FR2806007A1 - Compound for absorbing oils, hydrocarbons and other liquid products with reflective, improved adherence and anti-slip characteristics - Google Patents

Abstract

Compound for absorbing oils, hydrocarbons and other liquid products on roads consists of an absorbent mineral with a granulometry of 0.3 to 1.3 mm, calcined at about 900 deg C with a mixture of silica glass granules of 465 to 800 microns m and micro-balls of treated or non-treated silica glass with a diameter of up to 1.3 mm.

Description

RETROREFLECTIVE ABSORBENT FOR FLOORS. The present invention relates to a product for absorbing oils and hydrocarbons or other liquid products, on roads, highways and pedestrian areas, in order to ensure safety for users.

Today's absorbents for floors widespread on the market do not allow vision at a distance and at night or in dark and overcast weather, which no absorbent of soil presently presents.

The invented product overcomes this drawback. It in fact comprises complementary products which overcome this drawback and make it a homogeneous product of high security.

It is indeed an absorbent of the mineral type calcined at approximately 900 C or more and having a particle size of 0.3 to 1.3 mm, of the Si02 type (MONTMORILLONITE, TERRE DE DIATOMEE, ATTAPULGITE, or all the others calcined absorbent products), mixed with Si02 glass granules of 425 to 1000 microns with sharp edges for adhesion and anti-slip and S! 02 glass microbeads treated with Silane or without treatment for retro-reflection, d '' a diameter of up to 1.3 millimeters. To ensure increased visibility at long distance (about 400 meters).

The compound has a homogeneous mixture of si02 (aluminum silicate and magnesium hydrated at about 75%). The purpose of this new product a) To absorb oils, hydrocarbons or other liquid products on the soil.

b) Improve the grip of users (for vehicles, increase in SRT value) therefore increase grip and anti-slip.

c) Reflective power (retroreflective) for good visibility at a distance and prevention of the danger of slipping.

d) Greater safety for road users.

e) Greater safety for personnel working on the roads. f) Warn the road user of a danger.

g) Safe for the environment and humans COMPOSITION OF THE PRODUCT For a 20 kg bag or other packaging - 18 kg of absorbent of one of the types mentioned above, - 2 kg of glass granules (glass granules from 465 to 800 microns ) and microbeads of glass or other reflective granules of the same type with a diameter of up to 1.3 mm, i.e. a proportion of 10% which can be modified according to demand, country, or climatic conditions.

Ready-to-use mixture in 20kg bags or other packaging.

The objective of the dry mixture is not to modify the absorbent quality of the mineral product.

 The product is characterized by the following proportions for a 20 kg bag 14 kg of absorbent product, 4.8 kg of glass granules, 1.2 kg of retroreflective glass microbeads.
