Problems solved by technology
[0003] The object of the present invention is to provide a composite ring powder pressed brick and its production method according to the shortcomings of the above-mentioned prior art. Resin fiber powder produced from copper and other useful metals is used as the main raw material, supplemented with a curing agent to make it a composite material resin fiber powder, and then pressed with fly ash and ordinary Portland cement, thus solving the long-term problem at home and abroad. The point of view that the cured resin cannot be recycled, solves the problems existing in the prior art

Embodiment Construction
[0016] The features of the present invention and other related features will be further described in detail below in conjunction with the accompanying drawings through embodiments, so as to facilitate the understanding of those skilled in the art:
[0017] As shown in Figure 1, the composite material ring powder pressed brick involved in the present embodiment has the weight percentages of its components: the content of resin fiber powder is 20-30%, the cement content is 12%, and the use of soda ash, The curing agent composed of sodium nitrate, potassium dichromate, sodium chloride, sodium sulfate, sodium carbonate and calcium lignosulfonate has a content of 5%, and the rest is composed of fly ash. Resin fiber powder is the powder of waste electronic circuit boards without components, and the particle size is not more than 28mm.
[0018] The ratio of each component in the above curing agent can be set according to the specific technical requirements, which is easily understood...

Abstract
The invention relates to a composite ring powder pressed brick and the producing method thereof, adopting the resin fiber powder obtained after processing electronic industrial wastes, circuit board without devices, and leftover materials to recover copper and other useful metals, as the main raw material, making the main raw material into composite resin fiber powder with the help of curing agent, and then pressing with flyash and common portland cement into the pressed bricks. And it saves land resources, implements resources recycling and besides, protects the environment.
Description
technical field [0001] The invention relates to building materials and their treatments, in particular to a composite ring powder pressed brick and a production method thereof. Background technique [0002] The state repeatedly prohibits the use of clay bricks in construction projects, and strictly restricts the use of soil to burn bricks to prevent large areas of land from being consumed, destroyed, and encroached. At the same time, it also avoids fuel consumption and pollutant emissions and protects the environment. The issue of material resources is very important. In addition, a large number of waste electronic circuit boards and their leftovers and miscellaneous materials produced by the growing national electronics industry have always been troubled by the industry. Although some recycling methods have appeared, the by-product ring fiber powder that has emerged has never been recovered. It has been well resolved, so the problem of secondary pollution is not ruled out....
