Problems solved by technology

In addition, more than 60% of the particles in the magnesium reduction slag have a diameter of less than 150 microns, which are difficult to settle when suspended in the air. With strong moisture absorption, it is easy to make the soil salinized, and the land and surrounding areas accumulated with magnesium reduction slag can hardly be used for agricultural cultivation, thus causing long-term harm to the environment

Embodiment 1

[0034] 1. Preparation of dry film fines

[0035] Use 0.1mol / L NaOH solution to carry out alkali treatment (alkali boiling) on ​​the waste dry film, wherein the mass ratio of NaOH solution to waste dry film is 2:1, and the temperature of the alkali treatment is controlled at 90°C, and the time is 120min. An alkaline treatment solution is obtained.

[0036] The above alkali treatment solution was filtered to obtain a water-containing dry film dispersion slag, which was ventilated and dried, wherein the drying temperature was controlled at 100° C. and the drying time was 120 minutes to obtain a dry film dispersion slag.

[0037] The above dry film dispersion slag is crushed and sieved to obtain dry film fines with an average particle size of 120 mesh and a water content of <1%.

[0038]Adopt Fourier transform infrared spectrometer and pyrolysis gas chromatography-mass spectrometer to detect above-mentioned dry film fine material; The content is 2.4%.

Abstract

The invention provides concrete prepared by utilizing an abandoned dry film and a preparation method thereof. The concrete comprises the following components in parts by weight: 5-15 parts of dry filmfine, 5-15 parts of magnesium reducing slag, 10-20 parts of cement, 20-30 parts of natural sand, 20-30 parts of stones, 10-15 parts of water and 5-10 parts of a water reducing agent, wherein the dryfilm fine is obtained by carrying out alkali treatment on the abandoned dry film, and mass content of a colloid component in the dry film fine is less than or equal to 3%. According to the invention,the abandoned dry film and magnesium reducing slag are recycled, and the concrete with excellent mechanical properties is obtained.

Description

technical field [0001] The invention relates to a building material, in particular to a concrete prepared by using waste dry film and a preparation method thereof. Background technique [0002] Photoresist is a light-sensitive mixed liquid composed of photosensitive resin, sensitizer, solvent and other components. The photosensitive resin in the photoresist can quickly undergo photocuring reaction in the exposure area after being illuminated, so that the physical properties such as solubility and affinity will change significantly. After being treated with an appropriate solvent, the soluble part can be removed to get the desired image. In view of the photoresist's function of blocking electroplating and etching, it is widely used in the production and transfer of circuit components, solder resist masks and dielectric patterns in the circuit board industry. [0003] DuPont of the United States developed a photoresist (usually named dry film) in 1968, which is composed of p...
