preparation example Construction

[0028] A preparation method for low-VOC rubber floor, comprising the following steps:

[0029] Step S1: Ingredients: Accurately weigh various raw and auxiliary materials according to the formula requirements;

[0030] Step S2: raw material VOC treatment:

[0031] Raw and auxiliary materials are treated to reduce VOC before use, which can effectively reduce VOC in the finished product. The odor of some raw and auxiliary materials can be dissipated as much as possible through various measures such as parking, baking, and plasticization. The VOC of rubber flooring products mainly comes from three categories of materials: synthetic rubber, accelerators, and reinforcing agents. Which accounted for the largest proportion. So dispose of it before use.

[0032] After the styrene-butadiene rubber is purchased to the warehouse, the outer packaging is first removed to make it fully contact with the outside air. Under normal temperature conditions, the VOC inside is volatilized and dis...

Abstract

The invention provides a low-VOC rubber floor composition and a preparation method thereof, belongs to the technical field of rubber floors, and aims at controlling the VOC amount from the source and effectively reducing the VOC of the rubber floors by selecting the varieties of raw and auxiliary materials for producing and processing the rubber floors and selecting the VOC with zero odor or the raw and auxiliary materials with small output. In the production process of the rubber floor, a series of technological processes of VOC treatment such as raw and auxiliary material parking, baking and plasticizing, high-temperature and high-pressure vulcanization treatment, coating of a layer of urethane acrylate coating on the surface of a rubber plate, continuous constant-temperature baking VOC volatilization treatment on the back of the rubber plate, packaging, transportation and adsorption treatment and the like are carried out. The VOC content in the rubber floor is strictly controlled, the VOC content in the rubber floor can be volatilized and dissipated to a great extent before the rubber floor is sold, harmful substances in the rubber floor are greatly reduced, the harm to the body of a user is reduced, and the harm to the atmospheric environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of rubber flooring, and in particular relates to a low-VOC rubber flooring composition and a preparation method thereof. Background technique [0002] Rubber flooring is a kind of elastic flooring. Rubber flooring is a floor made of natural rubber, synthetic rubber and other polymer materials. After nearly 20 years of domestic promotion and development, rubber flooring has been more and more widely used in airports, hospitals, power plants, subways, trains, ships, office spaces, sports venues, cultural activity venues, urban underground transportation hub centers, precision workshops, etc. . [0003] Rubber flooring is a floor made of natural rubber, synthetic rubber and other polymer materials. Styrene-butadiene rubber and butadiene-butadiene rubber are synthetic rubbers, among which styrene-butadiene rubber is the main source of VOC volatilization. [0004] VOC is the English abbreviation of volatile or...
