Description

Novel high-strength multi-performance rubber-clad sandwich plate and process

Technical field

The invention relates to the field of composite materials, in particular to a new type of high-strength and multi-performance rubber-clad sandwich plate and a process.

Background technique

At present, although there are many kinds of high-strength composite plates, due to the lack of scientific theoretical guidance, the composite plates produced are not perfect in structure. The technical solutions adopted are to unilaterally consider enhancing the lateral tensile force of the plate or unilaterally considering the longitudinal direction of the plate. Bearing pressure, in terms of pressure bearing, bending resistance, impact resistance, sound insulation, conductivity, flame retardant and other properties, can not meet people's increasing actual needs. In particular, there is still a lack of research on the combination of structure and function of composite plates. Based on the above defects, a better structure is needed, which perfectly combines the structure and functionality of composite plates, not only in pressure resistance, bending resistance, resistance Composite board with stronger impact, and with functions such as sound insulation, conductivity, flame retardancy, shielding, etc., is used to meet people's demand for higher quality board. In the invention I applied for previously, it was published (Announcement) on 2018.11.06. (Announcement) No. CN108749193A, because no functional body is added to the sheet material layer and the adhesive, and no reinforcing body is added to the middle adhesive of the sheet, the elastic layer in the sheet has poor strength and has no special function. It can only be called For high-strength boards, the overall performance of the board is still insufficient. At present, in various literatures, materials, and patent searches, it has not been found that at the same time, the compression resistance of the sheet material is improved, and the tensile strength of the sheet material is also improved, which is similar to the product of the present invention.

technical problem

It solves the problems of low longitudinal pressure and low transverse tensile strength of the existing sheet, easy destruction of the sheet, and single performance. It not only improves the compression resistance of the sheet, but also improves the tensile resistance of the sheet, and also strengthens the pressure resistance and bending resistance of the sheet. And structural properties such as impact resistance, while making the plate conductive, superconducting, semiconducting, magnetic, piezoelectric, damping, absorbing, transmitting, friction, shielding, flame retardant, heat-resistant, sound-absorbing, heat-insulating, removing One or more special properties of formaldehyde, benzene removal, antibacterial, anti-radiation, emitting far infrared rays, purifying air, activating water, releasing negative ions.

Technical solutions

The present invention is directed to the above technical problems, and provides a new type of high-strength multi-performance laminated sandwich panel. According to the world's exclusive discovery, the strength of adjacent cemented materials increases mutually, that is, the composite materials cemented together, when the strength of one material When it increases, because the material is bonded to the reinforcement in the other material, such as reinforcing fibers, whiskers, solid particles, etc., it will affect the force displacement of the other reinforcement, which will also increase the resistance of the other material. Pulling force, the tensile strength of the other material will also increase. When the other material is pressurized in the longitudinal direction, the molecular molecular displacement distance will be small, and the longitudinal pressure resistance will increase accordingly. The present invention uses the The reinforcement body and functional body are combined with the performance of the reinforcement body and the functional body in the adjacent materials and materials to create a new type of high-strength multi-performance sandwich panel. According to this theory, a new type of high-strength, multi-performance laminated sandwich panel is used. The triple-strength structure is strengthened by mixing within the material layer, colloidal strengthening outside the material layer, and adding a material layer outside the colloid. Adding more than one functional body and combination in different material layers makes the board have multiple properties. Because the adhesive and the rubber elastic layer formed after the reinforcement mesh is cured can greatly enhance the elasticity of the sheet, it can solve the shortcomings of the existing sheet, such as low strength, easy breakage, poor function, high production cost, and small adaptation range, and allow the sheet structure More perfect, enhance the structural properties such as pressure resistance, bending resistance, impact resistance, etc., while making the plate conductive, superconducting, semiconducting, magnetic, piezoelectric, damping, absorbing, transmitting, friction, shielding, resistance One or more special properties of combustion, heat resistance, sound absorption, heat insulation, formaldehyde removal, benzene removal, antibacterial, radiation resistance, far infrared radiation, air purification, activated water, and release of negative ions. Using the above principles, it can be extended to make three or more sandwich panels. Through the combination of different materials, reinforcements and reinforcement nets, it is possible to achieve a lower cost to produce a substitute for traditional boards. Using this structure, by selecting different materials to combine, you can make boards with different properties, which can be used for flooring.

Physical coating: the process of using polymer or resin to process the surface of the material to achieve the surface modification of the filler . 2. Chemical coating: It is a method that uses functional groups in organic molecules to chemically react with the surface of the filler to cover the surface of powder particles and modify the surface of the particles. 3. Precipitation reaction: It is the reaction of precipitation of inorganic compounds on the particle surface to form one or more coatings on the particle surface to improve the surface properties of the powder. 4.

Then curing: product curing is divided into two stages of hardening and curing: it usually takes 24h from gel to triangulation, at this time the curing degree is 50% to 70%, which can be demoulded, and cured under natural environmental conditions for 1 to 2 weeks. In order to make the product have mechanical strength, it is said to be mature, and its curing degree is above 85%. Heating can promote the aging process. Demoulding and trimming demoulding: demoulding should ensure that the product is not damaged. The demoulding methods are as follows: ① Ejection and demoulding: The ejection device is embedded in the mold, and the screw is rotated during ejection to eject the product. ② Pressure demolding: There is a compressed air or water inlet on the mold. When demolding, pressurized air or water (0.2MPa) is pressed between the mold and the product, and simultaneously beat with a wooden hammer and a rubber hammer to separate the product from the mold. The injection molding process is to spray two polyesters mixed with an initiator and an accelerator from both sides of the spray gun, and simultaneously spray the cut glass fiber roving from the center of the spray gun, so that it is evenly mixed with the resin and deposited on the mold. When it is deposited to a certain thickness, it is compacted with rollers to impregnate the fiber with resin, eliminate air bubbles, and solidify into a product. Resin Transfer Molding (RTM) is a closed-mold molding technology that is improved by hand lay-up molding. Belonging to this process category abroad are resin injection process and pressure injection process. The characteristics of RTM forming technology: ① can produce two-sided products; ② high forming efficiency, suitable for medium-sized FRP products production (less than 20,000 pieces / year); ③ RTM is closed mold operation, does not pollute the environment, and does not harm workers' health; ④ The reinforcing material can be laid in any direction, which makes it easy to lay down the reinforcing material according to the product's stress condition. ⑤ Less raw materials and energy consumption. Compression molding is the oldest and infinitely dynamic molding method in the production of composite materials. It is a method of adding a certain amount of premix or prepreg into a metal counter mold, and then curing it by heating and pressure. The vacuum diversion process is divided into two methods, dry method and wet method. The wet method is to lay a hand lay-up or spray-mold an uncured product, cover it with a vacuum bag film, the product is located between the film and the mold, seal the periphery, and apply a vacuum (0.07 MPa) to eliminate bubbles and volatiles in the product. The dry method is to place the reinforced glass fiber on the mold, seal the vacuum bag film with the periphery of the mold, and introduce the resin from the other end of the mold into the mold through the pipeline while vacuuming, soaking the reinforced glass fiber.

Step 3: Make a reinforced adhesive, add one or more of a reinforcement, a modified reinforcement, and a functional body to the adhesive, and stir well.
