Embodiment 1

[0025] A preparation method for a soft floor, which pretreats polyether to obtain a flame-retardant polyether, mixes the flame-retardant polyether and liquefied MDI evenly, and adds it into a mold through a pouring machine, and the injection time is 18 minutes. Spray the release agent, keep it in the mold for 45 minutes, and then take the formed floor mat out of the mold. After trimming the burr, rolling exhaust and shaping, compound the TPU film to obtain the product. After use, the mold is cleaned with The agent is recycled after washing;

[0026] The polyether is a polyether polyol, which is composed of a mixture of two types of polyether polyols, 330N and 3628. The pretreatment method of the polyether is to add the polyether into the stirred reactor and heat it to a temperature of 40°C. Then mix for 30min under the condition that the stirring speed is 175r / min, then add foaming agent, catalyst, chain extender, chain extender, foam stabilizer, antibacterial agent, flame ret...

Abstract

The invention discloses a preparation method of a soft floor. Polyether is pretreated to obtain flame retardant polyether, the flame retardant polyether and liquefied MDI are uniformly mixed, and thenfed into a mold through a casting machine, the injection time is 15-20 min, the mold is sprayed with a mold release agent before use, after thermal insulation placement in the mold for 30 to 60 minutes, a formed floor mat is taken out from the mold, after trimming of burrs, rolling for and venting, and sizing, a TPU film is compounded to obtain the product, and the used mold is washed with a cleaning agent for recycling. The soft floor has good anti-skid performance and good environmental friendliness, each test index satisfies national standards, and the soft floor has simple manufacturing process and low cost.

Description

technical field [0001] The invention relates to a method for preparing a soft floor, which belongs to the field of decorative materials. Background technique [0002] In many public places or indoors, elastic foam pads are installed to play the role of anti-slip, beautiful and elastic. However, the current conventional foam pads have poor anti-slip performance, especially in the presence of water, and are not environmentally friendly. Harmful gases will be released, which will affect the human body, especially the elderly and children. Contents of the invention [0003] In view of this, the invention provides a method for preparing a soft floor, which has good anti-skid performance, good environmental protection, each detection index meets the national standard, and the manufacturing process is simple and the cost is low. [0004] The present invention solves the above technical problems by the following technical means: [0005] A method for preparing a soft floor accor...
