Description

Garden rockery beneficial to cultivation of green plants and processing method thereof

The technical field is as follows:

the invention relates to the technical field of rockery processing, in particular to a garden rockery beneficial to cultivation of green plants and a processing method thereof.

Background art:

rockery is a mountain constructed with materials such as soil and stone for landscaping in a garden. The rockery has various landscaping functions, such as forming a main scene or a terrain skeleton of a garden, dividing and organizing garden space, arranging courtyards, revetments, slope protection and soil retaining, and arranging a natural flower bed. The landscape architecture can be combined with garden buildings, garden roads, fields and garden plants to form a scene rich in changes, so that artificial atmosphere is reduced, natural interests are added, and the garden buildings are converged into a landscape environment. Therefore, rockery is one of the characteristics of representing the natural landscape garden of china.

The development of modern garden rockery is different from that of garden rockery, and the trend of diversification and synthesis is presented. The classical rockery is limited to stone materials, construction technical conditions and the like, and has certain limitation in the creation aspect of landscape. But the development of modern construction technology and artificial stone materials gradually makes it possible to create changeable and rich mountain and stone landscapes. Especially for the creation of large-scale and large-volume stone mountains, the inspiration of creation can be absorbed from the natural landform morphological characteristics and combination characteristics. The material is cement, mortar, concrete, glass fiber reinforced plastic, organic resin and GRC (glass fiber cement with low alkalinity), so that the plastic stone is formed in modern gardens. The advantages of the plastic stone are that the shape is random and changeable, the size can be large or small, the color can be changed, the weight is light, the stone is saved, the plastic stone works with modern interest are saved, and the plastic stone is especially suitable for places with limited construction conditions or limited bearing conditions.

At present, the production amount of the industrial waste blast furnace expanded slag and fly ash is large, and if the industrial waste blast furnace expanded slag and fly ash are unreasonably utilized, the environment is seriously influenced. The invention provides a method for processing rockery by using expanded slag and fly ash as main materials, which aims to realize the application of blast furnace expanded slag and fly ash in the processing of rockery.

The invention content is as follows:

the technical problem to be solved by the invention is to provide a garden rockery beneficial to cultivation of green plants, and the rockery has the advantages of low-price and easily-obtained processing raw materials, low processing cost, excellent service performance and simple processing procedure operation.

The technical problem to be solved by the invention is realized by adopting the following technical scheme:

a garden rockery beneficial to cultivation of green plants is prepared by processing the following raw materials in parts by weight:

30-80 parts of blast furnace expansion slag, 10-50 parts of fly ash, 10-50 parts of portland cement, 5-20 parts of lignocellulose, 5-20 parts of asbestos wool, 1-10 parts of a cement additive, 1-10 parts of a binder, 1-10 parts of a lubricant and 100 parts of water.

The blast furnace expansion slag is crushed to reach the granularity of 60-100 meshes.

The fly ash is I-grade fly ash.

The binder is one of styrene-butadiene copolymer, ethylene-vinyl acetate copolymer and styrene-maleic anhydride copolymer.

The lubricant is one of talcum powder, sepiolite powder and vermiculite powder.

The cement admixture is one of hydrolyzed polymaleic anhydride and polyaspartic acid.

The polyaspartic acid is usually used as a water treatment agent, a corrosion inhibitor and a fertilizer synergist, and the application of the polyaspartic acid as a cement additive is not reported in the field, but the polyaspartic acid is used as the cement additive to improve the service performance of the prepared rockery.

All carboxyl groups in the structure of the selected polyaspartic acid are carboxyl groups instead of carboxylate, and if sodium salt or potassium salt of polyaspartic acid is used as a raw material, the carboxylate needs to be converted into carboxyl groups by acidification.

In order to further improve the toughness of the produced rockery and avoid the fracture phenomenon of the rockery when large and medium green plants are cultivated due to over-strong brittleness, the invention also carries out plastic composite modification treatment on the asbestos wool, and the specific technical scheme is as follows:

the asbestos wool is subjected to plastic composite modification, and the modification method comprises the following steps: firstly, heating polylactic acid to a melting point, then preserving heat and stirring, adding asbestos wool after reaching a complete melting state, uniformly mixing, then carrying out microwave treatment by using a microwave reactor, and naturally cooling to room temperature to prepare powder.

The mass ratio of the asbestos wool to the polylactic acid is 10: 0.5-2.

The microwave frequency of the microwave reactor is 2450MHz, and the microwave power is 700W.

The polylactic acid is selected as the modifier, so that the toughness of the rockery can be obviously enhanced, and the environmental protection property is improved because the polylactic acid has biodegradability.

The processing method of the rockery comprises the following operation steps:

(1) manufacturing a mold: the die comprises an outer die and an inner die, and the die is manufactured according to a set rockery structure;

(2) mixing materials: adding all the raw materials into a mixer, and uniformly mixing to obtain a rockery processing material;

(4) demolding: solidifying and molding the material under natural conditions, and separating the outer mold and the inner mold to obtain a rockery crude product;

(5) modification: and (4) performing surface finishing on the produced rockery crude product to obtain a rockery finished product.

In order to further improve the service performance of the rockery, the processing method can also adopt the following technical scheme:

the processing method of the rockery comprises the following operation steps:

(1) manufacturing a mold: the die comprises an outer die and an inner die, and the die is manufactured according to a set rockery structure;
