[0007] (3) Fabric contamination caused by sponges;
It is generally believed that the presence of antioxidants may have a positive inhibitory effect on some of the above yellowing, but at the same time may also play a negative role and promote the occurrence of other types of yellowing

preparation example Construction

[0026] The invention provides an anti-burning core antioxidant composition and a preparation method and application thereof.

[0027] In this article, the range represented by "a value to another value" is a general way to avoid listing all the values ​​in the range one by one in the specification. Therefore, the record of a specific numerical range covers any numerical value in the numerical range and the smaller numerical range defined by any numerical value in the numerical range, as if the arbitrary numerical value and the smaller numerical value are clearly written in the specification The scope is the same.

Embodiment

[0030] The anti-burning core antioxidant composition provided in this embodiment has the following components and addition amounts:

[0031]

[0032]

[0033] Among them, the stabilizer is triisopropanolamine.

[0034] The preparation method of the anti-burning core antioxidant composition is: adding each component into a mixing kettle, slowly heating to 50-60°C under nitrogen protection, fully stirring for half an hour, and filtering.

[0035] This embodiment also uses two commercially available antioxidants as comparative examples, and the two antioxidants are KYJ-1 and KYJ-2. The addition amount of both antioxidants is 4000ppm.

[0036] The cross-sectional photos of the sponge prepared by adding the anti-burning core antioxidant composition of this example and the above two commercially available antioxidants KYJ-1 and KYJ-2, please see figure 1 . From figure 1 It can be clearly seen that the core burning phenomenon of the sponge obtained by adding KYJ-1 and KYJ-2 is obvious, wh...

Abstract

The invention discloses an anti-core-yellowing antioxidant composition which mainly comprises the following components in parts by weight: 20-40 parts of antioxidant 1135, 20-40 parts of antioxidant 5057, 20-30 parts of antioxidant PDP, 5-20 parts of antioxidant 1076 and 1-2 parts of stabilizer. The anti-core-yellowing antioxidant composition can well solve the problem of core yellowing of the sponge, and can enhance the yellowing resistance of the sponge to some extent. The anti-core-yellowing antioxidant composition has the advantages of low volatile content, small odor and no BHT (butylated hydroxytoluene), is convenient for addition, and satisfies the requirements for environmental protection.

Description

Technical field [0001] The invention relates to an anti-burning core antioxidant composition, which is particularly suitable for adding polyether to prevent sponge core burning phenomenon. The invention also relates to a preparation method and application of the antioxidant composition. Background technique [0002] The antioxidant doses used in polyethers on the market are relatively large, such as re-antioxidant, BHT, 1076, etc. However, these antioxidants such as BHT, 1076 and re-antioxidant can not meet the requirements of sponge anti-burning core well, and they are With the gradual increase in market requirements, BHT and cheap reantis (cheap reantis because they contain too few antioxidant components) are also difficult to meet environmental protection requirements, and antioxidant 1076 has too low melting point, if it is not dried thoroughly There will be solvents with low volatility, and the antioxidant 1076 is in powder form, which is inconvenient to add, smelly, and has...
