Preferably, the catalyst includes triethylene diamine and stannous octoate, counts in parts by weight, ester ether foam each component Part by weight it is as follows：
Preferably, the stabilizer is silicon stabilizer.
A kind of preparation method of ester ether foam, including step are as follows：
S1：Material temperature is controlled at 20-24 DEG C, then feeds injection into mixing chamber by weight proportion, wherein, polyethers is more First alcohol 40-80 parts, 20-60 parts of polyester polyol, 25.5-52 parts of isocyanates, 1.5-4 parts of water, 0.27-1 parts of catalyst, stablizes 0.5-3 parts of agent；
S2：Raw material is stirred, injects die cavity after stirring evenly；
S3：Product is obtained after being reacted in die cavity.
Preferably, in S1, the catalyst includes triethylene diamine and stannous octoate, and the part by weight of ester ether foam is such as Under：40-80 parts of polyether polyol, 20-60 parts of polyester polyol, 25.5-52 parts of isocyanates, 1.5-4 parts of water, triethylene diamine 0.15-0.6 parts, 0.12-0.4 parts of stannous octoate, 0.5-3 parts of stabilizer.
Preferably, in S2, the rotating speed of the mixer is 2500r/min, mixing time 2-4s.
The remarkable result of the present invention is：
1st, existing polyethers foam and polyester foam present invention incorporates polyethers foam and gather there are respective performance deficiency The respective advantage and disadvantage of ester foam, have the other performances such as good physical property, chemical property and heat resistance, use scope is more Extensively, it compensate for the deficiency of existing foam material.From physical property, the intensity of the mechanical property of ester ether foam is better than polyethers Foam, flexibility are better than polyester foam, are chemically seen in performance, and the water resistance of ester ether foam is better than polyester foam, oil resistance Better than polyethers foam, from heat resistance, the heat resistance of ester ether foam is better than polyethers foam.
