A kind of moisture-proof simulated tree bark and preparation method thereof

Abstract

The invention relates to a moistureproof simulated tree bark and a manufacturing method thereof. The bark is prepared from an epoxy resin, polyaniline, carboxyl polysiloxane, heavy calcium carbonate powder, vapor-phase white carbon black, a paint color paste, glass fibers, a solidifying agent, a desiccant, dibutyl phthalate and a mixed solvent. The manufacturing method comprises the following steps: adding the epoxy resin into a reaction kettle, adding the mixed solvent to dissolve the epoxy resin, adding the polyaniline into the reaction kettle, mixing, stirring at high speed, reacting at 20-25 DEG C for 1 hour while controlling the reaction pH value at 1, and adding the carboxyl polysiloxane; continuing reacting at ambient temperature to 50 DEG C for 2-5 hours; and adding the dibutyl phthalate, heavy calcium carbonate powder, vapor-phase white carbon black, paint color paste, glass fibers, solidifying agent and desiccant, mixing and stirring uniformly, pouring the mixture into a preset bark mold, and carrying out micropressure standing to finally obtain the moistureproof simulated tree bark finished product. The simulated tree bark is flexible and safe, and has the advantages of favorable moisture resistance and high water resistance.

Description

technical field [0001] The invention relates to the field of imitation products, in particular to a moisture-proof simulated tree bark and a manufacturing method thereof. Background technique [0002] In recent years, with the rapid development of science and technology, modern facilities can be seen everywhere. In order to meet the social requirements for environmental protection and aesthetics, especially for tourist attractions, parks and other places with special requirements for landscape, People pay more and more attention to the facilities in these places, and hope that they can be close to nature and integrated with nature, so that tourists can feel that they are in a natural environment rather than an artificial environment. In the prior art, most of the landscape facilities in parks and scenic spots are made of concrete, and the outer layer is made of textures to simulate the shape of trees. Because it is relatively hard, the raised parts are easy to cause scratche...

AI Technical Summary

Problems solved by technology

Silicone artificial bark has the following defects: 1. Silicone products are very easy to age, and the service life is very short; 2. The physical properties of hard silicone bark are poor in thermal expansion and contraction, so it is easy to crack and deform; 3. Soft High-quality silicone bark is difficult to attach to pillars and walls, and as a material for covering pillars, it is very easy to be weathered and peeled off artificially; 4. Soft silicone bark has a strong odor; 5. Soft silicone is only suitable for regular The shape, irregular cylindrical or tubular objects, is completely unsuitable, and objects with small diameters are even more unsuitable; 6. The price is expensive and the cost cannot be controlled

[0009] The applicant found that the use of epoxy resin as the raw material of the resin-synthesized bark board has reduced costs, good flexibility, and small deformation shrinkage, but the disadvantages are that the water resistance is not strong and the moisture resistance is not good.
