakelite boards) 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. The bakelite used for the backing board type actually still conforms to the original material characteristics after being mechanically drilled. 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, after drilling, molding, or powder, edge material and other types of bakelite waste (or phenolic resin type waste) after use, 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. , Regardless of 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 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 reduction of carbon dioxide capture due to the demand of the global wood industry due to the cutting of forest land, the 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 conjunction with other fiber boards discarded after drilling. A new type of material can be formed by a new and easy-to-use reuse method, which can obtain multiple 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.

After the resin, there will be defects caused by uneven distribution and weak structure. It can also avoid the insufficient strength of the product when the waste fiber is the main structure. Then, the traditional plastic material manufacturing process is used to make the final environmentally friendly bakelite phenolic material.

In this case, the aforementioned phenolic waste (or bakelite waste) and other fiber materials can also be appropriately crushed and ground to a specific particle size. Acid or alkali can be added in a specific mixing ratio to make phenolic waste (or bakelite waste). Bakelite waste) was further destroyed. After the original phenolic waste is eroded, the number of holes increases and the effect of defibrating is achieved. The aforementioned fiber 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 product.

The specific resin mixing ratio refers to the weight of phenolic waste (or bakelite waste) powder and fiber material (waste fiber is better) powder. The weight of the two powders is the sum of the weight of the newly added resin, which can be The range of 0.01 to 0.99, but not limited to this range.

The addition of the resin can 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 sieving powder and mixing solid resin, or the ground mixed sieving powder is soaked in liquid resin, phase separated, and dried, and can be supplemented with a mold But it is not limited, and then batch-type hot pressing or cold pressing molding, or continuous hot pressing or cold pressing molding. If it is a hot pressing or cold pressing process, the pressure can be 0.01kg/cm2 to 300kg/cm2 range. 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 But 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. 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 board for furniture; 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 process. This will effectively reduce the environmental load and increase the life of incinerators and landfills.

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

Please refer to Figure 1, which shows the manufacturing method of the environmentally friendly 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. Wherein, the particle size of the waste phenolic polymer material powder can be a particle size of 1 to 200 mesh 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, this 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. For example, the waste phenolic polymer material is screened through a 200-mesh screen, and its particle size accounts for 60% of the total waste phenolic polymer material powder; and the waste phenolic polymer material is screened with a mesh size of 100 to 200, and its particle size It accounts for 40% of the total waste phenolic polymer powder.

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 aforementioned phenolic type waste material source. 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 a particle size of 1 to 200 mesh through a sieve, and preferably the particle size of the wood fiber powder 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 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 ranges. For example, the wood fiber powder is screened through a 200-mesh screen, and its particle size accounts for 80% of the total waste phenolic polymer material powder; and the wood fiber powder is screened through a 100-200 mesh screen, and its particle size is It accounts for 20% of the total waste phenolic polymer powder.

Among them, the wood fiber can be used as a backing board in the mechanical drilling process of the printed circuit board manufacturing industry.

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: Then mix the waste phenolic polymer material powder with the wood fiber powder. The weight ratio of the mixing of the two can be in the range of 0.01 to 0.99 (that is, the range of the waste phenolic polymer material powder/the wood fiber powder is between 0.01 and 0.99), but is not completely limited to this range. For example, the powder of waste phenolic polymer material and the powder of wood fiber are uniformly mixed (1kg of waste phenolic polymer material and 1kg of wood fiber powder) in a homogenizer.

Step 130: Then add an appropriate amount of resin, and use a homogenizer to uniformly mix the waste phenolic polymer material powder, the wood fiber powder and the resin. The resin is mainly used to bond the waste phenolic polymer material powder and the wood fiber powder. When the ratio 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. For example, 1kg of waste phenolic polymer powder is mixed with 1kg of wood fiber powder and then 1kg of resin is added.

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 phenolic resin. When the resin is a phenolic resin, the molar ratio (F/P ratio) of formaldehyde to phenol in the phenolic resin is preferably in the range of 0.1:1 to 3.0:1.
