Turpentine-containing polyurethane foamed material

Abstract

The invention relates to the field of polyurethane, particularly a turpentine-containing polyurethane foamed material which is prepared by carrying out mixing, casting, reaction and curing on a material A and a material B. The material A is composed of the following components in parts by weight: 100 parts of styrene, 10-12 parts of turpentine, 4-5 parts of water, 6.0-8.0 parts of polyacrylamide, 1.1-1.3 parts of isoprene, 25-30 parts of ceramic slag powder, 3-4 parts of pentaerythritol, 5-7 parts of calcium carbonate, 1-2 parts of polyoxypropylene glycerol ether, 1-2 parts of butyl polyacrylate and 6-8 parts of modified attapulgite. The material B is composed of 30-40 parts by weight of polyisocyanate. The turpentine-containing polyurethane foamed material has the adsorption function, and has excellent flame retardancy. The polyurethane foam prepared from the turpentine is environment-friendly and degradable, has the advantages of wide turpentine sources and low cost, and overcomes the defect of high cost in the polyurethane foam.

Description

technical field [0001] The invention relates to the field of polyurethane, in particular to a polyurethane foam material containing pine oil. Background technique [0002] Polyurethane foam is made of isocyanate and hydroxyl compound through polymerization and foaming. According to its hardness, it can be divided into two types: soft and hard, of which soft is the main variety. Generally speaking, it has excellent elasticity, softness, elongation and compressive strength; good chemical stability, resistance to many solvents and oils; excellent abrasion resistance, 20 times larger than natural sponge; and excellent processing It is a kind of cushioning material with excellent performance, but the price is relatively high. Polyurethane foam is generally only used for cushioning packaging or cushioning materials for high-end precision instruments, valuable instruments, and high-end handicrafts, etc., and can also be made into exquisite and extremely protective packaging contai...
