Belt type foaming forming machine for producing synthetic leather

Abstract

The invention relates to the field of equipment for manufacturing polyurethane synthetic leather, and in particular relates to a belt type foaming forming machine for producing synthetic leather. The belt type foaming forming machine comprises a stand, a base material guide roll (22), a release paper guide roll (23) and a foaming and curing forming mechanism, wherein the foaming and curing forming mechanism comprises an upper forming belt mechanism and a lower forming belt mechanism, a foaming gap is formed between the upper foaming belt mechanism and the lower foaming belt mechanism, the base material guide roll (22) and the release paper guide roll (23) are respectively arranged on the top and bottom of the stand, and the foaming and curing forming mechanism is arranged between the base material guide roll (22) and the release paper guide roll (23). The invention has the beneficial effects that 1, the belt type foaming forming machine is matched with bicomponent polyurethane to produce the synthetic leather so as to replace the traditional wet leather production process; and 2, production links are reduced, the productivity is improved, in addition, energy consumption and environment pollution are reduced greatly, and the high-quality polyurethane synthetic leather is obtained.

Description

technical field [0001] The invention relates to the field of polyurethane synthetic leather manufacturing equipment, in particular to a belt-type foam forming machine for producing synthetic leather. Background technique [0002] At present, the production methods of polyurethane synthetic leather mainly include two categories: dry method and wet method. Both methods use polyurethane resin pellets dissolved in organic solvents to form a slurry, and then use a coating machine to scrape the slurry. Forming a coating on a substrate, it is well known that organic solvents are very serious in air pollution and pose a threat to the health of producers. However, production enterprises have invested a large amount of exhaust gas recovery equipment and wastewater treatment facilities, but exhaust gas recovery and wastewater treatment require a large amount of energy consumption, which continuously increases production costs.

[0002] At present, the production methods of polyurethane synthetic leather mainly include two categories: dry method and wet method. Both methods use polyurethane resin pellets dissolved in organic solvents to form a slurry, and then use a coating machine to scrape the slurry. Form a coating on the substrate. It is well known that organic solvents are very serious in air pollution and pose a threat to the health of producers.

However, production enterprises have invested a lot of waste gas recovery equipment and wastewater treatment facilities, but waste gas recovery and waste water treatment require a lot of energy consumption, which makes the production cost continue to increase
