Problems solved by technology

[0004] The apparent density of the TDI system sponge is relatively low, the foaming volume is large, and it feels comfortable. However, it generally has the disadvantage of poor rebound performance, resulting in insufficient support and poor comfort, which limits its use in sofa cushions. , sofa backrest, sofa armrest, vehicle seat, mattress and other industries also limit its own value

Abstract

The invention discloses a TDI system soft polyurethane foam plastic product and a production method and a production system thereof. The invention belongs to the technical field of polyurethane products. Raw materials comprise, by weight, 100 parts of polyether polyol, 5-20 parts of talcum powder, 0.05-1.5 parts of silicone oil, 1-3.5 parts of triethylene diamine, 2-7.5 parts of water and 20-35 parts of toluene diisocyanate, and can comprise, by weight, 13 to 22 parts of carbon fibers, 16 to 27 parts of spandex and 3.3 to 4.2 parts of a coupling agent. The production method comprises the stepsthat the carbon fibers, the spandex and the coupling agent are mixed for 30-50 min at the speed of 300-500 r / min and then mixed with the remaining components for foaming. The prepared TDI system softpolyurethane foam plastic product has excellent resilience performance, supporting performance and use comfort. The invention also discloses the production system for improving the yield of the TDI system soft polyurethane foam plastic product.

Description

technical field [0001] The invention relates to the technical field of polyurethane products, in particular to a TDI system flexible polyurethane foam product and its production method and production system. Background technique [0002] Flexible polyurethane foam, referred to as polyurethane soft foam, is a type of polyurethane foam with certain elasticity and softness, and it is also the most used type of polyurethane product. And sponge is a kind of soft polyurethane foam plastics. It has a porous honeycomb structure inside and has good softness, elasticity, water absorption, water resistance, etc. It is widely used in sofa cushions, sofa backrests, sofa armrests, and vehicle seats. chairs, mattresses and other industries. [0003] TDI (toluene diisocyanate) system sponge refers to the sponge that adopts toluene diisocyanate as the sponge foaming raw material to make, and existing can refer to the Chinese patent application that application publication number is CN105294...
