Abstract
The invention aims to provide safe, effective, lasting, convenient and health concrete materials on the basis of raising the bearing capability of present concrete materials. The polymer contains one to three components selected from the group consisting of a block polymer which is copolymerized by the soft segment of polyethylene glycol (molecular weight being 1000-20000) and the hard segment of polyurethane, polyacrylamide, polyvinyl acetate, and a polyacrylate copolymer; additives are a negative ion-releasing auxiliary agent and a surfactant; asphalts are natural bitumen, petroleum asphalt and coal tar pitch; concretes contain one, two or more than two mixed inorganic compounds selected from the group consisting of common concrete, cold-resistant concrete and corrosion-resistant concrete. The negative ion-releasing asphalt concrete pavement materials with negative ion number being over 600 have the same technology as the common concrete mixing, and are a new generation of concrete materials. When contacting with air, the negative ion-releasing asphalt concrete pavement materials can constantly release hydroxyl negative ion. Therefore, indoor and outdoor harmful gases such as formaldehyde, ammonia and benzene which are released from decoration, furniture and exhaust gases are eliminated through integrated processes of charge neutralization, physical adsorption and chemical reaction and the like, thus keeping human body healthy.
Description
Technical field:
The invention belongs to material, chemistry, chemical industry, aerospace, health, environmental protection, building, field of traffic.
Background technology: the development of concrete material, environmental protection, healthy trend are arranged
Along with the development of society, people are more and more higher to the requirement of healthy material, can discharge the negative ion modified polymer material to the more and more attention that are subjected to the scientific worker of the living environment of improving people.。How when improving ground surface material integrated carrying ability, improving the environment protection health of concrete material, is that the problem that the researchist extremely pays close attention to is divided the problem of paying close attention to.
Whether the Air quality of weighing now an area surroundings in the world is normal, is not to be standard whether oxygen to be arranged, but is standard with certain content of negative ion.The international standard of fresh air is: contain negative ion 1000-1500 in must having every cubic centimetre.Statistical information according to the U.S. shows, 20 beginnings of the century, the ratio of positive and negative ion is 1: 1.2 in the atmosphere, and present ratio is 1.2: 1.1.The human Air quality of depending on for existence of this explanation is descending, and this will cause the ability of adjustment in the human body weak gradually, makes a large amount of crowds be in sub-health state.And anion material can improve negative ion concentration in the air, has function such as purify air, antibiotic, and people just constantly develop, develop and have the material that discharges negative ion, and anion material is more and more paid attention to by people.
Background technology:
Along with the raising of people to health requirements, simple environment-friendly materials have been not enough to satisfy people's demand, and material levels off to healthization day by day, so various healthy material, functional materials arise at the historic moment.Concrete is as people's indispensable material, and its healthization more is subjected to people's common concern.
The purpose of this patent invention is on the basis of improving existing concrete material supporting capacity, and a kind of safe, effective, lasting, convenient, healthy concrete material is provided.It is the concrete material of a new generation.Thereby, keep the health of human body when itself and endurable release hydroxyl negative ion after air contacts reach the obnoxious flavoures such as formaldehyde, ammonia and benzene that indoor and outdoor discharge in because of finishing and furniture and waste gas by combined processes such as electrical neutralization, physical adsorption, chemical reactions.
Summary of the invention:
