Description

Epoxy infiltration closed periphery prefabricated pressure groove composite board

Technical Field

The utility model relates to a fields such as architectural decoration material technique, specific epoxy infiltration seals prefabricated indent composite sheet all around that says so.

Background

Building decoration is a short for building decoration project. The architectural decoration is a variety of processes for the interior and exterior surfaces and spaces of buildings by using decorative materials or ornaments in order to protect the main structure of the buildings, improve the physical properties and use functions of the buildings and beautify the buildings. Architectural decoration is an indispensable part of people's life. Is an important friend of human taste life and taste life. As the life rhythm of modern people is accelerated, the nerves of people are nervous, and people want to really relax after work. At this time, the house is required to be warm. Therefore, when decorating in the home, attention must be paid to warmth.

The architectural decoration industry has become one of three major shoring industries in the construction industry, and is a labor intensive industry. The architectural decoration industry is a sunrise industry which grows rapidly along with the gradual rise of real estate hot tides. In recent years, with the rapid growth of the Chinese economy and the vigorous development of the related industries, the architectural decoration industry increasingly shows its great development potential, and the market growth space is increasing at a rate of about 20% per year on average.

The Chinese building decoration material industry is also rapidly developed along with the development of real estate and building decoration industry. China has become a large producing, consuming and exporting country of decorative materials in the world. Materials dominate products not only in the first place in the world in total for many years, but the per-capita consumption index has approached and exceeded the world's advanced level. The development of the architectural decoration industry is accelerated, the overall operation quality of the industry is improved, the method is an important content for comprehensively building a well-being society, the computer technology and the network technology are fully utilized, the informatization level of enterprise management, design and construction is improved, and the method is an important way for realizing the cross-over development of the architectural decoration industry.

The decorating material (building decorating material) is used mainly in decorating inner and outer walls and making inner wall of building, and has partial use function based on decoration. Also known as finishing materials and facing materials. Mainly grass, wood, stone, sand, brick, tile, cement, gypsum, asbestos, lime, glass, mosaic, soft porcelain, ceramic, paint coating, paper, ecological wood, metal, plastic, fabric and the like, and various composite products. The main applications are divided into 3 categories:

the ground decoration material:

the cement mortar floor has good wear resistance and the widest use, but has the defects of poor sound insulation, no elasticity, large heat conductivity and the like;

the marble floor has clear and beautiful texture and is commonly used in public activity places such as high-grade hotels and the like;

the terrazzo floor has good wear resistance, is bright and beautiful, and can be made into various floriation patterns by a foundation make-up machine;

the wood floor is elastic, has small heat conductivity, gives people warm and soft feeling, is durable because the parquet hardwood floor is laid into matting and herringbone patterns, and is mainly used in gymnasiums, rehearsal halls, stages and banquet halls.

The novel ground decorative materials comprise wood fiber floors, plastic floors, soft porcelain external wall tiles, ceramic mosaic tiles and the like. The mosaic ceramic tile is hard, acid resistant, alkali resistant, wear resistant, water impermeable and easy to clean, and may be used as floor tile and inner and outer wall facing.

Interior wall decorative materials:

the traditional method is to brush lime water or wall whitewash, but the method is easy to pollute and cannot be scrubbed by a wet method, and is mostly used for common buildings. The higher-grade multi-purpose flat-gloss mixed paint for buildings has rich color and luster and is not easy to pollute, but the volatile amount of the doped organic solvent is large, so the mixed organic solvent pollutes the atmosphere and affects the health of constructors. Paper pasting indoor walls and ceilings has a long history, but has been replaced by plastic wallpaper and fiberglass wall covering. The gypsum board has the characteristics of fire prevention, sound insulation, heat insulation, light weight, high strength, convenient construction and the like, and is mainly used for wall surfaces and flat tops; when the plate is flattopped, holes with various patterns can be punched to improve sound absorption and decoration effects. The calcium plastic board has good decorative effect, can preserve heat and insulate sound, and is a multifunctional board. The use of marble and granite slabs for decorating high-grade hotels and apartments is increasing.

The exterior wall decoration material:

the common cement mortar, chopped artificial stone, wet brushed stone, glazed tile, soft porcelain external wall tile, ceramic mosaic tile, paint, white cement paste and the like. New exterior wall finishing materials such as paints, polymer cement mortar, asbestos cement sheets, glass curtain walls, aluminum alloy products, etc. are being used in some projects.

The novel decorative material is as follows:

with the continuous development of scientific technology and the continuous improvement of the living standard of human beings, the architectural decoration develops towards a novel decorative material which is environment-friendly, multifunctional, high in strength, light in weight, finished, standardized in installation and intelligent in control. The latest decorative material greatly reduces the labor intensity of production workers. Thoroughly changed the former a great deal of drawbacks that found the mould, the shaping was pour to the flat mould. If the usage amount of the die is large, the turnover rate is low, electric heating or steam heating is needed, and the product type is single; sound insulation and heat preservation effects can not meet various market requirements. The novel decorative material has the characteristics that: the raw materials for production are wide in source and have no local limitation. The production process is simple, the automation degree of equipment is high, the labor intensity is low, the assembly line operation is realized, and the production process has no noise and no three-waste emission. The production energy consumption is low, high temperature and high pressure are not needed, and the heat is released by chemical reaction to meet the requirements of the production process.

The novel decorative material is required by the development of the times, and the latest decorative material is energy-saving and environment-friendly: the production process does not need high temperature and high pressure, the product is nontoxic, harmless, pollution-free and radioactivity-free, belongs to a green, environment-friendly and novel energy-saving building material, and the existing decorative material does not have a plate structure formed by compounding two hard and brittle materials into a whole.

The existing integrated decorative plate is spliced with other panels when used, so that four sides of the existing integrated decorative plate are always grooved on a construction site, a large amount of dust is generated, constructors absorb a large amount of dust and greatly influence the health of the constructors, and the environmental protection coefficient is also reduced sharply due to the generation of the large amount of dust.
