A kind of anti-aging artificial tree bark and preparation method thereof

Abstract

The invention discloses an anti-aging simulation tree bark and a preparation method thereof. The bark is prepared from the following raw materials: epoxy resin, polyaniline, carboxyl polysiloxane, ground calcium carbonate, fumed silica, pigment printing paste, glass fiber, a curing agent, dibutyl phthalate, an anti-ultraviolet agent and a mixed solvent. The preparation method comprises the following steps: adding the epoxy resin into a reaction kettle; adding the mixed solvent and dissolving; adding the polyaniline and epoxy resin into the reaction kettle and mixing; stirring at a high speed; controlling the pH value of the reaction to 1 and the reaction temperature to 20-25 DEG C; after 1 hour of reaction, adding the carboxyl polysiloxane, and further reacting for 2-5 hours at room temperature-50 DEG C; adding the dibutyl phthalate, ground calcium carbonate, fumed silica, pigment printing paste, glass fiber, curing agent and anti-ultraviolet agent, mixing and stirring uniformly and pouring into a pre-placed bark mould; and performing micro-pressure standing to obtain a finished product of the anti-aging simulation tree bark. The simulation tree bark disclosed by the invention is soft and safe and has good anti-aging property.

Description

technical field [0001] The invention relates to the field of imitation products, in particular to an anti-aging artificial 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 scratches ...

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

Based on the defects of the above-mentioned silicone simulated bark, it shows that the silicone-based bark material is not suitable for customers to choose! Therefore, the second generation of artificial bark products "cement foam bark" and "resin synthetic bark board" have become a new trend of artificial bark

However, the construction process of "cement foam bark" is more complicated
