Problems solved by technology

[0003] Traditional drop plastic products generally use PVC (polyvinyl chloride) as the raw material for the preparation of drop plastic particles. In the production process, a large amount of plasticizers are required. Most plasticizers are harmful to the human body and the environment, and the heat resistance of PVC And light resistance is extremely poor, it will decompose and produce hydrogen chloride under the conditions of heat and light, which is harmful to human health

Abstract

The invention provides dripping plastic superfine fiber synthetic leather and a production method thereof. The production method comprises the following steps of step 1, mixing solvent-free polyurethane resin, filler, a coloring agent and dispersant, performing grinding through a three-roller grinding machine, mixing with a solvent-free curing agent and filtering to obtain dripping plastic paste; step 2, drying superfine fiber suede superfine fiber synthetic leather; step 3, enabling the dripping plastic paste obtained in the step 1 to coat the surface of the superfine fiber suede leather through a mould under 20 to 130 DEG C through scraping, performing demoulding and drying 1 to 30 minutes in a 100 to 200 DEG C of a drying oven after feeding to obtain the dripping plastic superfine fiber synthetic leather, wherein the superfine fiber suede leather is obtained through treatment in the step 2. According to the dripping plastic superfine fiber synthetic leather and the production method thereof, the fastness is high, the strength is high, colloidal particles are full, colloidal particle colors are rich, the abrasion-resistant effect is achieved, the tensile strength and the tearing strength are high, the touch is soft, the durable effect is achieved, organic solvent residues are not produced, and the dripping plastic superfine fiber synthetic leather and the production method thereof can be widely applied to the fields such as high-class antiskid industrial gloves, high-class antiskid insoles and high-class sporting gloves.

Description

technical field [0001] The invention relates to a synthetic leather, in particular to a plastic-drop superfine fiber synthetic leather and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of the industrial level, more and more industries and fields have an increasing demand for plastic drop fabrics with good anti-skid properties, and the use of polyurethane microfiber synthetic leather with excellent physical properties (referred to as: Microfiber leather) prepared plastic drop fabrics rarely appear on the market. [0003] Traditional drop plastic products generally use PVC (polyvinyl chloride) as the raw material for preparing drop plastic particles. In the production process, a large amount of plasticizers are required. Most plasticizers are harmful to the human body and the environment, and the heat resistance of PVC It has extremely poor light resistance and will decompose under the conditions of heat and light...
