specific Embodiment approach 1

[0015] Specific embodiment one: the alloy putty of the present embodiment is made up of two components of main body ash and curing agent, and the weight ratio of main body ash and curing agent is 100:2, and wherein main body ash is made up of following composition according to weight ratio: Saturated polyester resin: 100, accelerator: 2~4, epoxy resin: 4~6, carboxy-terminated nitrile rubber: 0.5~2, pigment: 5~8, filler: 80~120; curing agent consists of the following components Composition according to weight ratio: initiator: 100, pigment: 2-4, filler: 4-6. The unsaturated polyester resin is an air-drying unsaturated polyester resin; the accelerator is cobalt isooctanoate and N,N-methylaniline; the initiator is cyclohexanone peroxide and methyl ethyl ketone peroxide; the pigment in the main body ash It is gray pigment paste and titanium dioxide, and the filler is talcum powder; the pigment in the curing agent is yellow pigment paste, and the filler is fumed silica.

specific Embodiment approach 2

[0016] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the main body ash is composed of the following components according to the weight ratio: air-drying unsaturated polyester resin: 100, cobalt isooctanoate and N, N-methylaniline : 2~4, EP-618 # Epoxy resin: 5, carboxy-terminated nitrile rubber: 1, gray pigment paste: 0.1, titanium dioxide: 5, talcum powder 325 # : 100, talcum powder 800 # : 10; The curing agent is composed of the following components according to the weight ratio: cyclohexanone peroxide and methyl ethyl ketone peroxide: 100, yellow pigment paste: 3, fumed silicon dioxide: 5.

specific Embodiment approach 3

[0017] Embodiment 3: The fiber putty in this embodiment is composed of main ash and curing agent. The weight ratio of main ash and curing agent is 100:2. The specific ratio is shown in Table 1.

Abstract

The invention relates to an alloy putty which comprises main body ash and curing agent by the weight ratio of 100:2, wherein the main body ash comprises (by weight ratio) unsaturated polyester resin 100, accelerating agent 2-4, epoxy resin 4-6, carboxyl-terminated butadiene-acrylonitrile 0.5-2, pigment 5-8, filling material 80-120, while the curing agent comprises (by weight ratio) initiating agent 100, pigment 2-4, filling material 4-6.

Description

Technical field: [0001] The invention relates to a polymer putty. Background technique: [0002] Atomic ash is a kind of filling material, its scientific name is polymeric putty, it is mainly used for caulking and filling on the surface of metal and non-metal materials before painting, so as to obtain a flat and smooth appearance. Atomic putty is mainly made of unsaturated polyester. It is different from other existing synthetic resin putties in that it can adjust the curing speed with a curing agent and can be cured quickly. Its largest application market is currently mainly for automobile manufacturing and overhaul industry. With the continuous development of the domestic automobile industry, the types and output of automobiles are increasing, the competition among industries is becoming increasingly fierce, the appearance quality is becoming more and more eye-catching, and the quality requirements for putty are getting higher and higher. There are more and more varietie...
