Problems solved by technology

During transportation and construction, due to bumps, there are many missing edges and corners of permeable bricks, resulting in a certain amount of waste
In addition, when the permeable bricks are used for laying tactile nails and tactile strips, the wear or shedding during use will cause them to lose their original functionality

preparation example Construction

[0033] The preparation method of above-mentioned polyurethane modified epoxy resin can be well known to those skilled in the art, for example can be synthesized according to the method disclosed in (engineering plastic application, 2005,33 (5): 73~76) such as Hu Jiapeng, also can Commercially available, for example, the polyurethane modified epoxy resin can be purchased from Dongguan Tuoxin Composite Materials Co., Ltd., product number TX8810 polyurethane modified epoxy resin.

[0034] Optionally, the polyethersulfone modified epoxy resin can be disclosed according to Zhang Qiang et al. ("Research on Polyethersulfone Modified Epoxy Resin", Shanghai Paint, 2014, 52(3): 10-11) Synthesized by the method. The flexible polyurethane resin can be 8250B two-component polyurethane adhesive purchased from Beijing Gaomeng New Material Company.

[0035]In a preferred embodiment of the present disclosure, the flexible binder is polyurethane modified epoxy resin and polyethersulfone modifi...

Embodiment 1

[0047] This example is used to illustrate the composition of the present disclosure for preparing flexible permeable bricks.

[0048] Get 100 parts by weight of silica sand, 2.1 parts by weight of ME-2 type waterborne epoxy resin (contact angle is 62 °), 0.7 parts by weight of polyurethane modified epoxy resin (elongation at break after curing is 130%) and 1.2 parts by weight The curing agent TX-5501 was mixed uniformly to obtain the composition C1 for preparing flexible permeable bricks in this embodiment.

Abstract

The invention relates to a composition for preparing a flexible water permeable brick and the flexible water permeable brick. The composition comprises silica sand, a hydrophilic binder and a flexible binder, wherein regarding to 100 parts by weight of the silica sand, the content of the hydrophilic binder is 0.1 to 10 parts by weight, and the content of the flexible binder is 0.1 to 10 parts by weight. The composition provided by the invention contains both the hydrophilic binder and the flexible binder; according to the water permeable brick prepared by the composition, on the premise of ensuring a water permeation effect, the flexibility and the abrasive resistance of surface layer aggregate particles are improved, the transportation construction loss is reduced, the abrasion performance of a brick surface layer is improved, and the service life of the water permeable brick is prolonged. The water permeable brick provided by the invention can be applied in all water permeable brick application occasions, and can be extended to sports competition places such as playgrounds so as to replace a plastic runway.

Description

technical field [0001] The present disclosure relates to the field of building materials, in particular to a composition for preparing flexible permeable bricks and flexible permeable bricks prepared from the composition. Background technique [0002] Permeable brick is a new environmental protection building material product born to solve urban surface hardening, create a high-quality natural living environment, and maintain urban ecological balance. Noise reduction, sound absorption and other characteristics. Ordinary permeable bricks are generally formed by pressing porous concrete materials of ordinary crushed stones. During transportation and construction, due to bumps, the permeable bricks often lack edges and corners, resulting in a certain amount of waste. In addition, when the permeable bricks are used for laying tactile nails and tactile strips, they will lose their original functionality due to wear or shedding during use. Contents of the invention [0003] T...
