Embodiment 1

[0065] The acrylic polymer emulsion (here adopts the American Rohm and Hass produced AC-261 acrylic emulsion polymer, its solid content is 49.5%~50.5%) mixed with water, while stirring, add rubber powder, rubber powder:polymer emulsion:water=8:1:2.5 (mass ratio). According to the mass ratio, the rubber powder consists of 50 parts of ordinary Portland cement 425R, 20 parts of quartz sand, 0.2 parts of water reducer (Melment F10 produced by Degussa, Germany) and 0.2 part of defoamer (using Dehydran 1922 produced by Corning Company) is pre-mixed. After stirring evenly, make up points and level the base surface, and use a ruler to control the flatness, so that the height error within 2m is not greater than 3mm to become a leveling layer. The compressive strength of the leveling layer 28d is greater than 32MPa, the flexural strength is greater than 9MPa, and the bonding strength is 1.8Mpa.

Embodiment 2

[0067] The acrylic polymer emulsion (here adopts the American Rohm and Hass produced AC-261 acrylic acid emulsion polymer, its solid content is 49.5%~50.5%) mixed with water, while stirring, add rubber powder, rubber powder:polymer emulsion:water=4:1:1 (mass ratio). According to the mass ratio, the rubber powder consists of 50 parts of ordinary Portland cement 425R, 20 parts of coarse rubber particles with a particle size of 1-3 mm, 0.2 parts of water reducer (Melment F10 produced by Degussa, Germany) and 0.2 parts of dispersant. The foaming agent (Dehydran 1922 produced by Corning Company) was pre-mixed. Scrape the mixed slurry with a batch knife for construction, and there should be no obvious batch marks on the surface. The thickness is about 2mm. After 24 hours, polish the surface of the elastic layer until there is no obvious unevenness. Continue to maintain for 2 days until the rubber particles cannot be removed by hand. The Shore hardness (Shore A) of the elastic l...

[0069] The acrylic polymer emulsion (here adopts the American Rohm and Hass produced AC-261 acrylic acid emulsion polymer, its solid content is 49.5%~50.5%) mixed with water, while stirring, add rubber powder, rubber powder:polymer emulsion:water=4:1:1 (mass ratio). According to the mass ratio, the rubber powder consists of 50 parts of ordinary Portland cement 425R, 20 parts of fine rubber particles with a particle size of 0.1-0.5 mm, 0.2 parts of water reducer (Melment F10 produced by Degussa, Germany) and 0.2 parts The defoamer (Dehydran 1922 produced by Corning Company) was pre-mixed. Scrape the mixed slurry with a trowel, and there should be no obvious batch marks on the surface. Batch scraping about 1-2mm. After 24 hours, polish the surface of the elastic layer of fine rubber particles until it feels smooth without roughness. The thickness of the elastic layer was 1 mm. Preserve for 2 days until the rubber particles cannot be picked out by hand. The Shore hardness (...

Abstract

The invention provides a composite elastic terrace. The terrace comprises a rough rubber elastic layer, a fine rubber elastic layer and a wear resistant layer, which are sequentially arranged on a base from bottom to top, and two adjacent layers interpenetrate each other; the rough rubber elastic layer is formed by polymer coarse rubber particle cement mortar, the fine rubber elastic layer is formed by polymer fine rubber particle cement mortar, and the wear resistant layer is formed by an aqueous polyurethane paint. According to the invention, the terrace base, a toweling layer and the rubber particle elastic layers of the composite elastic terrace are all cement-based materials, and therefore, bonding between every two layers is good and the composite elastic terrace does not have the congenital defects like cracking and shedding among layers of an acrylic acid terrace; the wear resistant layer is made of the aqueous polyurethane material, which enables the problem of environmental unfriendliness of an elastic layer of polyurethane elastomer to be overcome and the advantages of good wear resistance and scratch resistance and environmental protection to be obtained.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a composite elastic floor. Background technique [0002] In recent years, with the rapid development of my country's sports industry, the amount of ground pavement in stadiums and outdoor sports venues is increasing. The variety and quality of paving materials not only affect the service life of materials, but also affect the use of sports venues. The versatility of paving materials has become a key indicator to measure the quality and grade of buildings. The current paving materials are mostly acrylic elastic floor materials and polyurethane elastic floor materials. In today's world, the "sustainable development" of the ecological environment has become one of the development strategies of many countries. The environmental protection awareness of various enterprises and consumer groups has been continuously strengthened, and users have gradually accepted environmentally f...
