Composite inorganic board and its making method

Abstract

The invention relates to a composite inorganic plate, which comprises one or more inorganic plate base layer, wherein the surface of base layer is rough, with pinhole and bad parts; the surface of base layer with vacuum plastic uptake has one layer of transition layer which is smooth and permeable; the transition layer is vacuum plastic uptake with one layer of polychloroethylene. The inventive production comprises that: the vacuum plastic uptake should adhere one transition layer. The inventive plate has low cost, high quality and simple production.

Description

technical field [0001] The invention relates to a composite inorganic board and a manufacturing method thereof, in particular to a method for vacuum forming on the inorganic composite board. . Background technique [0002] The traditional vacuum blister process is mostly used in the fields of finished furniture, cabinet door panels, speakers, packaging, etc., which requires very high surface accuracy and simulation (according to the surface shape of the substrate, the processed product can truly reflect the shape of the substrate. Surface condition) is a very good process, so the surface of the substrate is required to be relatively smooth and flat, and it is convenient for high-precision grinding. [0003] The existing substrates for blister treatment on the board are medium-density boards that are easy to deep-process, because the surface of the medium-density board is relatively smooth and flat, and it is convenient for high-precision grinding, which can easily achieve t...

Problems solved by technology

However, because MDF is an organic board, due to the characteristics of MDF itself, the quality of the products formed by this process is not very satisfactory, especially in terms of physical properties of the products, there are many shortcomings. For example, the product is relatively easy to be affected by moisture and has a high water absorption expansion rate. These properties make the product extremely unstable, easy to deform, and the PVC skin is easy to peel off from the base material; it is poor in insect and mildew resistance; and it cannot meet the office environment in terms of fire protection. requirements, especially in high-rise buildings and some places with special requirements for fire protection, it is impossible to meet the requirements of B1 level or above in fire protection; in terms of environmental protection, the free formaldehyde contained in MDF is only It can be removed by fumigation with ammonia gas, but some free formaldehyde still remains after removal, which cannot meet the environmental protection requirements

[0004] Inorganic panels do not have the above-mentioned shortcomings of MDF, but due to the existing manufacturing level, the surface appearance of the produced inorganic panels has obvious defects, such as rough surface, pinholes and other defects, and it cannot be polished with sandpaper , the board is relatively brittle, and it is easy to chip edges and corners when cutting

Therefore, in terms of inorganic boards, such as glass magnesium boards, which have been used in traditional decoration fields, the magnesium boards are directly nailed to the keel that has been made, and then fanned on it, and then decorated with ICI, or on the surface. Paste wallpaper on it, or paste veneer panels on it and then oil varnish, or paste fireproof boards on it for decoration; no matter what kind of decoration, it will take a long time for on-site construction, which will cause a lot of noise pollution and air pollution to the environment etc., and the surface decoration is relatively rough, the grade is not high, and the possibility of re-use is very good, causing a certain waste of energy, which does not meet the requirements of a conservation-oriented society, and the cost-effective production method is relatively low

[0005] However, if the surface of these existing inorganic plates is to be vacuum-absorbed, the surface of the inorganic plates must first be treated to be relatively smooth and flat, and it is convenient for high-precision grinding. Existing attempts are all to improve the manufacture of inorganic plates process to meet the requirements of vacuum blistering or to treat the surface of the inorganic sheet itself to meet the requirements of vacuum blistering, or the cost is extremely high, unable to meet the needs of the market, or failing to meet the requirements of vacuum blistering, so there is no such thing as yet. A vacuum-absorbing method for inorganic plates with low cost and good forming effect
