Advantages and disadvantages of various material tree guards, cast iron tree guards are easy to rust, easy to be stolen by criminals; wooden boards are light in weight, easy to move, easy to rot, and have low degree of soil protection; sand and stone are easy to lose
Resin tree guards are light, easy to construct, easy to design, the size can meet the needs of different customers, and the color can be adjusted. However, this kind of tree guard has low strength, is easy to age, and is easy to be brittle and damaged under the trample of pedestrians.

preparation example Construction
[0020] As shown in the figure, the preparation method of a kind of ecological type tree guard board according to the present invention, wherein, the main raw material of the tree guard board is waste rubber or waste plastic particles, polyurethane glue, etc.; the present invention is to combine particles, glue and The chemical fertilizers are fully mixed in proportion; the specific operation steps are as follows:
[0021] (1.1), the waste rubber or waste plastic particles: the waste rubber or waste plastics are ground, sieved, and sieved into particles with different volumes;
[0022] (1.2), the obtained granules are mixed with fertilizer (usually select urea) to obtain a solid mixture containing waste rubber, plastics and urea;
[0023] (1.3), then mix the solid mixture containing waste rubber, plastics and fertilizers with polyurethane glue, mix well and set aside;
[0024] (1.4), under the non-rainy day situation, fill (find) the tree hole of tree with the fine sand that p...
Embodiment 1
[0030] Example 1: Grind waste rubber or waste plastic, and sieve to obtain 5-7mm particles; mix the particles with fertilizer at a volume ratio of 6:1, then mix the solid mixture with polyurethane glue at a mass ratio of 7:1, and mix well For later use; in non-rainy days, use fine sand to level the tree pit, according to the area of the tree pit 4kg / m 2 Weigh the mixture, spread it on the surface of fine sand, smooth it evenly, let it stand, and dry it naturally for more than 24 hours to obtain a tree guard board with a thickness of about 5-6mm.
Embodiment 2
[0031] Example 2: Grind waste rubber or waste plastic, and sieve to obtain 7-9mm particles; mix the particles with fertilizer at a volume ratio of 8:1, then mix the solid mixture with polyurethane glue at a mass ratio of 5.5:1, and mix well For later use; in non-rainy days, use fine sand to level the tree pit, according to the area of the tree pit 20kg / m 2 Weigh the mixture, spread it on the surface of fine sand, smooth it evenly, let it stand, and dry it naturally for more than 24 hours to obtain a tree guard with a thickness of about 20mm.

Abstract
The invention discloses a preparation method of an ecological tree protection plate. The invention relates to the technical field of municipal facilities. The method comprises the following steps of: grinding waste rubber and plastic, sieving the ground waste rubber and plastic to obtain particles, and mixing the particles with fertilizers to obtain a solid mixture; mixing the solid mixture with polyurethane glue; and filling a tree pit with fine sand, weighing the mixture, laying the mixture on the surface of the fine sand, smoothing, standing, and drying for more than 24 hours to obtain the tree protection plate. Gluing substances such as waste rubber or plastic used as raw materials have the characteristics of low carbon, environment friendliness and the like. The filling material is formed by gluing waste rubber or plastic and has good flexibility. The ecological tree protection plate can adapt to uneven tree pit surfaces. The tree protection plate is constructed according to the sizes and shapes of tree pits and trees on site, and is particularly suitable for eccentric trees not in the centers of the tree pits. Besides, fertilizers beneficial to tree growth are mixed in the mixture, the fertilizers are clamped among rubber or plastic particles, during irrigation or raining, the fertilizers are slowly released into the roots of the trees along with rainwater, and the tree protection plate plays a role in controlled release of the fertilizers.
Description
technical field [0001] The invention relates to the technical field of municipal facilities, in particular to a preparation method of an ecological tree protection board. Background technique [0002] The scientific name of the tree guard is called the tree pool cover. Depending on the regional dialect, it is also called Shuweizi, Shugrizi, Shuchizizi, etc. The main body of the tree guard board product is made up of two or four boards, which are widely used in parks, street green belts and various places for green tree shelter. There are rainwater permeation holes on the cover board, which can keep the roots of trees in soil Loosen and absorb nutrients such as water to protect trees from water and soil erosion. The installation of tree guards in the tree pool can also make the tree pit (tree pool) parallel to the sidewalk, reduce the unsafe hidden danger of passers-by being tripped while walking, and at the same time improve the urban cultural taste and beautify the urban ...
