Abstract
The invention discloses a kind of preparation method of low smell high resilience polyurethane foam, this method is reacted with liquefied mdi using the polyethers and polyurethane auxiliary agent and water of low VOC, is prepared low smell high resilience polyurethane foam；It is specific as follows: low VOC polyethers, polyurethane auxiliary agent, water being stirred in proportion, liquefied mdi is then added, low smell high resilience polyurethane foam is made in foaming after high-speed stirred mixing.This method uses the polyethers and polyurethane auxiliary agent of low VOC, reacts with liquefied mdi, high resilience polyurethane foam resilience obtained is good, and smell is low.
Description
Technical field
The invention belongs to the preparation method of foamed plastics, specifically a kind of system of low smell high resilience polyurethane foam
Preparation Method.
Background technique
High resilience polyurethane foam is widely used in mattress, sofa, automobile-used cushion, but the gas of high resilience polyurethane foam
Taste influences the smell and health of people.
Summary of the invention
The object of the present invention is to provide a kind of preparation methods of low smell high resilience polyurethane foam, obtained in this way
Polyurethane foam resilience is good, and smell is low.
The purpose of the present invention is achieved through the following technical solutions:
A kind of preparation method of low smell high resilience polyurethane foam, it is characterised in that: this method uses the polyethers of low VOC and gathers
Urethane auxiliary agent and water, react with liquefied mdi, prepare low smell high resilience polyurethane foam；It is specific as follows:
Low VOC polyethers, polyurethane auxiliary agent, water are stirred in proportion, liquefied mdi is then added, is sent out after high-speed stirred mixing
It is brewed to obtain low smell high resilience polyurethane foam.
In the present invention, the low VOC polyethers is NJ-330V；Low VOC polyurethane auxiliary agent be low VOC silicone oil B8715LF2,
Low VOC catalyst MP610；Water meets laboratory three-level water requirement；Liquefied mdi is liquefied mdi 2020.
The low VOC polyethers, low VOC polyurethane auxiliary agent, water, liquefied mdi usage ratio are as follows:
NJ-330V:100 parts of low VOC polyethers；B8715LF2:1 parts of low VOC silicone oil；MP610: 0.5 part of low VOC catalyst；Water:
3-4 parts；2020:55-70 parts of liquefied mdi.
The present invention use low VOC(low molecular weight volatile object) polyethers and polyurethane auxiliary agent, reacted with liquefied mdi, it is obtained
High resilience polyurethane foam resilience is good, and smell is low.The foaming agent that this method, which does not use, to be influenced global warming, consume ozone, and
And only participate in reacting with water, environmental protection effect is good, and how much the dosage of water directly influences the density of polyurethane foam.
Specific embodiment
A kind of preparation method of low smell high resilience polyurethane foam, this method are helped using the polyethers and polyurethane of low VOC
Agent is reacted with liquefied mdi, prepares low smell high resilience polyurethane foam.Wherein, low VOC polyethers used is that Jurong Ningwu is new
The low VOC polyethers NJ-330V of the high rebound foam of 5000 molecular weight of material limited liability company production；Polyurethane auxiliary agent used
Including silicone oil, catalyst, silicone oil is the low VOC silicone oil B8715LF2 of Ying Chuan company, and catalyst is that the low VOC of Ying Chuan company is catalyzed
Agent MP610；Liquefied mdi is pure MDI(methyl diphenylene diisocyanate) it is obtained by chemical reaction introducing carbodiimide groups
The liquid product arrived can make the safer environmental protection of process for producing high resilience polyurethane foam, and this method uses
The liquefied mdi 2020 of Huntsman Corporation.
Low VOC polyethers NJ-330V, low VOC silicone oil B8715LF2, low VOC catalyst MP610, water are stirred in proportion mixed
It closes, liquefied mdi 2020 is then added, low smell high resilience polyurethane foam is made in foaming after high-speed stirred mixing.
